@solesamurai: Dexter is not only younger but has created things similar to Doom such time travel.
Also Dexter in the future can create anything just by a thought IIRC.
Dexter stated he could create universal level devices.
Has doom created time machines when he was a 8 year old kid?
Also AJ from Fairly Odd parents created a time machine from string in seconds...that's a feat Doom can't compete with...
Dexter has a machine that gives him infinite knowledge.
How is any of that comparable to becoming Omnipotent with literally a few hours of prep before hand? Doom had very little time to do what he did and he has done it multiple times. Dexter has never become Omniscient IIRC you're talking about that machine that he put on his head and it gave him super powers right? because he didn't have infinite knowledge. Unless you're talking about something else. I don't remember AJ ever being that smart need proof, Dexter creating stuff with his head isn't an intelligence feat it's likely reality warping. Not to mention none of the stuff you said was prep feats, all of it was basically them showing high intelligence most of which is assisted by toon force and not their own intelligence. It is impossible to create anything other than knots with string that is impeccable toon force not intelligence.
