Flamewarrior11 asked: Is there a version of Ben 10 where he lives in the Yu-Gi-Oh and he has a special duel disk?

Professor Mark: That version of Ben is as real as the one where Ben lives in the SAO universe, and must get the Keyblade so they can kill Skeletron Prime, and then sail the One Piece seas so he can arrive at the BOB tournament in GGO and fight Venom.

JohnathenYoungs asked: Does Professor Paradox know Clockwork (Danny Phantom) and other time travelers?

Professor Mark: I do not know if the original knows, but there is an alternate version of Paradox who has met Clockwork, and had a Time War that also included billions of Time Travelers, even including Dr. Who.

JohnathenYoungs also asked: How strong would a fusion of Goku, Super Man, Danny Phantom, and Steven Universe be?

Professor Mark: A fusion like that would be really powerful, since it would have the strength and abilities of Goku and Super Man, and also not being able to be affected by physical attacks due to Danny Phantom's powers, and Steven Universe's shield for more protection. And due to also having the Omnitrix from Ben 10, the fusion would have hundreds of alien powers at their disposal, including the omnipotence of a Celetialsapien (Alien X's Species).
