Uhh...Weather Wizard isn't a peak human. He's a supervillain who can create and manipulate weather.
Who have to have a wand to do so
Sabretooth is a powerful mutant with an adamantium skeleton, healing factor, super strength and speed, sharp claws and teeth, etc.
Sorry peak mutant
You define those as peak humans only?
Yes, to Piccolo who can blow up the moon (they are)
Piccolo solos. He is too powerful. Even if he isn't a Super Saiyan, he's still more powerful than one. The fact that he fought evenly against Android 17 supports this since Super Saiyan Vegeta was unable to defeat the slightly weaker Android 18. And Piccolo only grew stronger as the series continued. Who knows how powerful he was at the end of DBZ. Nobody here will be withstanding energy blasts that can destroy celestial bodies. Piccolo is also too fast and I doubt that Weather Wizard's lightning will do much to Piccolo, especially since they were already tanking nukes all the way back in Dragon Ball before Raditz had even arrived. Piccolo is too powerful and too fast. He can blitz them all if he wanted to, he could destroy the planet if he wanted to as well.
@Newdeath: Yeah Piccolo became pretty beastly at the end of DBZ. After the fight againts 17 he went into the Time Chamber and when he came out Trunks/Vegeta/Goku all commented on how much powerfull he became and that was during the Cell saga. Hell if you include GT Piccolo, you see him putting badguys away in hell the whole time.
