Growler is a character from He-Man and the Masters of the Universe.
Growler is a mechanical dog built by Baron Grod. His extendable nose allows him to track scents, and his radar tail and ability to fire stun beams from his eyes make him a valuable asset in his master's hunts.
With Growler's help, Baron Grod captured the last of Eternia's unicorns. When He-Man and Battle Cat launched an assault on the baron's fortress to release the unicorn, he ordered Growler to attack them, but Battle Cat jumped to He-Man's defense and smashed Growler to pieces.
