Creeper src

Jack Ryder had appeared several times as himself in Batman Animated Series, often about him news reading about Batman's latest exploits.

In the episode "Beware the Creeper!" He became his current alias. During an investigatory segment about the Joker at the Ace Chemical Plant where his creation took place, reporter Jack Ryder and his crew were attacked by the Clown Prince of Crime himself. Ryder was exposed to Joker Venom and thrown into a vat of chemicals. As the factory around him exploded, Ryder was sucked away into the discharge system and drifted into the sewers. Deformed both physically and mentally, Ryder, now a yellow skinned madman, swore revenge on the Joker stating he would "fight fire with fire". While going on an insane chase through various Joker henchmen and Batman himself, in the end Batman apprehended the Joker, sedated Ryder and developed a dermal application drug to revert his changes. Fearing his career in shambles, Batman points out no one else is aware of the Creeper's identity and should remain so as long as he continues to wear his skin patch. Deciding he enjoyed the rush of power, Ryder subsequently removed the patch.

Ryder later joined the Justice League after the Thanagarian invasion, in the Justice League Unlimted episode, "Panic in The Skys". In the last episode of the series "Doomsday", he helped Hawk and Dove defend Coast City from Apokolips Warriors.In the same the episode Hawk, Dove and himself ran down the steps of Justice League base to capture Lex's team of supervillians.


  • Transformation: Due to a mixture of Joker's laughing gas and various industrial chemicals, Ryder's physiology has been augmented. His skin is now a sickly yellow and his hair green.[1]
    • Superhuman Strength: Creeper possesses substantial physical strength enough he could even knock Batman aside with a single backhand.
      • Super-Leaping: With his considerable strength applied to his leg muscles, The Creeper can leap substantial heights or distances; from building to building or off tall structures to land directly on people.[1]
    • Superhuman Agility: Creeper can effortlessly navigate and balance himself across buildings and infrastructure with little signs of fatigue.
    • Superhuman Durability: While not indestructible, Creeper can withstand blunt force trauma without major sign of injury.
    • Accelerated Healing[1]



  • Mental Illness: In his Creeper form, Ryder's mental faculties become substantially inferior; to the point he begins exhibiting sporadic behavior, spontaneous laughter and decreased attention span. Though a small patch administering antidote could keep him in his normal form, the "Creeper" side could break out if Ryder lost concentration.
