Barricade

"Hey kids, wanna ride with the siren on?"

- Barricade to the children he kidnaps

Barricade or Barry was a male Decepticon police robot. He later joined the Shadow Minds.

Cybertron Life
Barricade began life as the chief of Cybertrons police force, in charge of keeping law and order. They often captured criminals and inprisoned them but then the Decepticons rose, a more organised group then any of the useless crime teams on Cybertron. I mean, one of the groups used banana guns. The decepticons sent Lugnut to attack a large conviniet bank in the capital. The police shot him down, and barricade spoke to the con before he died.

Barricade then decided to join the decepticons and blew to his own station, killing all the police officers in the building. He then met with the decepticon leader, Darth Megatron and became a commander as the decepticons grew. He left Cybertron with his master and some other decepticons to go to earth.
