The comic starts with this guy and a woman kissing, then his girlfriend or wife comes and catches them in the act. She starts fighting the guy with superpowers (her powers are blue and look cool as heck) and then at the end of the fight after killing the guy, she transforms into this phoenix type form (similar appearance to Phoenix from X-Men) and flies away. She had blue hair. Read it in 2003 -2004 give or take, it's comic like and it was drawn in color. I think it's target audience leaned more towards adults. Anybody have a clue? It's been driving me kinda crazy. That’s all I remember but the graphics of the comic looked futuristic.
