Spike was an adolescent woking with his father Sparkplug on an oil rig, when the Decepticons attacked. After the Autobots rescued them, they volunteered to become their native guides to planet Earth.

Spike had many adventures with the Autobots. In the course of these adventures he met Carly an impetuous prodigy and MIT graduate. Despite being smarter than him, older than thim (she could drive) and hotter than him, Carly displayed a noticable affection for the somewhat-dim Spike. They mated and produced offspring.

Spike later become an ambassador or something. He polished up good.

Marvel Comics continuity
Spike Witwicky was not introduced in the Marvel Comics series until issue #38, where he first appeared looking for his lost brother, Buster, who had been captured by the Decepticons. Spike soon became the binary-bond partner to the Headmaster Fortress Maximus, after Fortress Maximus' first partner, Galen, was killed in a battle with the Deception Scorponok.

In an alternate timeline in the year 2009, Spike Witwicky was part of a very small Autobot/human resistance movement in a world where Galvatron II's Decepticons controlled North America. The handful of Autobots who remained alive despaired and were on the cusp of giving up, but Spike and Lisa (who shared growing feelings for each other) guilted them into one last suicidal attack on Decepticon headquarters in New York before the rest of the world could unleash a nuclear holocaust onto America at midnight. Though there were several casualties, Spike managed to hoist an American flag on the Decepticon stronghold on live television, a symbollic measure which prompted the end of the planned nuclear strike. Before Galvatron II could respond, the Decepticon despot was abducted by Hook, Line, and Sinker into another timeline.
