Hook is a Decepticon from the Transformers: The Movie franchise.
Hook is the largest Constructicon. He is the "Wrecking Ball" of the constructicons and is always being bossed around by the other Decepticons, but he always looks on the bright side of his job, smashing things!. Besides, he probably isn't smart enough to think of the down-side of his job. He has a very limited verbal range, and he can barley pronounce his name right. Cliffjumper is killed under his flail, but he is not the only Autobot smashed under his huge weapon.
To be added...
Hook 's main offense is his "Crane Flail", which he can use to deadly effect, but he also has a pair of shoulder mounted rocket launchers.
