Transformers Animated Season 1 Episode 12 - Survival of the Fittest Episode Title:Survival of the Fittest.Episode Description:Sari is abducted by the Dinobots. Prowl and Bulkhead go to Dinobot Island to investigate, followed by Capt. Fanzone. The trio are attacked by the Dinobots, and discover they all have acid burns on their bodies. Worse, it is the work of Prometheus Black (AKA the acid-shooting Meltdown) who has forced the Dinobots to become his watchdogs, and wants to use Sari as part of his experiments to create a transforming human. His previous experiments having failed, Meltdown thinks that a still-growing human, as opposed to an adult, will have better results, and chooses Sari because he hates Sumdac. Bulkhead is heavily injured by Meltdown, and only Sari's key can save his life. Prowl and Fanzone team up to free Sari, but they have to first fight Meltdown's mutant freaks. They take out Meltdown by wrapping him in a non-corrosive containment suit and, after the Dinobots take out Meltdown's mutants, return to the city, leaving the Dinobots on their island.
