Wiccan and Hulkling because they are boyfriends))) Aside from them Jean Grey and Storm, Mistique and Sabertooth maybe, Deadpool and Spider-man, Loki and Dr. Doom (I know that Doom probably is not a better variant but), current Captain Marvel and Spider-woman, Gambit and Black Cat (both thieves).
Awesome, man! I`d love to see Lobo in all his gore glory. So few can do him justice. Could pair him up with Kitty Pryde for the Brute/Subtlety contrast. But Hell, I would love the sh*t out of Lobo alone.;];]
