Rex Splode is a character in the animated and comic book series, Invincible. As a child, he was taken away and enhanced with the ability to change molecules to make any object explosive. In the beginning, he is Atom Eve’s boyfriend, but it’s an unhappy relationship. She breaks up with Rex after she catches him cheating with DupliKate. He has a pretty intolerable personality, and rightfully gets put in his place by Monster Girl. However, they make amends and form a friendship, to which Robot thinks they are flirting — thus using Rex’s DNA to emulate a human form. Creepy. Jason Mantzoukas, who has made appearances in various NBC sitcoms such as The Good Place, Brooklyn Nine-Nine, and Parks and Rec, voices this character in the show now streaming on Amazon Prime.
