Chupacabra is a small, insect-like karate master. He has four limbs with two compound eyes dark skin, and a narrow mouth with a drill-like proboscis. He wears a white gi which has the word Vampire (吸血?) in Japanese written on the left breast and is secured by a black belt.
More than a hundred space karatekas attempted to join the Space Karate Forces as reserve members before the Block-B semifinals of the Tenth Zenith of Things Tournament in ES 591. During the free for all that Zekka had them undertake as a means of trying out, Chupacabra attacked an opponent by puncturing the back of his head with his tongue while hanging on to him from behind.
