What I love about these pictures, taken from premiere Predator community site Hunter's Lair, is how incredibly beautiful and detailed the outfits are - and how much goofy fun people are having with them. I picked these images in particular because they all show the Predators in very human situations. It's my crazy dream to one day walk into my local grocery store and just run into a Predator in the aisles - or maybe out in the parking lot, being led around by a hot lady in leather. Hey, it could happen. And I've got the photos to prove it!

It's almost Halloween, but you still need an idea for a DIY costume that will be the envy of all fanboys and girls across the galaxy? Lucky for you, Star Wars fans are a crafty bunch and they have plenty of tips for everyone from the most-advanced to the laziest costumer.

For those of you wanting to create a more authentic look to your Boba Fett costume, here's a handy video tutorial on how to weather his cape using a pizza cutter, cardboard and spray paint!

For the younglings in your life, here's a super-easy craft tutorial on how to make an adorkable DIY Kids' Yoda costume by Craft magazine's Susan Beal:

I used an Empire Strikes Back Yoda action figure for inspiration, and carried him around the fabric store to loosely match fabric colors to him and his outfit. The central piece, a simple brown robe, is altered from an adult T-shirt, and the other elements (a hat, snake, belt, and walking stick) are all quick sewing projects using basic templates.

If your Padmé Amidala costume is ready to go but you're not sure how to make your face look less like you've been wrestling with Acklays and more like you're ready to make out with a Skywalker, then this is exactly what was used on Natalie Portman in the films!

Check out these Padmé Make-up Pointers from Revenge of the Sith Make-up Supervisor Nikki Gooley:

Make-up by Nikki Gooley
Foundation: Make-Up Forever Face and Body foundation was applied in shade # 03. Concealer: Gooley used Shu Uemura Mark Concealer with Yves St Laurent Touche Eclat Concealer in # 03 under the eyes.
Powder: Gooley applied Visiora 003 Powder.
Eye shadow: Stila powder shadow in Barefoot Contessa # 33 was applied all over the lids. Then it was worked it up into the socket and blended out with Stila in Moonlight # 38. On the top lids, the lashline was lined with Stila shadow in Java # 8. Gooley then dabbed her browbones with Calvin Klein Eye Gloss.
Brows: Brows were filled in with Stila Convertable Eye Color Liner in Teak.
Mascara: Gooley used a classic favorite, Maybelline Great Lash in Black.
Cheeks: Stila Convertable Cheek Color, a cream blush in Peony, was dabbed on the apples of the cheeks and blended up onto the cheek bone.
Lips: Stila Lipstick in Jo was applied, then blotted. Gooley then used Elizabeth Arden 8-Hour Cream over the top of the lips. Gooley says that although it's usually used as a skin cream, she loves using it on lips because it gives them a nice, natural sheen.

Don't forget to give your dog a chance to show off his Sith or Jedi pride too! Craft magazine Senior Editor Natalie Zee Drieu made these cute Ewok, Darth Vader and Princess Leia dog costumes from felt, cotton fabric, yarn, and ribbon!

The trick about making quick Halloween costumes and especially ones for dogs is that you don't have to be perfect. Time is of essence here and we are all busy crafters. Since most of the costumes will only need to be worn for a few hours at most, cutting corners is definitely okay in my book. If you don't know how to sew or need to get it done in a snap — fabric glue, hemming tape, and sticker Velcro works wonders! Also, I used existing doggie jackets as pattern templates. Using these help me fit the dogs better and I didn't have to worry about doing too many fittings or wasting time creating patterns from scratch.

For the truly last-minute Star Wars costume, you can always print out and wear these vintage and prequel masks right now! Or do a mash-up and be a Sith Luchador!

Instead of Superheroes: Disney Mash-Ups

As much as I love a well-dressed Clark Kent with the Superman T-shirt peeking out from underneath his white button down, we've all seen it before. And sadly, the Watchmen idea is a little played out by now as well. I'm sorry, but the 1,000 Rorschach comic con cosplayers pretty much solidified Rorschach's status as this year's Joker costume. So mix it up, literally. Be a Disney Marvel Mashup like Mickey Venom here. It's clever, timely and most likely the most original costume you'll see all night.

