I'd kills the ones who just don't know when to simply die off. Like a cockroach in a microwave, they want to continueslly come back every time you turn around for relie. This applies to all anime characters who just simply hate dying.
I'd kill lot of annoying whiny and girly girls like orihime (bleach), sakura (naruto, especially like she's at start), misa (death note) and anything like that, I just hate such girls, i'd just blow them up if i saw them in life
(i think we can all agree on this one) Chi Chi -DBZ(god i hate her)Freeza and the Ginyu force(the Ginyu force are so freaking annoying. i was jumping for joy when did die...well most of them. i laughed at what happened to captian Ginyu)-DBZ
everone in SD Gundam(hate that anime with a passion)
Kimblee ,Tucker and Dante-FMA
Mayu's father( i wanna kill him!)-Elfen Lied
Darcia-Wolfs Rain
Team Rocket-Pokemon
