JManM
A thought occurs, what if, somehow, grunt gains full control over his mighty dimensional coitus powers, and then everyworld he has been to suddenly all slam together into one universe, what kinda chaos would that look like, it could aslo serve as an amazing lemon chapter location, let me know what you think? Have a meme too.
Avoid anime worlds if at all possible. By the time he's done with the MCU, Grunt will have been more powerful than most anime worlds. Remember, by MCU rules Grunt can bring the Infinity Stones with him when he goes to other universes. He won't be able to use their special abilities, but he will be able to use them as a power source if by eating Laufey he counts as a local entity in Laufey's universe. Most shounen anime worlds are all about chuuni morons trying to look cool and only succeeding at it because of the medium. The only one that might be worth it is Dragon Ball Super (for the insane power-up potential) and any anime world that has a waifu that you really want to bring along. Of course, something else you can do for anime worlds is to have Grunt and Jack go on a drunken bender and absolutely wreck every post-DBZ anime world in the course of one chapter. That's about all the space they deserve.
