Devcon had been stationed on the Moon until Sentinel Prime activated a space bridge to Earth. Heeding the call of Megatron, he joined the Decepticon beachhead in Washington, D.C.. During the invasion of Chicago, Devcon participated in the initial strike and contributed to the mayhem. During the Autobots' attack on this Decepticon stronghold, he was one of the many Decepticons who fired upon the retreating Autobots. When the tide began to turn in the Autobots' favor, however, the behemoth met his end as he tried to hold a bridge. The Wreckers piled onto Devcon, shooting him in the head multiple times until he fell to the ground dead.
- Devcon will appear in Thomas and Twilight Sparkle's Adventures of Transformers Dark of the Moon.
