Each episode slowly transforms The Flash into a rip-off of The X-Men down to Professor X's high-tech wheel-chair. Come on! When did Colossus become a villain in DC Comics? Previously, they had Gambit become a girl in Plastique. They even hinted on having Human Torch. I would not be surprised if DC resurrects Wolverine in the future as part of their universe.
DC and Marvel have had copycat characters for decades now. This is nothing new.
