You are the Master of Sex in the multiverse, you have a multitude of powers that all involve sex. Basically, you're sick of all these Disney princesses, Cartoon Network gals, etc. being squeaky clean and without some super cool dude/gal to give em' some cock/pussy.
So you're on a mission to travel from dimension to dimension, collecting cartoon gals from all of history, to create the biggest harem in history! You can manipulate elements from their world to turn against them and convert them into cute sex slaves.
Of course the girls won't be so game to you coming on to them like this, some of them even have super powers (Super Girl, Wonder Woman, the Crystal Gems etc ) so you have to use mind control and hypnosis to convince them to join your harem. I will play all the girls ^///^
