Jack Palance (or simply Jack), was a big aggressive male T. rex (probably the name was unmentioned in the episode) who won the first battle with Stumpy and the main antagonist of "End Game". He later attacked and canniballistically killed his rivals young after they strayed to far from their parents. He also tried to take a Triceratops carcass from his enemies, but after a fight, the two T. rexs pushed him down and he was skewered on the horn of the Triceratops. He was greyish-brown with white pits and divots on his skull.


  • It is unknown if Jack is the T. rex's real name, or if it's just a fan made name for him. But it possible that he's real
  • Although the main antagonist, his role was small.
