Sorry but what kind of hax are u talking about? Seems like you are saying that every single hax can solos S8/BC/Marvel verse...ehm, wut?
I mean, let's take for example S8...just Ata's clone has:
• Massively faster than light speed (reached a galactic quadrant from another one in few hours while slashing into pieces asteroids)
• Immortality (they can only die if God Fudo Myo-o forsakes the samurai, if they admit their defeat)
• likely Planet level durability: Ata's clone bullrushed through a planetoid casually, without a scratch.
• Sub-atomic fast regeneration (unlimited unless you can counter sub-atomic regen. or if Fudo Myo-o forsakes the samurai)
• Digital consciousness and cybernetic body and soul. Samurai can also live without their souls.
• Moon to planet attack potency: Ata's clone casually cut in half the moon with a single swing of his sword. Daruma also shown that Ata can destroy planets.
• His attacks can reach thousands of km. distance/damage area. Just like he did to the moon with one swing of his blade.
• sorta time control attacks: Kongo-Yasha style Samurai can set the time between the swing of their swords and the eventual cut on their targets.
• let alone every other power ups like Spaceship holders, Samurai armours and those floating soul orbs...
...How can someone massively slower, weaker, fragile etc. than him...win? Even with "hax".
If you are a common human but you have "hax" then this doesn't mean you can kill i dunno...Doomsday or Hulk. He is faster, stronger, far more durable than you! Let alone regeneration. You can't even perceive them, they are too fast. How could you hit something you can't even perceive?