Instead of Sexy Princess/Sexy Beloved Childhood Icons: Undead/Evil Princesses And Villains

Another Halloween, another batch of slutty Disney Princesses and beloved childhood characters getting sexified by the masses. Look, just because they make the costume, doesn't mean you have to wear it. Sexy Snow White and Rainbow Brite are TIRED. We suggest that if you're going to sexify a cartoon princess, do it with edge, twisted princess style — like this overhauled evil Alice get up from horrorland. You could even flip it around and be the baddie, we're actually kind of excited about sexy Maleficent, at least we haven't seen her around the block as many times as Snow White.

Instead of The Joker: Cesar's Joker

We get it, you really, really, really liked Dark Knight's Joker. Well so did millions of other people, which is why the streets are perpetually flooded with Jokers every year, The Office even poked fun at the Joker masses. This year if you must don the old purple suit, at least go retro Cesar Romero style. Don't forget the pencil-thin mustache.

Instead of Bloody Doctor: A Real Science Experiment Gone Wrong, District 9 Style

Every year one of my friends in the medical profession always half asses it with an old pair of scrubs and some fake blood. This is not scary, nor is it interesting. Put a timely spin on this look with a "Prawn" hand! Slap on a "property of MNU" and this amazing arm extension and BAM you're Wikus from District 9. Just remember to say "fook" a lot. Alien hand available on ebay.

Instead of Sexy Cat: Sexy Avatar Cat

Throngs of unwashed, mewing "sexy cats" prowl paws first through our city street every year. But this year, we beg of you, update your kitty ears and tails into a James Cameron approved sexy cat, an Avatar Na'vi. Plus 1,000 points if you wrap it in with Arrested Development's "never nude" shorts.

Instead of Darth Vader: Sexy Vader

While we all love a good Chewy and Han here and there, I'm a little tired of seeing poorly constructed Vaders. Give the old costume a whirl this year and throw a pair of heels on the Dark Lord.

Instead of Leia: Zombie Leia

Same thing that applies to Vader also applies to the tons of Leia costumes, switch it up, take her from beauty to undead lovely with a zombie twist!

This adult Halloween costume shows an alien in a prison suit, holding a green card. Get it???!!!! The second illegal alien hat has a dark mustache and baseball cap over space alien features. And you can tell our space friends are pissed.

The Coalition for Humane Immigrant Rights of Los Angeles explained that it had been receiving many complaints about the costume.

Jorge-Mario Cabrera, the director of communications for CHIRLA, said he initially thought the costume was a stab at harmless satire. But when he saw the Green Card, he realized it was an swipe at illegal immigrants.

Even though the costumes have been pulled from Target, the "drama" might be increasing the outfits attention. A Halloween costume supplier Ricky's in NY commented that the costume was doing pretty well and they had to order additional shipments. And William Gheen the president of Americans for Legal Immigration, even intends to purchase the costume and called the critics hyper-sensitive.

All month long we're running the io9 Halloween Costume Show in a Flickr pool. Want to show off this year's duds, or gems from Halloweens past? Show us what you've got! The one rule is that you can only post pictures of yourself - or yourself with friends. Every week we'll be rounding up some standouts, but there are a ton of great costumes that we don't get to feature - so check out the whole set on Flickr!

I utterly love these cute, matching homemade Dalek costumes. This is girl nerdery at its finest. Posted by xfanatic501.

Nick Philippi gives us his best numberless henchman of Monarch impression. Just in time for the new season of Venture Bros!

This is just holy crap weird and awesome. It's a World War II Aviator Gremlin. Created by Kory Bing, who posted more great costumes in the pool too.

Halloween is an emo time, as Crow knows. From Tasayu Tasnaphun.

We have been feeling tragic all week that atomicglassworks never got a picture of herself in this gorgeous "shipwreck" dress. How lovely is this?

Here is atomicglassworks in her She-Ra incarnation.

DynamiteLaserbeams created this costume of Tali'Zorah nar Rayya from Mass Effect. Wow.

Jen and Ted: Vulcanish Characters (Defying Gravity "Fear"): In lieu of Mr. Spock, the crew of Defying Gravity grew up watching a science fiction show featuring Dr. Ra. When Jen finds out Ted is attending the ship's Halloween party as Dr. Ra, she decides she'll dress as the pointy-eared babe from the same show. It's a little desperate, but less uncomfortable than Zoe's pregnant astronaut outfit.

Clark Kent: Zorro (Smallville "Thirst"): Shouldn't it be Bruce Wayne wearing the Zorro outfit? Clark tries on the costume for a sorority Halloween party. He doesn't dig the mask, but finds himself liking the cape.

