Beast Wars: Transformers S01E01 - Beast Wars (Part 1)

After travelling into the distant past via a transwarp drive, the Maximals battle the Predacons in outer space, but both ships crash land on a mysterious planet. They scan for beast forms to protect their robot forms from the planet's large amount of Energon. Enraged by the apparent failure to land on Earth, Dinobot challenges Megatron for leadership of the Predacons, but is blown away by Scorponok. After the first battle on the planet between the Maximals and Predacons, Dinobot reappears to challenge Optimus Primal for leadership of the Maximals.
