Running a Supers! forum game

So I decided to give running a forum based game a shot, as I'm still meeting other gamers here in the Portland area. Set in the DCAU, the 3 heroes Doc Aeon, Ogre & Ricochet receive a mysterious text with a "?" as the sending address. It tells them to be at a certain bank in Gotham City at 2 PM the next day. Our heroes show up individually right before an armored car pulls up. Once 2 PM comes around, 3 villains, Quakemaster, Zebra Man & Blockbuster, all lesser foes of The Batman, attempt to rob the armored car of it's loot. We just started the combat phase, and Aeon all ready took 1D of damage from Quakemaster's jackhammer. Will our heroes prevail? Who sent the text that lead them to the bank? Hopefully, those answers will be forthcoming....
