Growler

Growler is a burly dog starring in the action series (and movie) "Babies VS Dogs", a show within the Teen Titans Go! show. He first appeared in "Classic Titans" as an action hero and reprised his role in the "Teen Titans Go! Hollywood Special" episode.

History
It's never been revealed what Growler (if that's even his real name) does outside his professional life, but in Teen Titans Go!, he stars as a viciously ripped action-villain dog in the show "Babies VS Dogs" and the spinoff movie.

During the film in "Kabooms", Growler is seen on screen riding a motorbike across the barren highway to meet his opponent, a little baby named Jack. The two meet at the toddler's cabin and duke it out in an intense duel. However, when tres Cyberhackers show up to attack the U.S. President's house, Growler and Baby Jack have no choice but to fight together. Unfortunately, Jack's cabin is blown up, and both he and Growler are knocked unconscious.

Later in the flick, Growler finds himself with Baby Jack tied to a chair in an empty room. Now that they have a chance to become friends and open up, Growler begins to recall stories of his dad training him to be a fighter and living on the farm. Once Baby Jack start chiming in with his nonsense, the Teen Titans, who have been watching the movie, teleport inside of it to free them and stop their uninteresting exposition. The Cyberhackers reappear and beat up Growler and all of them, but fortunately they are defeated when the Titans manage to bore them to death with character-building. Growler and Baby Jack rejoice that the villains have been defeated.

Characteristics
A strong contrast to his baby counterpart, Growler is a big, burly, yellow bulldog. His muscles and various tattoos (including a dog skull and bone on his right arm, a fire hydrant on his left, and a stabbed heart on his chest) combine to make him look incredibly buff and tough, not ready to put up with any stupid stuff... He wears a spiked bracelet on each wrist and covers up with a ripped-up pair of purple shorts. To finish up his gnarly demeanor, Growler combs his hair into a green mohawk.
