"I Will Not Be Stopped, Especially Not by Autobots!"

The Master Builders is a good episode from season two of Transformers that is a great Constructicon Episode and also showcases both Hoist and Grapple.

Grapple shows Optimus Prime a plan for a huge solar tower capable of capturing large amounts of power. Prime decides it is too risky to build because of what would happen if Megatron got his hands on it. The Constructicons confront Grapple and tell him that they want to help him build his tower and that they have left Megatron. But can they be trusted.

This episode is great. The Constructicons all get in solid action building things and they truly are "Master Builders". I always wondered though, were the Constructicons telling the truth to Grapple about leaving Megatron. Because it seemed they were and the only reason they did not do so was because Megatron over heard what they were saying and probably would have destroyed them. Also it is cool to see Optimus Prime playing basketball.

Devastator is awesome in this episode. I think this may be the best showing of Devastator and he gets in some great action at the end of this episode. Easily one of the best moments in Transformers history.

Constructicons and Devastator are both awesome and so is this episode.
