Me-Gyarido-Gi (メ・ギャリド・ギ Me Gyarido Gi?), also known as Unidentified Life Form #24 (未確認生命体第24号 Mikakunin Seimeitai Dai Nijūyongō?), assumes the form of a deranged punker who drives a truck he acquired from Giiga's killing its previous driver. When his turn came, Gyarido begins by committing mass vehicular homicide. With the Gouram's aid, Kuuga manages to catch up to Gyarido, who is forced out of the truck by Kuuga in Dragon Form before being forced to retreat through the sewers.

After acquiring a new truck and killing five men, Gyarido resumes his killing spree until Kuuga intercepted him in the Try Gouram, knocking the truck down while killing the Gurongi in the process.
