To go along with "Ambushed" here's Red X, Blackfire and Slade as good guys. I'll have to do a second one of Slade by himself so I can submit it to a contest.

Here's the other one, with descriptions and stuff.

Actually, here're the descriptions for these guys, But you should go read about the evil Titans too.

Slade - Dark vigilante and long-time protector of Jump City, he is very unhappy with the Titans recent move into his territory. Finding the teens more a challenge than he thought, Slade has enlisted the help of the Hive kids(heroes in training) and Red X.

Red X - Once a normal boy who desperately wished to help his city, Red X got his chance when he managed to steal a prototype suit Robin had created for himself. Red X found training at Slade’s side and now works to rid Jump City of its new terrorists.

Blackfire - Always tormented by the memory of her sister’s unwilling sacrifice, Blackfire set out across the galaxy to find her lost sibling and make amends. After tracking Starfire to earth, Blackfire found her sister changed for the worst. Blackfire blames her family and herself for Starfire’s evil, and eventually teams up with Red X, hoping to find redemption for herself and her sister.
