Super Janemba beats Buuhan or Kid Buu

Hell I’ll say it. Movie 12 SS3 Kakarot beats Buuhan and Kid Buu. Kid Buu is stronger than Buuhan.

Fat Janemba is above Super Buu. We don’t know by how much.

Kakarot Japanese: I ain’t ever felt a ki like that before.

Kakarot English: Incredible. He’s stronger than I thought. We were right to call the fight off. This guy could destroy the whole universe. I’ve never felt a power like this! Hey, if you don’t mind I think I’d better handle this one myself.

Super Gotenks exists. So he has met and fought Super Buu. There’s no getting around that.

Buutenks is double Super Buu roughly.

Buuhan is not much higher than Buutenks. Less than double Gohan.

Fat Janemba would put up a fight with Buutenks. About the same as Ultimate Gohan, maybe more.

SS3 Kakarot beat the hell out of Fat Janemba.

So M12 SS3 Kakarot would beat the hell out of Ultimate Gohan from Z Anime Fusion Saga since Ultimate Gohan can’t beat Buutenks and was only a little competitive at the beginning, for the most part. It wouldn't be much different to SS3 Kakarot VS Fat Janemba.
Like SS3 Kakarot VS Super Janemba, the difference became apparent very quickly. He was done after the mouth blast.

The rest was struggling to hang on and put up a fight. The sword is a cop out argument. Janemba certainly didn’t need it. He slowly appeared before a heavily damaged SS3 Kakarot from the mouth blast, taking his time picking up the sword. And he’d use the sword against Buuhan anyway so it’s a non issue. It still hurts Buuhan and drains him mentally to regenerate over and over again in succession which drains him spiritually or energetically too which lowers his power level.

Z Anime SS3 Kakarot was said, before fusing, when Buu absorbed Gohan, it is said SS3 Kakarot is on par with Ultimate Gohan…this picture.

This SS3 Kakarot in M12, is stronger than Z Anime SS3 Kakarot and would clobber Ultimate Gohan.

Kid Buu is stronger than Buuhan.

SS3 Kakarot in Z Anime can't beat Kid Buu. But he would put up a better fight against Buuhan than he did with Kid Buu.

M12 SS3 Kakarot is stronger than Fat Janemba. Fat Janemba would compete with Buutenks.
SS3 Kakarot clobbered Fat Janemba.

While Z Anime SS3 Kakarot is on par with Ultimate Gohan and can't beat Buutenks.

So M12 SS3 Kakarot would put up a better fight with Kid Buu than the Z Anime Kakarot did. Not to mention, he doesn't have a physical body. He'd probably be capable of wiping out Kid Buu with an Ultimate Kamehameha or Shin/True Kamehameha in this form. With no physical body.

Kid Buu is stronger than Buuhan.

Meanwhile, Super Janemba beat M12 SS3 Kakarot easily.

Super Janemba is in a whole different league to SS3 Kakarot. He didn't even power up yet, and easily won.

Super Janemba powered up twice before fighting Gogeta.

Super Janemba, before powering up. would beat Kid Buu. Period.

Again, Kid Buu is stronger than Buuhan. All the authors say so. The narrator says so. The characters say so. The manga even says so. And the DBZ manga and anime go together anyway. Toriyama said so.

Potara was desperately desired. Crushing them was a mistake. They said so in the anime.

Ultimate Gohan was ON PAR with SS3 Kakarot, before fusion. Kid Buu VS SS3 Kakarot, is a stronger SS3 Kakarot, than the SS3 Kakarot that fought with Buutenks. Much stronger.

Toriyama about the anime and manga going together in one dimension, together in continuity.

So Super Janemba beating Buuhan and even Kid Buu is no question. TOEI knows what they're doing. TOEI are the same company that make it very very clear, in Super Dragon Ball Heroes, that the Future Trunks of DBZ, which is the Time Patroller Trunks, and the Future Trunks of DBS, are two different Future Trunks from a DBZ timeline and a DBS timeline.

And M12 SS3 Kakarot is capable of gathering enough energy to go all out with an Ultimate Kamehameha and annihilate Kid Buu, like he tried to do in the Z Anime or it might've been a Super Dragon Fist he was going for, but with a physical body, it was too taxing.
Without one, he can. And he's stronger than the Z Anime SS3 Kakarot to begin with, BUT also doesn't have a physical body.

So, Super Janemba beats Buuhan and Kid Buu. Probably without needing to power up. The same one that beat SS3 Kakarot, he'd beat Buuhan and Kid Buu. M12 is a different league.
