Are you guys serious?
Flash can kill all 6 of these guys in less than a second.
I'm not even being biased or anything here, cuz I'd much rather see Marvel win, but they just don't stand a chance against Flash.
Even with Doom and Richard's prep time. I don't believe for one second that they could think of anyway at all to protect themselves from his onslaught.
As soon as the light turns green, the six will be dead before the green light even reaches their pupils.
