A creature composed of various animal parts, Gigaro commanded the Synthoid-Beast Army. Gigaro was originally a skeletal creature on a desert planet in the Garo dimension, hunted for unknown reasons by humanoids. Exhausted and near death, Gaohm gave him a new powerful body and recruited him into the Jamahl. Gigaro used a white bonelike sword and his whale-flatop could open to reveal a gun. Gigaro imbued himself with life energy meant for the Jamahl to power-up into Final Gigaro, a red and white version of himself with more power. He was ultimately killed by his master Gaohm so that his life energy would accelerate the completion of the Jamahl Hole in Episode 47. Gigaro was originally supposed to be revived and absorbed by Jagul, but Mai and Kabuto's interference it didn't come to be and left Jagul with a weakpoint on her new body.
