Devastator is a tormented being, his very formation wracking his component Constructicons with pain and stressing them to the breaking point both physically and mentally. The imperfect fusion process produces a mind that's very much less than the sum of its parts; rage and pain are all he knows, pushing aside whatever intelligence he might possess. Devastator relies on almost pure instinct in battle.
Devastator is named after Cybertron's unwithstandable and terrifyingly destructive Devastator Winds, due to his intimidating strength. Devastator can also create powerful gravity wells by generating an artificial black hole with his Vortex Grinder, located in his mouth. Nearby objects are drawn into his gaping mouth to be crushed.
When Straga was killed the tower was beginning to be destroyed, but Devastator kept the tower at bay long enough for Gumball and his friends to escape killing Devastator in the process. He was got back to life by a Big cup of venom.
