Backstop

Backstop is a rhinoceros transforming Autobot and old teacher of Snarl and Scourge from Transformers: Cybertron.

History
When the future was feared, Backstop began to train a generation of peaceful warriors, and Snarl and Scourge were his best students. But when Snarl and Scourge left, the big wars began, and they marched with their armies, destroying all who opposed Scourge. Years later, Scourge made peace, but it was the tyranny of peace. When Overhaul arrived on the Jungle Planet and was injured, he rescued him. And after the presentation, Overhaul told him that he came looking for a Cyber Planet key to save the universe, and he had no reason to doubt his intentions. And as soon as Optimus Prime decided to face Scurge in battle, he told Scourge he was able to determine the time and place. And when Optimus beat Scourge, he gave him the Cyber Planet Key. And after Megatron became Galvatron and stole the Omega Lock goal to widen the black hole, he joined the fight against him with old students and other inhabitants of the Jungle Planet. And then when the black hole and Galvatron were destroyed, he joined the space bridge building team with Evac and Lugnutz.
