TFA Drift/Deadlock

"He was once called Deadlock. A bot who felt no remorse. Just hatred. And anger. Many theorized he did his actions in the name of some ancient Cybertronian god... Leige, Liege... Something. As the war died down, Deadlock changed. He now wants to ally himself with the Autobots. The lone cyber samurai once called Deadlock became Drift. He wants to redeem himself for the actions he made... But still kick some tailpipe along the way." - Pharma
