Megatron has the Golden Disk.
The Golden Disk from the Voyager probe is a recurring object throughout the Beast Wars. It plays a major role in the escalation of the conflict between the Maximals and the Predacons and leads to the death of Dinobot. It is eventually destroyed, but the Predacon leader, Megatron, recovers one of the shards and shows a Cybertronian government agent a piece of a message that was enscripted into it from his former boss.