The Doctor: Harlequin (Doctor Who "Black Orchid"): The Doctor does have a few Halloween encounters — in the audiodrama Invaders from Mars and the more recent novel Forever Autumn. But it's at a non-Halloween fancy dress party that we see him don a costume: a harlequin suit and mask. Unfortunately, someone else has stolen the costume and worn it to commit a murder.

Elisa Maza: Belle (Gargoyles "Eye of the Beholder"): Halloween is the one day a year the Gargoyles can go out among humans, but most of them decide to wear costumes anyway (creating the effect that they're wearing two costumes). Since this is a Disney show, Elisa dresses up as Belle, with an uncostumed Goliath serving as her Beast. In a Halloween issue of the comic, she attends a Halloween party dressed as Princess Jasmine, suggesting she has a mild obsession with the Disney princesses.

Chuck and Morgan: Sandworm (Chuck "Chuck vs. The Sandworm"): After a long hard day of protecting his nation's interests, Chuck indulges his geeky side at his Halloween party. Not only does Sarah show up in a Princess Leia slave bikini, he and Morgan do the worm in their Dune-inspired costume.

Anya: Fluffy Bunny Rabbit (Buffy the Vampire Slayer "Fear, Itself"): Buffy actually had three Halloween episodes, but after the first one — in which everyone took on the identity of the costumes they were wearing — most of the characters were a bit superstitious in their costume choices, venturing to Halloween parties as James Bond or Joan of Arc (although Oz's God costume was appropriately Oz). Anya, however, didn't disappoint with her absurd, all-out rabbit costume. Not scary, you say? Depends on how you feel about rabbits.

Young Ned and Digby: Bedsheet Ghosts (Pushing Daisies "Girth"): When Ned sneaks home to see his father on Halloween, he does the classic bedsheet ghost thing to remain incognito. And Digby, ever the faithful companion, accompanies him in matching attire.

Hank Venture: Batman (The Venture Brothers "Love-Bheits"): While the rest of the Ventures dress as Star Wars characters to enter a Halloween contest, Hank dresses up as "the Bat." In fact, Hank dresses up every Halloween as "the Bat." Hell, if Brock would let him, he'd wear his Batman costume on dates.

Stephen King: Pumpkin Head (Quantum Leap "The Boogieman"): In the strange Halloween episode of Quantum Leap, Sam leaps into the body of horror novelist Joshua Ray. The episode involves Sam battling the Devil (disguised as his holographic companion through time Al), but it also features "Stevie," Ray's young assistant who dresses up as a pumpkin-headed scarecrow for a local spook house — and it's heavily implied that Stevie is, in fact, a young Stephen King.

Wolfram & Hart Client: Human Being (Angel "Life of the Party"): One clever demon attending the annual Wolfram & Hart Halloween party decides to make his human suit out of real humans. What he failed to understand was that the new management (consisting mostly of current and former humans) considers this a bit of a faux-pas.

Sam: The Lucky Pumpkin (Reaper "Leon"): Now, Sam wouldn't actually choose to wear this monstrosity of a costume. It's simply another humiliation that comes with working at Work Bench. And let's face it, it can't even hold a candle to Sock's "Underwear Man" outfit.

Sari: Optimus Prime (Transformers Animated "Along Came a Spider"): Why not spend Halloween dressed as your personal hero? Sari even does a little imitation of Optimus Prime ("I'm Optimus Prime and I'm scared of spiders!"). Does this make her a robot disguised as a human disguised as a robot in disguise?

Gir: Xenomorph (Invader Zim "Halloween Spectacular of Spooky Doom"): Gir spends most of his time on Earth in costume, so it's only right that he gets into the Halloween spirit. Plus, an Alien xenomorph costume is apt since Gir is an alien, albeit a robotic one.

E.T.: Bedsheet Ghost (E.T. the Extra-Terrestrial): When's the best time to sneak an alien out of the house? Halloween, when you can throw a sheet over his head and convince your mom that he's your little sister.

Jessica Moore: Sexy Nurse (Supernatural "Pilot"): The Winchester boys aren't exactly fans of Halloween, and Sam didn't do the dressing up thing even before he became a monster hunter. But his girlfriend Jess spends Halloween as a sexy nurse shortly before she dies.

The Tick and Arthur: Each Other (The Tick Big Halloween Special): The Halloween special is actually involves the Tick confronting the man-eating bovine Mad Cow, but it's still nice to see he and Arthur trick-or-treating as each other on the cover.

