Did this when I first did digital stuff.
Carnosaur is Raptor's prehistoric brother. Back in the Cretaceous Carnosaur was abducted by aliens called Slashers and experimented on him keeping him alive for 65 million years. Finally done with him left him on the moon till Area 51 found him and took him to base. They learned that a smoke dinosaur is also living inside him sleeping(which is why he stayed alive in space, regeneration)Carnosaur escaped and ended up in Africa where Sierra found him and took care of him Raptor learns he's alive and searches for him. Mighty Joe Young goes to this story,

Extra: Carnosaur is a T-rex, Velociraptor and a Carnotaurs mixed. Carnosaurus Raptor, created in 2006. My brother hates Jurassic World because he feels that they stole his idea with the I-rex cause almost everything it does is what Carnosaur does.
Sierra is based off Violet Parr from the Incredibles
