Big Red

Big Red is an unnamed Autobot from the Generation 1 universe.

Big Red is big and he's red, and he can grab you out of the sky if he wants to. He doesn't have a real name, but people call him Big Red. There is an Autobot who looks just like Big Red only he's yellow and his name is either Tempest or Pulsar. But we don't care about him because Big Red is red and he's awesome.
