scene is from season 1, episode 2

you were one of the Decepticons and you were a witness to what will happen if dark energon reanimates Cliffjumper. You watched closely as Megatron inserted it and the body of Cliffjumper came to life only to be snarling and making these zombie noises. Out of control, the body lunges at Megatron only to be shot by him and the body fell to the plummeting depths where it landed lifeless again.
