Subtitle: High Speed Monster (高速怪獣 Kōsoku kaijū)
Originally one of the three monsters used by the Zenekindarl people to conquer the prehistoric Earth, Dexador was sealed into a ground painting after his purpose was fulfilled, but was also forgotten by time when the Zenekindarl people went extinct, going into complete hibernation along with his comrades.
Later, when an accident caused three Zenekindarl people to become reborn in the present, Dexador was reawakened to cause damage in the skies, being the Zenekindarl peoples' most trusted. Soon, TPC took notice and sent the Passion Red squad after the kaiju, whose existence was not yet known due to his speed. The wing creature easily surpassed the already accelerated Passion Red and destroyed the small squadron of two, but gave away his identity. Later, Dexador and his comerades were to be summoned to cause damage, but was destroyed in mid-transformation by the Super GUTS. However, the Zenekindarl people refused to give up as they focused their will power from three separate entities to one, recreating Dexador and sending it to the skies. The Super GUTS then separated to have its fastest ship: GUTS Eagle Alpha, go after the creature, heading towards cities. However, Alpha's speed still cannot match the creatures and Ultraman Dyna was called into action. After quick wrestling, Dyna was trapped in the creature's Mind Control and was paralyzed, only to be saved by Ryo and Kariya, who killed the Zenekindarl people. Dyna then changed into Miracle Type and reflected the Mind Control back to Dexador. Dexador then tried to flee, but was shot in midair by Dyna's Solgent Ray and destroyed.
