Fallout (G1)

Fallout is a hired assassin.

Fiction

IDW comics continuity

Fallout and a bot named Streaker were hired by Proteus to execute two pro-Decepticon activists Momus and Sherma. They were sent to a Relinquishment Clinic to aquire new bodies with jet alt-modes to do the job. They succeeded in killing Sherma and easily dispatched Momus in Translucentia Heights. However, Chromedome saw Fallout fleeing the premises. During a chase, Fallout was killed when he flew through transparent glass in a tunnel and came out the other end to smash into an ironic billboard. Shadowplay, Part 2: Patternism

Notes

Fallout and Streaker play a similar role to Sonic and Boom for being hired to another's dirty work.
