Transport to Oblivion | Transformers: Generation 1 | Season 1 | E04 | Hasbro Pulse

The Decepticons, working with Shockwave on Cybertron, create the "space bridge"—a device to transport energon cubes between the two planets. When Spike and Bumblebee stumble across the riverbed where the space bridge is being tested, they are captured by the Decepticons, who intend to use the boy to guide the energon shipment through the dangerous device. Bumblebee escapes, and ultimately leads the Autobots back to rescue Spike and destroy the shipment.
