what would be the BEST way to kill the avatar above?

Slap you in the face with the horrible NES port he made. In the FACE!!

 

Airstrike.

 

There's only one way.Putting him up against Vash, duh.

 

just normal stab =p

 

tie her to the dog food factory

 

dip his feet in lava, hammer his dick to a wall with a long, rusted nail and pour hot wax on it, break both his legs with the same hammer, cut his gut open with a bloody(not his blood) scalpel and repeatedly pierce his insides with a needle, titty twist him with electrified tweezers, stuff a used plastic, melted hot spoon in his gut, and make him drink his blood

 

you're scaring me

 

choke her

 

A bullet to the head.

 

eat the last cookie in the world

 

get a metal gear to kill him

 

Kick his balls

 

just kill him

 

Final Flash.

 

...I think this wins. For any avatar.

 

crush cookie, lick repeatedly, rape, reform, make soggy, eat, poo out the remains and form it into the shape of a cookie, put maggots into brain (centre at least), put cookie crumbs into furnace, put ashes into urn, nuke it, throw it into black hole, retrieve it with his whole family, burn up his family, electrocute the atomized ashes with 5 tasers, corrode atoms (somehow) with hydrochloric acid, blow away into the midst of a supernova

 

Choke him.

 

Define "Best."

 

... Any normal human means, perhaps?

 

Love him a lot.
