What is this creature?

I would give you a picture, but all I can give you is a description. It is the huge gorilla-like thing with tusks that throws a rancor at Galen Marek, or Darth Vader's secret apprentice, when he steps into the arena. It is from the world premiere video of Force Unleashed II. I am a big Star Wars fan and I am quite confused at what it is for no creature in Star Wars matches its size.
