Barricade is a Decepticon from the Energon portion of the Unicron Trilogy.
Cartoon[]
He made a super rare robot appearance in an Energon episode along with Steamhammer. He was going to appear with Heatwave in a deleted episode called "CyberWarped!" but the episode had another guys idea in a Tarnsformers Animated episode called "This Is Why I Hate Machines!" & nobody would like Cybertron on Us but mostly, people LOVE crossovers.
Toys[]
See Bruticus Maximus.
He was repainted into Onslaught & Heatwave.
