Krillin vs Wonderman

Wonderman vs Krillin. Anime fts are accepted here since Krillin doesn't have a lot of manga time.

Krillin.

Faster, more versatile, powerful ranged attacks.

Don't think versatility decides all fights.

Sure it doesn't. But it's not Krillin's only advantage.

Destructo disc spam should take care of Simon.

Also iirc in the manga, Goku and Krillin were pushing around a 600 ton boulder.)They pushed it in the anime, but it was given a weight in the manga I believe) Which would put adult Krillin easily in the strength range to knock Simon around since

A - Simon's not fast enough to hit him
B - Simon's not fast enough to react to Krillin
C - That single feat as a child puts him solidly in the Class 100 range, and he's grown a whole lot stronger despite not having feats aside from fighting guys who outclass the Saiyans, much less him.

So Krillin is faster, durable/strong enough to take it to a brawl if it comes to that, and has plenty of energy attacks to give Simon fits, plenty to hurt him, and at least one that will outright kill him.

Yeah, Krillin's strength is not to be underestimated.

And Wonderman needed jet pack (or whatever it was) for one of his best str. feats. Something that he longer carries and his natural flight leaves much to be desired.
