If lava prick had magmed ma boy koby

[Warmmedown]

would Garp have killed him

 

[SSJ2]

Helmeppo one shots him.

 

[Warmmedown]

I mean when Akainu was about to kill Coby at Marineford. The event that spurred Helmeppo's progression from scrub to rivalling isaac moon jr.

 

[SSJ2]

Yeah, Helmeppo would get the biggest rage boost ever seen.

Garp would have probably been struck down by Sengoku again. He'd probably try though.
