Ravage

Ravage is a Decepticon and one of Soundwave's pets. He is initially launched from Soundwave's back as a missile. He has one glowing red eye, two pointy ears on the back of his head, a razor-sharp mane, and a claw on the tip of his tail. His physiology is vaguely cougar-like.

Transformers: Revenge of the Fallen
When Soundwave learns of the location of the Allspark shard, he dispatches Ravage to find and retrieve it. Ravage makes it to Diego Garcia and deploys his microcons to get it while he holds off the NEST forces. Ravage successfully gets the Allspark shard and meets up with the Constructicons who use it to revive Megatron. Meanwhile in Egypt, Ravage searches for Sam during the final battle. As Bumblebee fights Rampage, Ravage jumps on his back to help his fellow Decepticon, but the Autobot grabs his tail, strips his entire upper body from his spine, and proceeds to beat Rampage to death with his other half.

Near the end of Season 2, Ravage was sent to prehistoric Earth in a transwarp cruiser to capture Megatron. With the help of Tarantulas, they succeeded in capturing him, but he used a fragment of the Golden Disk to reveal that he was following the original Megatron's orders all along. From here, Ravage joined the Predacons and attacked the Maximals, but was killed when Rattrap planted bombs on Tarantulas to blow up his ship. All that remained was his lifeless head, which (at the beginning of Season 3) was kicked into the river by one of Tarantulas's spider drones.

He also made apperances in the classic cartoon of the Transformers. He made more apperances than any other of Soundwave's cassette troops.