Various Aliens, Robots, and Superheroes: Themselves: If you don't blend in with humanity the other 364 days of the year, Halloween is a handy time to show your face. ALF got a reprieve from his normal stir-craziness by attaching a zipper to his fur and pretending to be a kid in costume. The Teenage Mutant Ninja Turtles have ventured out of the house with costumes, though it quickly became clear then didn't need them after losing them in a fight. In the Farscape episode "Kansas," the Moya conveniently lands on Earth on the holiday, as do Andromus and Centuri in the Galactica 1980 episode "The Night the Cylons Landed." In the The Specacular Spiderman episode "The Uncertainty Principle," Peter Parker and Felcia Hardy show up at a Halloween party wearing their respective spandex — because, why not?

The image you see here is from Miss Fawn (with additional effects by Jim Brey), who posted her picture in our Halloween pool last year. You can enter any picture of yourself, or yourself with friends, as long as you are in some kind of Halloween costume. Do NOT enter pictures of other people.

Be the first to post your picture in io9's 2009 Halloween Costume Show pool here, on Flickr. Yes, you have to create a Flickr account to play, but it's free! You can see pictures from the 2008 costume show here. Alright - let's see your stuff! Next week we'll post our first round of cool shots.

It even forgot the whiskers and the crown! This whole incredibly overpriced fiasco just makes me mad/sad. This is not what this film should be about, and yet the video game and triple digit priced costumes keep getting in its way.

Update: The $460 hoodie is pretty bad too.

Joy designed the costumes for that haven of hipster merchandising, Urban Outfitters, and they are on display at the company's Space 15 Twenty store in Los Angeles, which is currently hosting a Where the Wild Things Are art show. The costumes are for sale, with proceeds going to the Los Angeles chapter of Dave Eggers' non-profit 826.

Costume designer Wanda Piety and prop master Dragon Drohnet were two of the judges for Saturday nights Masquerade, and were kind enough to give us a post-mortem on the show and offer their insight into what makes for a winning costume or performance. This is just a taste of the nearly four dozen entries to cross the Comic Con stage, but includes some of our favorites as well as the judges':

Forty-seven individuals and groups entered this year's Masquerade, showing off their most innovative sketches and costume designs. There were G.I. Joes and Skeletors aplenty, a singing Dr. Horrible and a singing Dr. Mrs. Monarch, and even a group that attempted to reenact all the best scenes from The Princess Bride. We'll have video of the performances soon enough, but here are the outfits the judges deemed best:

Honorable Mention: Excellence in Costuming — Red Death Phantom of the Opera

The Masque of the Red Death version of the Phantom of the Opera danced to "Masquerade," while occasionally pulling off his many masks, until he finally reached a skull.

Honorable Mention: Blast from the Past — Muppet Labs Masquerade Machine

Dr. Bunsen Honeydew took the stage, subjecting his hapless assistant Beaker to his Masquerade Machine while Statler and Waldorf heckled them from their portable balcony.

Honorable Mention: Technical Execution — ATST Scout Walker
The ATST wowed the judges with its jointed legs that walked as the person inside it walked.

Honorable Mention: Performance — Jawa Pimp
Jawa Pimp has his own theme song, which he boogied to while showing off his bling.

Honorable Mention: Workmanship — Toro the Minotaur

Honorable Mention: Recreation — The Hulk

Honorable Mention: Rock Golem

Best Young Fan — Samurai Jack vs. Aku
This father-son team was one of the big hits of the Masquerade, taking home several of the individual sponsored awards as well as a Comic Con trophy.

Best Novice — Aquaman
Aquaman surfed onto stage and into the judges' hearts with the song "I am Aquaman" and a full blond beard.

Most Beautiful — Mirka Fortuna "Trinity Blood"

Most Humorous — Welcome to the Dollhouse
A group of dolls from around the world marched on stage with Igor (toting his iGor mp3 player) and performed a perfectly choreographed rendition of "It's a Small World After All." That would have been funny enough, but they quickly burst out into an equally well-done "Thriller."

Best Performance — Bring It On (Rock the Mouse)
When you reimagine Disney heroes and villains as rival cheer squads and end it all with a rousing rendition of Toni Basil's Mickey, your sketch is full of win.

