As Gills, Ashihara becomes a truly formidable warrior, with a ferocity that allowed him to rival even Agito. In one-on-one combat, he and Agito's fighting prowess would be considered equal. However, the transformation was unstable and carried detrimental effects to Ashihara’s body. The transformation was so unstable that Ashihara’s body began to degrade from accelerated cellular decay. The cellular damage on his body became so severe that he had died from the effects only to be revived thanks that the intervention of others. He was revived once by the OverLord, then again by Mana Kazaya. However, after being resurrected by Mana Kazaya's supernatural healing power, Ashihara discovered that his body chemistry was also altered; able to now accommodate the transformation.

The Wiseman’s Orb is fitted onto Gills' forehead and he is able to open his faceplate, exposing the Demon Fang Crusher jaws. To aid him in battle, Gills has an assortment of natural weapons. He is equipped with the Gills Claw blades on his forearms and the Gills Heel Claw blades on his heels. He is also able to extend tentacles called the Gills Fillers from his wrists. Gills is extremely resilient, having survived several near-death injuries, including a barrage of specialized bullets designed to subdue Agito,

Gills' initial form, later taken again when defeated by the El of the Ground, featured notably shorter horns. They grew due to rage during his first battle with Anguis Masculus into their full normal size.

Finishing Attacks

  • Gills Heel Claw: With the Gills Heel Claw extended, Gills leaps into the air with a devastating overhead heel drop, with enough power to pierce even the sturdiest of Unknown bodies; from that point, he tears away with a flip kick finisher.
  • Gills Hell Stab: Gills points out his middle and index finger and stabs the enemy piercing right into the foe's body. This attack was only seen in the Kamen Rider Agito Hyper Battle Video Three Great Riders.
