Michael Owen Rosenbaum is the name. Much known for his role in Smallville as Clark Kent's childhood friend and archenemy for life...
Rosenbaum also did the voice for Wally West in the animated series of Justice League (2001–04) and its sequel Justice League Unlimited.
One of the rare few who "crossover-ed", his role as Martinex in GOTG II standing beside Stallone was rather missed out by many.
Or have you even noticed?
