Rex would be introduced into mainstream comics as a member of Prof. Pyg's Circus of Strange. After fellow freak Mister Toad was apprehended by the Gotham City Police Department, Rex and a couple more members of the Circus of Strange were dispatched to seemingly rescue Toad. During their attempt, Rex was defeated and arrested by a new Batman.

Powers and Abilities

  • Flames: Rex body is shrouded with lethal flames but not to the user it seems. It is unknown if the flames are natural or artificial.

In other media

  • Batman: Arkham Knight: Phosphorus Rex is mentioned by Professor Pyg as a member of the Circus of Strange in Valentin's advertisement for the show. In a poster for the Circus, it implies that rather being a meta-human with fiery powers that he is instead simply a, "fire-breathing/eating" performer.
