Fiction

Marvel UK Generation 1 comics

A Decepticon team led by Soundwave used the sonic lance to control Sludge, who had lost higher functions due to his cybo-dendron burning out. The Dinobot was set loose on Doonstown and the sonic lance was stored in the cloaked Ark shuttlecraft that the Decepticons stole from a trio of Autobots. In case it was discovered, the sonic lance was booby-trapped by Scavenger to explode if it was turned off.

And discovered it was, by Bumblebee, who used a portable energy trace to find the cloaked ship. He discovered the sonic lance and, knowing that the Decepticons would leave a nasty surprise, evacuated the Autobot hostages kept on the ship and shot the sonic lance, causing an explosion that engulfed the sonic lance and the ship.
