Battles

Both are bloodlusted.

No morals.

Janemba can't warp reality and Maj-Uub can't turn Janemba into a snack.

Fight takes place in Hell.

Majuub should have this in the bag pretty easily, regardless of whether or not Janemba can reality warp.

Majuub easiliy. Uub was holding his own against Goku at the beginning of GT and we all know that its painfully clear that Goku GT>>>>>>>>>>>>Goku Z. Uub later went to train in the mountains when Baby first arived and when they briefly fought he was hanging in there, considering Baby Vegeta was tossing Kid Goku SSJ3 around like nothing at his First Form noless. Uub basicly had a low/mid tier SSJ3 powerboost from Fat Buu to his own. Majuub became even a little stronger at the very end of GT. Janemba was being hurt a little by Goku SSJ3 and GT>>>>>>>>Z in terms of power so Majuub takes this one easily. Anybody actually from GT for that matter, GT villains/heroes are so much stronger than Z villians/heroes its not even funny.

@Sonata: The way i see it yes. Its similair how Gohan was weaker not just in power but in fighting skill when he was fighting with Darbura. His Mystic Power could have faded away after years of not training, otherwise, during the battle against Buutenks he could have gone SSJ2 and beat him into the ground, yet in GT we see him going SS2, even in the movie against Hirudegarn we see Goku/Goten/Gohan all standing beside eachother and you see Goku and Goten transforming into SSJ and Gohan just gets he white aura. Gohan turning SSJ in GT to me shows that he lost his Mystic Power/Hidden Potential otherwise like is said he could/should turned into an SSJ in DBZ. Or......DBZ Plothole 58362394 :)

@taichokage: Yes Janemba is actually alot stronger than people think, when Gogeta came to be he flipped out and he was powering up but Gogeta rushed him and you see Janemba stopping and then gets a beatdown, so its clear he wasn't fighting at his very best, maybe his powerup was large or maybe very little but still. I think Janemba could be around Super Buu maybe little weaker when he was fighting Goku at first and maybe when he's Full Power he could be around when Super Buu absorbed Piccolo/Goten/Trunks (Not Buutenks), as i think Buutenks would clobber him.

GT is just a mess if we take powerlevels, when Goku went to fight Baby Vegeta in his base form nonetheless he was losing badly, then Goku wnet SSJ3 and still did not much against Baby, then Baby transformed 2 times and ended Goku. Uub however was able to launch Super Baby into the wall and actually hurting him a litte, something SSJ3 could not do (plothole 7462136), give Uub the powers of Fat Buu then you got a monster, and considering Uub is pretty serious about his training i don't see as why he would't keep training the whole time up until the end of GT. I still think Majuub is to much for Janemba.
