Captain Big Nasty
From Multiversal Omnipedia
Captain Big Nasty was a robotic intergalactic police officer and the captain of the Outer Space Patrol. The alien criminal Wacko was in his custody until Wacko escaped and stole several seismospheres. Big Nasty followed Wacko to Earth where he was initially regarded as a villain by Darkwing Duck and Gosalyn, due to him threatening the supposedly cute and innocent Wacko. Eventually though, he revealed himself as a law enforcement officer and teamed up with Darkwing to catch Wacko before he used the seismospheres to destroy the universe.
