S02E49: B.O.T.

During a battle, the Protectobots finish off the Combaticons, with the exception of Swindle. Megatron orders Swindle to reconstruct his destroyed comrades or else a bomb in his head will go off, destroying him. As Swindle works to complete this task in time, three students get a hold of Brawl's personality component and use it for their science project, B.O.T., with disastrous results.
