Ikahula

The Ikahula 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 giant squid-like creature. Its body is mostly yellow colored, and his head has some red stripes. It uses dozens of tentacles to attack its enemies.

It appears in One Piece Film: Strong World, when the creatures from the flying islands invade Merveille. A Ikahula is seen attacking allies of the Golden Lion Pirates.
