I probably already stated whom of which is my favorite.
Barry Burton. He got offed by zombies/hunters/chimeras, blown up, saved Jill via helicopter mere months later, survived the Gameboy Color, got rebooted, endured a WS Anderson film, and then saved the day by killing another Wesker, rescuing his Daughter, and adding Cutscene Powers to his already granted Plot Armor.
Also, he's a Mercenary. And he's REALLY good at one-liners and other commentary. And he's damn good at sandwiches.
