In the season one He-Man episode "Game Plan" the most powerful man in the universe is captured prompting Battle Cat and Ram Man to work together. When the pair invade Negator's base of operations they are confronted by the villain's Nerbs. As Ram Man sits still in recovery after smashing his way through an air vent Battle Cat takes it upon himself to let the Nerbs know that he means business. We are then treated to a very expressive piece of animation as you can see below, and one of the loudest Battle Cat roars in the series!
For your listening pleasure, ROAR!
