Well, for those who don't know(which is a lot I'm sure except for DC fans) lol I think this guy Terry McGinnis would make a great addition or secret character in this game. Probably won't happen but he's the star in that show Batman Beyond, also appeared in the comics briefly as well as guest appearances in the JL, Static Shock and Zeta shows post Batman Beyond Series.

He's the next Batman in the future after/post Bruce Wayne era..

To read more about this character, go here:

I think Terry's awesome personally and with his high tech gadgets, fighting skills and training under Bruce I'd love to see him fight some MK characters. His style is unique and different then Bruce's, he prefers to leap, jump often and turtle then attack in his fights as oppose to Bruce who is more in your face. Terry also uses occassional humor at times, Bruce doesn't and is "dead serious" 99% of the time. Read this, you'll find that Terry has a lot in common with Bruce in more ways then one....

As for Bizarro, well there's a few different versions but here's his wiki:

I think it would be interesting to see him because how how he's different in terms of where he gets his powers from as oppose to Superman:
