The name Hook has been applied to several Transformers characters.

• 1985 — Hook the Constructicon crane from Generation One.

• 1990 — Hook the herald of Unicron and companion of Line and Sinker from the Marvel comic book.

• 1998 — Subsector Hooks the area on Earth in the Beast Wars cartoon.

Hook should not be confused with...

• Hightower, the default name for crane-formers after Hasbro lost its trademark on "Hook."

• Gren the Decepticon Micromaster crane from Generation One, whose name comes from the Japanese name of the Constructicon Hook.

• Wideload the Decepticon Construction Team crane from Energon, whose Japanese name is also "Gren."
