It’ll take a while to knock someone out if you don’t really know what you’re doing. It might take even longer if you happen to be wearing these Giant Robot Battle Fists on both hands. Unless you’re the Hulk or Bizarro. That’s just as well, because they weren’t made for use in fights in the first place anyway.
They’re great for cosplays (Mega Man, anyone?) and for costumes. For costume ideas for comic book characters or other popular tv characters you can check out a popular costumes site. And with Halloween coming up in just a few weeks, you can kiss your costume woes goodbye. ThinkGeek says they’re forged from Cobalt Flame and Robotonium, but we all know better. They’ll ship out flattened, of course, but just pump in some air (or blow some in if you feel like showing off) and you’ll be good to go.
