Marvel Generation One comic
Seattle's Fort Lewis was the site chosen for the activation of Power Station Alpha, which was overseen by congresspeople, guarded by G.I. Joe, protested by anti-nuclear-power demonstrators, menaced by Dreadnoks, infiltrated by Bombshell, and ultimately stolen by Cobra. And in the middle of all that, it was also the site of Bumblebee's fateful destruction. However, the hapless Autobot's life was saved by the happy coincidence that G.B. Blackrock was enjoying a pleasure cruise in the area. When the industrialist's boat was the random victim of Cobra fighter-jet fire, the Joes who rescued him happened to bring the Transformers up in conversation, and he quickly volunteered his help. At Fort Lewis, he convinced them that Bumblebee was an ally worth rebuilding, which they did - into Goldbug.
