Sideswipe

Original background story
Sideswipe is the second oldest Junkbot. He spends half his time trying to be as bad as his big brother, Piston Head, and the other half tattling on him! The Junkbots make fun of Sideswipe, but the Crash Dummies know he's no joke! He can smash a Crash Dummy to spare parts faster than a head-on collision!

"You think running into a brick wall is dangerous?" asks Sideswipe. "Try running into me!"

History
Sideswipe was released in 1992 with the other Junkbots. His figure lacked any Crash Dummies triggers and proved to be fairly unpopular. His head and arms were still removable. He came with a special cannon that could hypothetically trigger a Dummy's button if it hit it right.
