Sparkplug is the name of several fictional characters in the various Transformers universes.

Sparkplug Witwicky is the patriarch of the Witwicky family who was vastly unlike his two sons, in that he was portrayed in startlingly different ways across the two main fictions. The Transformers Classics Mirage toy sports an advertisement for Witwickey Sparkplugs, a reference to this character.

Although Sparkplug started out as being quite similar to his animated counterpart in the comic book universe, aiding in the repair of Bumblebee when his son, Buster, brought the injured robot to his garage, his personality took a sharp turn after he was kidnapped by the Decepticons. Instructed by Megatron to develop a process that would convert Earthen gasoline into fuel they could consume, Sparkplug drew on his memories of his time as a mechanic in the Korean War, recalling an instance where he had sabotaged the enemy vehicles' fuel and brake lines, and did the same to the Decepticons, poisoning their fuel and allowing the Autobots to snatch victory from the jaws of defeat. However, before this heroic act could come to light, many of the Autobots believed that Sparkplug had betrayed them, and an over-reactive Jazz let loose with his flamethrower, causing Sparkplug to have a heart attack. Thankfully, he soon recovered, but his opinion of the Transformers had changed with that action, and he forbade Buster from interacting with them again.

Ironically, Sparkplug would also come to fall prey to a hypnotic Decepticon device in the comic book continuity as well, drawn in by Ratbat's "Wash and Roll" car wash scheme, which mesmerised humans into giving up their gasoline to the Decepticons in a complex-yet-effective plan. Buster was able to break the hypnotic effect with a splash of water, and Ratbat's plan was foiled, but Sparkplug was given even more cause to hate the Transformers and their involvement in his life when the Predacons destroyed his garage and a vengeful Ratbat captured Buster. Even worse for Sparkplug, when his older son, Spike, returned from college, he took up with the Autobots and was binary-bonded to Fortress Maximus, becoming a mechanical freak in his father's eyes. Spike subsequently saved Buster from the Decepticons, and his father was overjoyed to have his two sons back, although Spike's bond with Fortress Maximus kept him returning to the Transformer war and eventually resulted in his death in battle against Megatron.
