Cobra was a master of Serpent Karate.
Cobra was one of more than a hundred space karatekas who 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. He fell into a group of what martial arts scholar Hegeor Hopper termed unidentified martial artists. During the free for all that Zekka had the karatekas undertake as a means of trying out, Cobra challenged another unidentified martial artist, Kraken. He did not survive the carnage and was later shown among the numerous karatekas who had fallen.
