In games, there's sometimes a character whose the same as you in every way except they try to be better than you. They are generally evil and are just as strong as you if not stronger. So whose you're favorite?
Mine is Dark Samus from the Metroid Prime series because it isn't just a made up alter ego, it's an alter ego that has a back story. It started out as the Metroid Prime but right before it died, it stole Samus's phazon suit and was reborn as Dark Samus.
In the second game, It was gathering enough power for the third game where it became an actual final boss.
So what's yours?
