Was Just watching The season 9 again and was thinking that goku even at super saiyan 3 wasnt able to do shit to buu at that time,goku was running out of energy but kid buu was not showing any sign of running out of power,he kind of had unlimited potential,consider it energy based attacks or brute strength,but goku said he woudl've killed buu at beginning if he didnt fool around ,and kid buu had insane regeneration so does his regeneration keep restoring his power ?

if he has limitless power, he wouldn't need to sleep.

@kyrees: im just asking i dont know myself,goku went all out with his best attacks,but he destroyed almost 3 planets in less than hour without getting exhausted and he slept jus for a few mins ,goku woke him up

@youngman_logan96: kid buu has a high ki capacity. scouter readings on kid buu in one of the dragonball games reveal that he's at least 1 billion. while that data may not be canon, it's a high amount of power so he can literally do all that destruction and regeneration and restore himself instantly by just sleeping.

@kyrees: so his regeneration helps him ? even if he has fatigue toxins his regeneration might be getting rid of fatigue ,well these guys sure do destroy planets like its puncturing a football or something,destroy the planet ahh its easy lol

@youngman_logan96: i do not know if regeneration helps him but regeneration in dbz uses ki like it did to piccolo.

@kyrees: exactly here is what is diffrent,piccolo cannot instantly regenerate and piccolo cant regenerate if he is blown to pieces but this guy just doesnt run out of power,though i think you need something or someone stronger to kill him,but i guess his potential is virtually limitless

@youngman_logan96: kid buu isn't limitless. he just has a high ki capacity that he can do all that so easily. plus the fact that he practically restores his ki by sleeping given that he slept when goku and vegeta were arguing on who goes first to fight. if he didn't sleep at that moment, kid buu would actually have been more believable to have limitless potential.

@kyrees: i agree,i said virtually limitless,and that sleep of his was only 5 mins,that is why i said virtually limitless,i agree with you he is not having incalculable power but fast restoration and its insane to restore power at planet busting level in jus 5 mins

@youngman_logan96: If I recall right, the fat buu didn't show any signs of fatigue either. He just.. ran out of energy. Seems to be their system.

Fat buu also took a nap after he built his house.

Maybe..

@youngman_logan96:

Think of it like Captain America and his Super Solider serum. No Fatigue so he doesn't get tired difference is Kid buu and pin point all his tiredness per say intro what point and doesn't get tired across the match like other characters like Goku and Vegeta.

His regeneration allows him to always come back.He has unlimited Ki not stamina but it is high.Thats why SSJ3 Goku had a lot of trouble.Of course that transformation had a lot of strain but his regeneration keeps him in.You need to overload his regeneration to put him down for example:Kid Buu fighting Good Buu,Ultimate Gohan vs Super Buu,etc.
