Kill Deadpool, marry Sailor Mars (or civilian name: Rei) because she's kind and sweet while being fierce, then have sex with Homura Akemi (because she's beautiful).
Harry Potter time!
Harry Potter, Bellatrix Lestrange, and Aberforth Dumbledore (the goat-loving brother)
I'd kill Potter, then have sex with Bellatrix and marry Aberforth but the choice is up to you.
