Slugslinger is a minor antagonist in the Transformers franchise, especially Generation One.
In the three-part miniseries "The Rebirth", Slugslinger is among the Decepticons who pursue a group of Autobots to Nebulos in search of the Key to the Plasma Energy Chamber. After they were beaten back by the new Autobot Headmasters, Cyclonus did a deal with the Hive, which led to Slugslinger being upgraded to a Targetmaster and partnered with Caliburst. After retrieving the key, they returned to a furious Galvatron.
In the Headmasters miniseries, it is Scorponok that Slugslinger follows to Nebulos in pursuit of their Autobot rivals. The Decepticons mirror the Autobots' creation of Headmaster and Targetmasters. In the UK annual story "The Final Conflict", Slugslinger helped the Decepticons plot a course for Earth by stealing a fuel converter from the Autobots while they were distracted by a duel between Scorponok and Fortress Maximus.
After reaching Earth, Slugslinger was among the Decepticons who retrieved Scorponok's head when it was stolen by Highbrow and were temporarily trapped in limbo when Soundwave and the Terrorcons travelled back from the future. He fought the Autobots in the Arctic during the Underbase Saga and was last seen among a delegations of Decepticons objecting to Scorponok allowing the treacherous Starscream to join them.
