Griffin was also a character in the 2008 movie Jumper. Griffin did not appear in the novel that the movie was based on, and was created just for the film. Steven Gould, who wrote Jumper, worked with the film makers to write Jumper: Griffin's Story as a prequel to the novel. There is also video game based on the character. The movie's protagonist was David Rice, who had the ability to teleport anywhere in the world. He, and others like him were considered dangerous and were hunted down by Paladins who wanted to kill all who had the ability. David discovered another jumper named Griffin, who wanted to kill the paladins as much as they wanted to kill him. Griffin tried to kill the paladins with a bomb in the apartment of Millie, David's girlfriend. David trapped Griffin in power lines in a war zone in Chechnya, and that was the last we saw of him.
In Men in Black 3, Griffin was an alien who had the ability to see all possible futures. He also possessed the ArcNet, a shield which was the key to saving the Earth. He helped Agents K and J set the timeline right after Boris the Animal went back in time and changed it.
Griffin can also be a subtle nod to Gryffindor, one of the Houses of Hogwarts, named after Godric Gryffindor.
The classical griffin was a legendary creature with the body of a lion and the head and wings of an eagle.
