So, anime characters broke into the real world and start slaughtering people.

I'd choose the ability to dispense tentacles. Any Anime-character's no.1 enemy

Domon Kasshu from G Gundam or Kamina from TTGL.

Any weapon/powers? Any character?

Spoiler: Hayate Yagami from MSL Nanoha StrikerS.

Why?

1) The girl's a bloody walking nuke. Hell, without her own targeting spells in place, she takes an entire fucking bridge crew to aim her without killing everything in the general vicinity.

2) She's a tactical genius that could rival Lelouche or Light.

3) Personal army in the Wolkenritter. These characters are built into her weapon. Her army consists of a Lightning Bruiser swordswoman (Signum), a cute bruiser berserker (Vita), a support caster/healer (Shamal), a wolf familiar (Zafira), and a secondary device to up the power of anyone she works with (Rein).

Spoiler: Signum

Spoiler: Vita

Spoiler: Shamal

Spoiler: Zafira

Spoiler: Rein. Keep in mind that she's maybe three inches tall

I pick Popeyes powers of eating spinach then being able to do whatever the hell I want.