Best Workmanship — Lady of Pain "Planescape"

Best Original Design — Onigashima Baba

Best Recreation — Spawn

Judges' Choice — Looking Glass Wars

Best in Show — The Four Seasons

No word just yet on the price, but I'm estimating it will cost one adult human's dignity. While the armor is ridiculous and looked hot on Bale (strange stomach-muscle ridges aside) I'm pretty sure nobody else could pull off this look, let alone on a motorcycle. But if you can afford it — and I'm sure it's coming with a hefty price tag — more power to you.

An Officially Licensed Replica Like No Other is Coming.

- Strong Cordura Mesh Base with Heavy-duty 4 way stretch Spandex
inserts.
- Removable CE Approved Body Armor in both Jacket and Pants
- Highly detailed, removable lightweight interior lining.
- Form Molded Leather and Kevlar Armor Sectons.
- Made from Quality Tanned Cow Hides

- COMING SOON

Apart from the droves of Nurse Jokers, and the standard Star Wars fare (if there's a con with out a Stromtrooper I don't want to know about it), this year had a lot of surprises and classics. Of course there were the Jayne hats, because Joss Whedon was there...what else do you wear to see Joss?? But the biggest surprise was the sheer number of fans donning G.I. Joe wear. Also, is that a lady Snake Eyes I see? Enjoy the round up, and good work guys - especially you, Bat-Mite and Teen Titans.

Spider-Man	Star Wars	Ghostbusters
G.I. Joe	Comic Characters	TV, Movies And Random Fantastic
Watchmen	Batman	Jayne Hats

We could not have compiled this list with out the help from our many volunteers and the very talented Istolethetv and Ellen Wright. Please check out their amazing collections as well.

Erzingel shows us an ultra-daring shot of himself and his wife dressed as Hellboy and Hellgirl, posing with the man himself — Ron Perlman, who played Hellboy in Guillermo Del Toro's two flicks about ole Red.

And it's hard to resist evildead1971's Shaun of the Dead costume. Not only is he a serious cutie, but he's got the boldness and cred of having action figures (in their packaging!) pinned to the wall behind him.

But now it's time for intense daring. Our own io9 staffers Ed Grabianowski and Graeme McMillan have shared their boldest efforts at costumery. Ed is dressed as "Zebra-Man," who is always ready to throw down with some miniatures on the table top!

And Graeme shares with us a picture of himself from 1995, back when, he confesses, "I had hair, and lots of it." He refuses to explain exactly what he's dressed as, saying only that it "was supposed to be some kind of bat." Apparently his wife Kate simply shook her head when she discovered that he was actually putting this picture on the internet. All we can say is: Bold move, Graeme. Very bold.

Want to take a gander at all the other insanely cute and bold contributors to the io9 Halloween Costume Show Flickr Pool? Well follow the link and add your own!

Brown Coat, or random frontier person. We talked to Shawna Trpcic, costume designer for Joss Whedon's shows Firefly, Serenity, Dr. Horrible and Dollhouse. She's all about adapting easy-to-find materials — she cut up her own wedding dress to make Inara's ballgown in the Firefly episode "Shindig." Says Trpcic:

Thrift stores are a treasure source. You don't feel bad cutting something up to make it a-line or off center, to make it other-worldly. I love the "Towns" in cities - Chinatown, Little India, Thai-town — you can get amazing costume pieces for very little, [with] all the embroidery and beading. Crazy shoes, neat jewlery. The stores that supply "work" clothes are also great, for Amish, prairie, or cowboy. You can get thick pants, prairie dresses [or] patriot shirts. Again usually not very expensive. Then the planet you choose to be from will determine the make-up.

Random cyborg mutant. We got a similar answer from Ruth Secord, who's worked on a slew of TV movies including Threshold, Bugs, Terminal Invasion, and Encrypt. Go down to your local Army surplus store and "Value Village" type stores and look for random stuff that you can put together into a ramshackle survivor of the purge of humanity.
What you'll need: Scraps of rubber and leather. Pieces of chain mail. A pop riveter. Bits and pieces of electronics. Old Army uniforms.

Nerd Herder from Chuck. We talked to Augusta, aka burlesque performer Penny Starr, Jr., who works as a costumer on NBC's series about a nerd in an electronics store who gets the CIA and NSA databases plugged into his brain. And not surprisingly, Augusta suggests dressing as a member of the Nerd Herd, the team of computer fixers that Chuck belongs to.
What you'll need: "Black pants, white short sleeve shirt, grey tie and pocket protector."

