Which Character Is Awesome In Both Their DC And Marvel Versions?

The two big comic companies have a ton of characters who basically occupy the same space. Two Kings of Atlantis. Two fast-running guys. A few stretchy guys. But which characters are equally awesome in either version? And which pair would you want to team up?

Please include a picture or comic-book cover for your chosen duo. And please mention their names, and why they're both awesome. Thanks!
