Round 1 (Both standard form)
Round 2 (Alternate Future Him vs Full Power Aku)
I know this is not anime but this fight seems so epic
Aku because I'm under the impression that him doesn't have the ability to time travel.
No HIM dose not have TT but he had enough TK to move the sun with 1 hand also full power HIM was able to take over the CN earth (which includes Dexter,KND,Billy and Mandy,Ed Edd and Eddy and maybe Johnny Bravo and Courage) HIM would have not fought anyone from Samurai Jack seeing that is a another alternate timeline.
Dudes Him is pretty much Satan. He's able to infiltrate the girls dreams and give them the worst nightmares of their entire lives. Hell on the girls birthday party he was able to possess them and Professor Utonium. Not a single person noticed a thing. I mean not one damn thing. Him stomps.
Him wins. He's simply too powerful. In fact, whenever he is in direct combat with the Powerpuff Girls, he is never truly injured and only seems to let them hit him etc. Him usually schemes and plots, never really fighting them head on. Let's not forget that Him was the one who gave the Rowdy Rough Boys more power. And Him effortlessly moved the Sun during an argument with the other villains. Aku has never done anything that impressive.
Yeah... round 1 goes to Aku.
Round 2 for Him.