Mork From Ork. The manic, happy-to-go-lucky, finger-drinking visitor from a crazy backwards planet, from the classic sitcom. He's due for a come-back, and I'm frankly shocked the Mork movie hasn't been announced yet.
What you'll need: Shaggy hair, vertical stripey suspenders, glue-on chest hair, and heaps of cocaine.

Steampunk person. Another suggestion from Augusta, the Chuck costumer. "There's nothing more 'in' these days than steampunk!" she says. For those who slept through the past two decades, Steampunk is about imagining an alternate Victorian era that achieved high technology (including cyborgs and stuff) powered by steam.
What you'll need: Victorian clothing. For men, a white shirt and fitted (not pleated) trousers. For women, a long, full skirt. Turn up your collar, and then buy a women's silk scarf and wrap it around your neck, with a knot, to make an ascot of sorts. Buy some goggles from the Army/Navy surplus store, and while you're there, ask if they have any gaiters, which are canvas leg coverings that go over your leg like spats. "Add a suit vest from the thrift store, and get a length of chain from the hardware store for your 'pocket watch' — buy a connector to clip it to the second to last button hole and connect the other side to your iphone!"

Bodypainted superhero. If you're bald and skinny, paint yourself silver and go as the Silver Surfer. (It may help to have a surfboard, also painted silver.) If you're a bit bigger, paint yourself green and go as the Hulk. (Or She-Hulk if you're a tall, buff woman.)
What you'll need: Bodypaint. And, if you're the Surfer, a surfboard and some silver paint.

Random Stargater: Our resident Stargate expert, Meredith, points out that the basic Stargate uniform is pretty simple — and very close to actual Army fatigues.
What you'll need: Basic Army fatigues. And a patch. You can be lame and just laser print it, or you can try and track down someone like this guy who makes the real thing. Ahh... just laser print it.

Off-duty Battlestar personnel. Particularly in the Battlestar Galactica miniseries, the Galactica crew had a pretty simple uniform for when they were off duty. And yet it has the advantage of being pretty recognizeable, because who wears a tanktop over a T-shirt normally?
What you'll need: cream/tan-colored T-shirt, olive-green or dark green tank top, and green fatigue pants. Bonus points if you're female and have short blonde hair.

Col. Doctor Irina Spalko, from Indiana Jones and the Kingdom Of The Crystal Skull. She's awesome and distinctive, but also quite simple. The only hard part is the sword, but you can probably use a toy for that.
What you'll need: A blue/grey jumpsuit, similar to what maintenance workers wear. Try your local thrift store and uniform supply store. Big black gloves, big black boots, and a big black belt with a gold buckle. (You can paint the star on it yourself.) And then there's that sword, which could totally be a toy, unless you can borrow someone's real sword. And finally, a shiny straight black wig with a bowl/fringe cut, which you can find in my neighborhood for $10. Boom, you're done.

Starman. This one's a suggestion from Annalee. Jack Knight takes over as the superhero Starman, the hero his dad invented, after his brother dies on the job. Jack spurns the spandexy costumes and big fins the original Starman went for, and instead goes with a simpler, but more kick-ass, outfit.
What you'll need: Black leather jacket, T-shirt, jeans. Big goggles. And you'll have to figure out a way to make your own power rod — Annalee suggests a broomstick with a globe attached.
Another T-shirty superhero costume: Captain Hammer, who just wears a black T-shirt and cargo pants. You just have to attach the trademark logo somehow, either by glueing it on or by getting it from a custom T-shirt store. (In my neighborhood, they have a two-hour turnaround now.)

And here's a bonus idea, that's a bit harder but still pretty doable:

Cassandra from Doctor Who. Okay, this one is a bit more ambitious, but not really as hard as it seems. Stay with me here. Cassandra is the self-proclaimed "last human," who's had so much plastic surgery that she's now just a piece of skin stretched across a frame. She's bitchy and fabulous, and always seems to be hatching plans to destroy all of the zillions of other people who could lay claim to being among the last humans.
What you'll need: A metal garment rack on wheels, some kind of thin tarp or flesh-colored plastic sheeting, some paints, a rubber brain, a glass tube, a white smock, white pants, some bandages, some goggles. What you do is, stretch the fake skin across the dress rack, and attach the brain to the base of the rack inside the jar, and paint eyes and mouth on it, plus maybe a few little veins. Then you dress in all white, with the goggles, and wheel "Cassandra" around. If you can throw your voice so it sounds like she's telling you to moisturize her, so much the better.
