Titus vs The xmen
Titus is a pretty powerful foe and he single handly took out the team of jla. The thing about titus is that during that time he was affected by a volt of electricity from batman that hurt him and he again was hurt by batman with some grenades to the chest. I know that the jla consist of great and powerful foes but the jla lack at things that the xmen have.
The team consist of
Storm
Magneto
Wolverine
Colossus
Classic rogue
Cyclops
Mimic
Rachel Summer (current)
Cable (godlike)
Cannonball
Blink
Havok (the one that fought vulcan)
