He is usually seen as the true villain of the animated Disney film, Treasure Planet, seeing as he is more ruthless and possesses a crueler nature than Silver.
Disney Vs Non Disney Villains
Thrax takes down several crewmen from Long John Silver's crew, though the captain does not want to participate in the war. Scroop disapproves of this and challenges Thrax to a fight. After slashing a rope that Scroop is hanging on to, Thrax watches his rival fly off into the atmosphere.
Disney Villains War
As in the Disney Vs Non Disney Villains War, Scroop resists the hiring of Silver's hiring crew; instead, the employer is Emperor Zurg. Scroop rushes the emperor, but he reverses the gravity of the ship. Scroop barely manages to hang onto a flag to prevent himself from flying off into space, but Zurg cuts the rope to the flag. Scroop wails as he flies off into the cosmos.
