Wings Universe
Kup and Thunderclash once went to Derelictus Five, where they were attacked by the natives. Despite their overwhelming odds, the two Autobots were able to subdue the Derelictuskans by shooting loose a power line, which in turn shocked the Derelictuskans.
During a later battle with Devastator, the two tried the same strategy, but the power line failed to take down the giant combiner. However, it gave Dion the idea to give the Decepticon a bigger "jolt" by having all of the Autobots present shoot at Devastator's knees. This tactic finally brought down the giant.
