This week in the world of cartoons, Captain America and Spider-Man break into the Latverian Embassy on Ultimate Spider-Man, Regular Show brings it with a half-hour Halloween special, Thor fights Hulk on Avengers: Earth's Mightiest Heroes, and we get to meet a new dragon on Riders of Berk!

As always - minor spoilers ahead!

Star Wars: The Clone Wars – "War on Two Fronts"


The Clone Wars quarter - Anakin, Obi-Wan, Rex, and Ahsoka, journey to the Separatist world of Onderon with the hopes of training a band of rebels to take the capital city. Lux Bonteri, the Lando Calrissian of The Clone Wars who appears to have feelings for Ahsoka, appears in this episode.

This clip features Anakin and Ahsoka instructing the band of rebels in the finer points of destroying droidekas.


Ultimate Spider-Man – "Not a Toy"


What Marvel character would lose Captain America's mighty shield? The Ultimate version of Spider-Man of course?

In this episode, Spider-Man and Captain America break into the Latverian Embassy in order to retrieve Cap's shield from Doctor Doom.


Avengers: Earth's Mightiest Heroes – "The Deadliest Man Alive"


The original Hulk is back after being cleared of atrocities committed by the Red Hulk. What should the Avengers expect from their old friend Bruce Banner, and can they trust him to be a fellow Avenger?

In this clip, the Hulk attacks Captain America with what looks like dead Christmas trees, followed by a classic moment featuring Thor vs. the Hulk.


Dragons: Riders of Berk – "How to Pick Your Dragon"


In this excellent episode (one of the season's best from the tease I saw at San Diego ComicCon), Stoick the Vast wants to learn how to ride a dragon. He chooses his son Hiccup's dragon, Toothless, as his own, but things don't go so well. Stoick eventually chooses the massive Thornado, making for a formidable pair.

There's lots of dragon action in this clip, as Hiccup shows Stoick the various types of dragons available in Berk.


Young Justice: Invasion – "Darkest"


Black Manta appears in this episode, playing tricks with Aqualads' mind and allegiances.

Will Aqualad save Impulse and Blue Beetle or let them be captured by the Manta?


Transformers: Prime – "Hard Knocks"


This episode continues the hunt for the second Omega. Dreadwing starts a forest fire and blows up the side of a mountain in an attempt to kill two Autobots. Smokey the Bear is not happy.

Starscream also gets some face time in this episode as he modifies his allocation of Red Energon.


Regular Show – "Exit 9B"


In this half-hour Halloween special, Mordecai and Rigby travel two months into the future to save their brainwashed friends from an ominous bearded man.

Check out this clip for some laser beam horror and an internship gone awry.


Green Lantern: TAS – "Reboot"


The Crisis-causing Anti-Monitor appears in this episode, urging Hal Jordan to unite Kilowog, Aya, and Razer to aid the new Honor Guard.


Gravity Falls – "Summerween"


What is better than Christmas in July? Grunkle Stan's annual Summerween party!

Will Dipper and Mabel be able to put up with crappy candy and avoid the Summerween trickster?


Adventure Time- "The Hard Easy"


Can Finn and Jake defeat Mega Frog and protect the honor of a group of Mud Scamps? The scamps are two-legged, talking fish on the verge of being ran off from their home and forced to get jobs in the real world.

Jonathan Katz from Dr. Katz provides the voice of Mega Frog in this episode, while Billy Murray's brother Brian provides the voice of one of the scamps.
