Scroop

Scroop is the primary antagonist of the disney 2002 animated film Treasure Planet. He is a crab-like spider-like extraterrestrial who was a member of John Silver's crew. Like Silver, he wanted the treasure as well.

Story
Scroop was prepared to kill Jim Hawkins when he was eavesdropping. That is, until Silver intervened. His most memorable act, however, was when he killed Mr. Arrow, the Captain's mate. When they were nearing a blackhole, Scroop cuts off Arrow's lifeline, and allows him to fall into the blackhole. He then frames Jim for the murder. When he was fighting with Jim on the ship, B.E.N. the robot accidentally switches off the gravitation wire, thus making the gravity disappear. As Jim was holding onto the flagpole, Scroop attempted to cut off the rope, just as he did with Arrow. However, Jim outsmarts him, and ties him up with the flag. The rope snaps, and the murderous alien drifts off into space, floating upwards to his death.
