So, what kind of action cartoon would be good for Adult Swim, you ask me?

That one's easy. Video Games anime knock-offs!

[insert the title of whatever videogame franchise AS is currently airing/advertising during their commercial breaks here]

Voila! "The next Dragon-Age Funimation anime co-pro"!

Here's some Pro Tips:

Zelda: Skyward Sword
Modern Warfare
Assassin's Creed
Saint's Row

All are acceptable for anime cutting edge mimicry.
