Marcus Castor

Marcus Castor is a human from the live-action film continuity family.

Marcus Castor may look like a surfer dude, but he's also a charismatic rabble rouser. It's unfortunate for the Autobots that he's chosen them as the subject of his anti-Cybertronian crusade, especially as he is gaining quite a following. Also, buy his T-shirts!

Castor chose the Tech Museum of Innovation in San Jose as the location for his protest and achieved quite a crowd. As he delivered a speech about how the giant robots from space were disrupting the humans' lives, Ratchet attempted to reassure him that the Autobots were solely here to help. Castor remained unconvinced and argued at length, until Ironhide attempted to "help" as well. The increasingly-heated discussion was interrupted by a missile that struck the museum, signalling the arrival of Starscream and Barricade.

After Ratchet was wounded, Castor was surprised by the sight of Ironhide charging at the enemy to protect the humans. Ratchet tried to protect the humans as Starscream hurled a tanker truck at them, but they were ultimately saved by Ironhide tackling the tanker out of the way. With Ironhide down, the two Decepticons moved in, but Castor, wielding a blow torch, led the human protesters in a spirited attack on the pair. With the addition of Optimus to the fight, the Decepticons fled and Castor, now firmly an Autobot supporter, unveiled his design for an anti-Decepticon T-shirt. Automatic for the People
