Ep 25. The Incoming Asteroid Emergency

Bex escapes in a massive airship, triggering a laser that sends an asteroid hurtling toward Dino Earth. The Metatron and Mosa-Storm try to divert it but fail, combining to smash the asteroid instead. They blast most meteors but one heads for the ocean. Trina sacrifices herself by flying the Mosa-Storm into it, leaving Dinoster racing to save her from the wreckage.
