@Chef_Banchou: That depends on what you say is one-shot hax. Do you mean can't kill Mo-Ri in one hit? He's already faced characters that powerful before (Lee Soo-Jin 1st Crown Prince). But that's not all he can do. He has basically an amplified version of Full counter that extends ti physical attacks as well as energy attacks. He's punched a guy into space before and has some regeneration power. He also has anti-gravitational flight. I think Mo-Ri has him in durability but Kazuma can contend or perhaps exceed Mo-Ri in the others stats. Maybe Mo-Ri has greater raw strength but striking strength definitely not. Additionally, the "hax" move is just extreme raw power that causes the phenomenon of ripping a hole in space, much like Arc Gurren Lagann.
@Chef_Banchou: I don't have the scans, but Kazuma could bfr via a punch that distorts space, opening a hole in it and sending the opponent through the hole in space. HE also had the giant explosion fist which created an explosion around the size of a small moon. He can survive in space in the manga iirc too.
I think the issue if that it's literally too big. C4 wouldn't work most likely. This thing was caving in small mountains. with it's foot. Same with the portable lake jutsu (lol). The only thing I see working is Deidara's suicide move. But if the Mammoth inhaled just once, they'd be screwed. Even Toriko and Sunny could barely resist getting turned into bones.
I think your OP is a bit too flexible. Of course there are many that can.
Let me see. Perhaps Guyver, Kazuma or Ssj1 Goku (Android Saga) at the low end. I vaguely remember Guyver but I think those 3 with heavy effort could beat Mo-Ri.
P.S. I take it Manhwa is counted as anime/manga?
Saladking's trolling guys, he knows TOAA would be able to erase Chaos King. 10/10
As for Hitoshura, being capable of fighting YHVH and defeating Lucifer who created the Amala Multiverse to create and destroy countless entire universes in the time span of an eye blink should certainly be capable of overpowering Chaos King and sealing him in another isolated universe. That said he can't erase him
Eliminating the concept of nothingness is possible by making everything one, as in a singularity or 0 dimensional space. Completely possible for nigh omnipotents but not for Demi fiend.
@GrayWolf2: Maybe the beasts are faster? The sheer speed of the Battle Wolf and Mother Snake in particular have been hyped from the beginning. I'm not saying the Kings were definitely that fast but I mean, Buranchi was Mach 30,000 and his strength level is about equal to the Kings or a touch lower. I know he specializes in speed so for him it makes more sense, but it's quite clear he isn't capable of blitzing everyone. I know I'm talking top tier now but apparently, Joa can slice 100 million times in what looks like one slash (One Hundred Million Slice Fillet). Additionally, this isn't necessarily travel speed but blitz speed. It's known that the battle wolf can maintain it's maximum speed as elaborated in the Regal Mammoth arc. The Kings can't do that.
