Who Is The Robot In The New Animated Transformers?

he is in the episode where the autobots get turned to humans by soundwave, and sari finds him in the lake, so he becomes one of the substitute autobots…he is kinda crazy, if you tell him he;s a hero he says he’s a hero, if you say he;s a decepticon, he thinks he’s a decepticon…but i dont rememeber his name and its buggin me…
