Transformers: Armada

Threaten (1x38)

:

Starscream brings Megatron the Skyboom Shield and Star Saber, completing the 3 Mini-Con powers (with the Requiem Blaster). Thrust proposes the Hydra Cannon (as Sideways put it). Fred convinces the other kids to skip school to see an approaching comet that has the human population abuzz. Prime hasn't lost hope in Starscream since he is a Transformer and can still do the right thing. The Decepticons leave the moon in their completed spaceship and test the Hydra cannon on the comet, blowing it up. Megatron then tells Starscream to target the Earth!
