Patch is a large tarbosaurus male that was the protagonist of Tarbosaurus the mightiest ever. He is first seen as a hatchling. He lost his two siblings and was the only one who was able to reach sub adult. After his first kill, he was forced to live o his own. When he was an adult, he was able to survive on his own and claimed his own land.
He met a female tarbosaurus, who was Speckles mother. Patch was forced to fight a rival male and he won the battle. As time went on, he had two children before a therizinosaurus killed them. Patch was able to kill it, but he sadly died from the injuries shortly after he broke up with Speckle's mother and his corpse was presumably scavenged by the waiting velociraptors.
