Literally him tanking a punch from Goku and his insides not melting
Dude, literally NLF. Why hasn't Luffy just LUCKED his way through every fight? Why didn't Kaidou die of a heart attack? Wouldve been lucky right? That ain't how this works.
Raditz can nullify his own attacks, read the ki page.
Also Luffy can't, the attacks are like 100x stronger than him or anything he's reflected. It'd disintegrate him and the rubber he uses to deflect it.
Uh, the fact he just isn't? He's an asshole, but like not any worse compared to Vegeta, and I'm sure as wel all know, Vegeta wasn't PURE evil. Now he sure as hell ain't good, dude murdered for fun, but so does Teach, or a lot of OP dudes really. Hell Raditz just kind of doing his job.
So Gear 5?
