Bull rancor

"...And if you're thinking of escaping, just remember, my new pet is very hungry"

- Maris Brood reminding Bail Organa of her pet rancor

The bull rancor was a much larger subspecies of the common rancor. They were often found on the jungle world of Felucia. When prey was scarce, they had to revert to eating the giant fungi growing on their home planet; this was one possible explanation for their size and color.

Characteristics
The bull rancor was a male that was marked by its paler flesh, elongated tail and immense horns that sprouted from its massive head. These generally solitary creatures were incredibly dangerous, even to other rancors, and guarded the legendary "rancor graveyard" on Felucia. They were noted to have been much more aggressive than their female brethren and the Felucians believed that they were incapable of being captured or tamed.

Bull rancors were much more massive than a normal rancor and possessed a gray skin color. They had long arms and large hands like those on a female rancor. The species also had four long curving tusks that protruded from their spiky heads, as well as much longer tails than those on a female rancor; due to the much larger size they often dragged on the ground. They were exceedingly rare. The Bull rancor also has a spiny back and tail. It has short legs similar to females .It also is surprisingly fast although it has so many armour plates. Its nose is on top of its enormous head. It also has one row of teeth and can have many sets of teeth.

History
After the death of her master, Padawan Maris Brood began to slip to the dark side of the Force whereupon she formed a strong bond with a bull rancor on Felucia. The creature became her new "pet" and was intensely loyal to Maris, willing to fight to the death to protect her. When she captured Senator Bail Prestor Organa, she warned him not to escape as the bull rancor was "very hungry." When Galen Marek came to the planet again to free the senator, Maris sent forth the bull rancor to stop him. However, the creature was wounded by Galen Marek.

Behind the scenes
There is a discrepancy between the bull rancors that appear in Star Wars Galaxies and the ones that appear in The Force Unleashed, with the Galaxies ones more closely resembling normal rancors, as does the Bull rancor depicted in the Star Wars Galaxies Trading Card Game. This may be because Maris Brood's Bull Rancor was possibly warped by the dark side of the Force, along with Brood. Brood's Bull Rancor is black (or very dark green) and covered in large horns and tusks.
