Scourge is the leader of Jungle Planet and former antagonist-turned-hero from Transformers: Cybertron. He has relationships with Lori Jiménez, because he calls her a little sister.
When Scourge met Megatron, he tried to trick him into giving him the Jungle Planet's Cyber Planet Key. But when Optimus Prime and Leobreaker beat him, he gave it to them and their friends. He later went with Megatron and helped him defeat the Autobots and enslave the universe. But when the Jungle Planet was in danger of being absorbed into the black hole, he and Snarl went there to help all its residents. Later, Leobreaker arrived there and helped to evacuate it, and then he and his people helped defeat Galvatron. And finally, he and other Transformers defeated Galvatron, destroyed the black hole and saved the universe. And then he competed for the position of the leader of the Jungle Planet with Leobreaker, and he won. And then he and Snarl did their best to protect their planet.
