Terror Guma

The Terror Guma (テログマ Tero Guma) or Terror Bear, also known as the Long-armed Bear (手長グマ), is a creature developed by Dr. Indigo using the chemical SIQ for Shiki's plot to use monstrous creatures to attack East Blue to force the World Government to submit to him. It is a black bear with white stripes on its body and long arms.

The most notable feature of the Terror Guma is it's all crushing strong arms. Using these very long arms its strikes are very likely to result in a killing blow. It's cute round eyes are quite deceiving of this creature's violent nature.

The Terror Guma first appeared in One Piece Film: Strong World. It defeated Don Kamakiriri before turning on, and ultimately being defeated, by Luffy.
