I haven’t dug much into the comics, but just based off the show; does anybody think Bulletproof is a genetically modified human, with viltrumite genes? The thought behind this is that he’s wearing the suit Mark tried on first, and seems to display Invincibles powers, as well being secretive about his abilities. I also think Bulletproof is a little on the nose, filler for invincible so to speak. Cecil would also want insurance against Mark, as we see him collecting different tools to fight Invincible if he turns out like Omni-man. Interested in your thoughts, thanks everybody!
