Let's see how they stack up:
1. John Dragon Ball
He's keeping it 1000, he has SSJ and he can copy DB techniques. He's the Last Son of Toriyama. Enough said.
2. John Kaisen
He's one of the Jujutsu sorcerers of all time; they say when he was born the balance of power stayed the same. He wields the Two Eyes and Limited. He could match John Zenin in battle and even defeated the legendary Grade 3 curse, and all of this isn't taking into account his Domain Expansion: Dreaming of Getting One
"P is for Priceless, the look upon your faces,
E is for extinction, all your puny races,
R for rrrrRevolution, which will be televised,
F is for how F*cked you are, now allow me to reprise...
E is for Eccentric, just listen to my song,
C is for completion that I've waited for so long!
T is for the terror upon you I'll bestow...
My name is Perfect Cell, and I'd like to say Hello." ~Mr. Perfect Cell
