Do tell;

Zanhar: black magic

Riku: Hawking, but with a killer cockatoo

8theBabe: sheer perfection

Prez: jk he can't kill anything, not even himself

Wanta: will make riku do it

Well, let's see:

Zanhar: Throwing Fireballs o any kind of Dark Spells in general (AVADA KEDAVRA IS 100% GUARANTEED).

Mauser: I'll agree with the Pitch Forks.

Slim: A blow por Judge Judy's stolen Gavel.

Riku: A Trumpet arrangement of Death.

Blind: Either a Sword o a cuchillo Stab. Perhaps, lots of the later.

SilentForce: Teleportation into Outer Space. Throwing people inside Black Holes?

CokeTheUmbreon: Dark Pulse.

Catslover: Slicing up por using his Claws. Duh!

Candylover: Sand Burial.

Zeppie: For some reason, I think a cuchillo Stab could work for her as well.

SwordofIzanami: To put it in Zanhar's words ''Firing teh lazas''. Lots of them. I could see him using a giant Sword as well though indeed.

8theGreat: Displaying overly cute things.

DisneyPrince: He is a Gentleman so he wouldn't kill. If I had to say something, I can't t help but imagine him using a Scythe.

I will add for others as well if I can think más !!!!

Mauser : * rifle blowing heads

Riku : surround the victims with 1000 baby cockatiels,let them die from too much cuteness


zan : slit throats using silver dagger


Lefteris: play metal música with "guitar sword" then cut off people's heads with it


THaSlim : is busy tweeting judge judy

Alright...

Zanhar would probably do something from Avatar.

Riku would CLEARLY not kill you. She'd simply abduct tu and lock tu in her club.

Blind would lock tu in a room full of mind controlled Touhou characters

Lefteris would probably do a Monokuma style punishment.

All I got so far.

Zanny: fuego Nation, attack!

Lefteris: *sends a thunderbolt down*

AuratheLucario: Aura Sphere!

*will add más later. I have a crash*

Zeppie would murder someone with the backside of a hedgehog. Just straight up stab em.

Wanta: He would get me to do it

Lefteris: Some magical Kung Fu of Justice

Prez: Super Weed them to death

Mauser: Gun duh

8theGreat: Kill them por putting them in Lolita costumes 200x too small for them till they choke

Blind: Death Glare

Zanhar: Some dark evil shit o something

CatsLover: Uh... Summon the gatos and hope the guy is horrifically allergic to cats

Zeppie: Subtle backstab.

I'm on mobile so won't type many

Riku: cuddles her victims until they suffocate
Ego: summons his army of mice to swarm the enemy
Blind: headbutt. Like death glare into skull cracking headbutt.
Zanhar: avada kedavra
Jim: too high to murder. Will plan intricate jigsaw style traps but eat pizza instead
Lefteris: it'ssss punishment timeee!
Mauser: gun show
Coke: slaughter por Pokemon
Wanta: poison their soda
PrincesTale: uses book collection to inflict death por papercuts.
8: stabby pens
Catslover: a trap that gets a person to walk closer to a cute cat then trip wire, cage falls on person. Death por starvation.
