now before u guys blurt out juggernaut in actuallity this is a fair fight let me list kazuma's feats:
kazuma like juggernaut has shown enough power to break though dimentions and time its self its not a skill either kazuma did it 2-3 times on accident just by unleasing his power
kazuma can fly and has been shown flying out side earths atmosphere and surviving suposivly due to so type of bubble created by his armor
one time while fighting a powerful enemy kazuma had two of his limb ripped off and a hole though his stomach all the while laughing at the pain and continued fighting showning a high tolerence to pain( let me say that ripping off kazuma's limbs in armored form is not an easy feat)
speed is on kazuma's side considering he has disappeared during flight(odviously not IT lol)
amazing feat: as posted above kazuma with his two limbs torn of limbs torn off opened a diemintion to the dinosaur age kazuma then created a blast(punch) that was so powerful in the comic it was said he was the thing that killed the dinosaurs then transported himself BACK to the present.
with that said this is a pretty even fight except kazuma loves to fight and often goes into berserk and considering kazuma doesnt have long range attacks he will attack juggs head on thinking he can beat him with is a disadvantage but kazuma power is = to juggs
1) juggernaut does not have the healing factor aka he is not invensible in this battle
2)juggernaut has the force field but can it stop kazuma?
3)fight to the death
