Yhwach is known as one of the most powerful Bleach villains out there. He’s definitely not someone to be taken lightly but Bass is still more than a match for him. His powers are basically limitless and it won’t matter that Yhwach can see the future. All he will be seeing in the end is his own defeat and that’s just not going to help him in the end. Bass wins.
Leonica is someone who always braves the unkown and will do her best to slay impossible foes. It just won’t be nearly enough to do anything against someone as formidable as Bass. Bass is the strongest being in all media. There is no one who can really challenge him and while her sword skills are powerful, they would not be able to break his barrier. His FTL speed would also ensure that there is no way for her to dodge his attacks for long. Bass wins.
Gilzea is the ultimate dragon fighter of darkness. He can beat anyone in a single move and moves with such speed that nobody can even react to him. It’s all very impressive so naturally I had to put this guy up against the true strongest of all media. As intimidating as Gilzea is, Bass is much more formidable still. A single Darkness Overload would deal a ton of damage and Bass can beat him in close quarters combat without any real trouble. Bass wins.
Tenchi Masaki is supposed to be really powerful but I can tell you that he would not want to have to fight Bass. Bass is in a completely different league and his power is overwhelming. Tenchi would be on the back foot here and it would be difficult to try and get much farther. Any and all attacks he use could be easily blocked and reflected by Bass. The difference in sheer ability here is just much too great. Bass wins.
Ainz Ooal Gown is one of the stronger main characters out there as his stats were maxed out right from the start. He could give many fighters a run for their money but not Bass. Bass is still known as the ultimate character in media for good reason. He never surrenders and never backs down. His power is absolute and a few Darkness Overloads will end this. Ainz Ooal Gown may not expect that he would lose to darkness, but such is the irony of power. Bass wins.
Ardyn Izunia has a lot of good teleportation/speed feats at his disposal so he’s a tough guy to defeat for most opponents. That said, he still won’t be doing anything against Bass. Bass can block or absorb just about every attack that he’s got. Ardyn has no real way to put Bass down as one good Earthbreaker could easily end this. Bass is just way too powerful to be defeated and he will claim victory in record time. There’s a reason that he’s at the top. Bass wins.
Anos is back but he’s definitely not ready to be going up against someone like Bass directly. Bass has powers and abilities beyond what Anos can even dream of. Pure destruction simply isn’t enough to phase him. Bass has the Get Ability program which can reflect damage and he also has speed on a level that’s completely unheard of. It’s hard to see Anos being able to last very long here but at least he’ll finally have met a worthy opponent. Bass wins.
Kaido’s whole reputation is that he is the absolute strongest in the verse. Land, Sea, or Air, always bet on Kaido. That’s just how it’s always been but if you take him out of the One Piece universe I dare say that Bass could teach him a thing or two. For starters, Bass is much faster than Kaido. He could run rings around the guy with ease and also has enough destructive power to put Kaido down. When you add all of that together, it means that Kaido doesn’t stand a chance here. He can’t dodge any attacks nor can he endure them. At the end of the day that means it is curtains for him. Bass wins.
Suggested by Dinosaurroars Lucifer Magne is a demon who likely has a ton of power. Based purely on his standing and reputation you could come to no other conclusion but at the moment he hasn’t shown me any kind of ability that would put fear into Bass. Bass is massively faster than light and had enough power to take down Hubstyle Megaman. These stats mean that he could put an end to Lucifer in an instant. Bass wins.
Suggested by Dinosaurroars Alastor (Hazbin Hotel) has some fairly powerful demonic abilities. He can use fire, strength, speed, and a whole onslaught of other abilities to get his way. That definitely makes him someone to be feared for most fighters but not Bass. Bass is the strongest fighter we’ve ever seen. His sheer power and speed are completely off the charts to the point where it’s just hard to see anyone being able to put up a good fight against him. Alastor wouldn’t have time to prep any attacks before Bass just barrels into him. Bass wins.
