Vexx is a video game developed by Acclaim for the PlayStation 2, Xbox and GameCube consoles released in 2003 while the Gameboy Advance version was cancelled. The game is a 3D platformer game, starring a character of the same name. The objective consists of collecting magical hearts and unlocking more worlds to play, defeating enemies and jumping across platforms. Vexx is armed only with the legendary Astani war talons, which give him the power to defeat his enemies, as well as fly and swim under water.

The introduction tells briefly of a planet called Astara that was inadvertently destroyed by its own inhabitants, who "opened a door better left closed". The planet was, in fact, destroyed by the Shadowraiths, who had poured through the Landspire and the Rift system that had been created by the ambitious Astani in order to access other worlds. The Wraiths, led by their leader Dark Yabu, attacked Astara, ultimately draining all of the energy out of the Rift system. However, an official supplementary comic reveals how Treyven, the Guardian of Astara, used the legendary Astani war talons to defeat the entire first wave of the Shadowraiths at the cost of his own life.

Seven hundred years later, Astara is literally in pieces, and all that is left are large chunks of land floating in an asteroid field. However, the individual pieces of the planet are still habitable. One village known as the Overwood, populated by a primitive race called the Valdar, is eventually discovered by Dark Yabu, who attacks the village with his Shadow Horde. The only Valdani who try to resist are Vargas, the village Guardian, and his grandson, Vexx. Despite their bravery, they are overcome by Yabu's forces and are shackled with the rest of villagers, all of whom are then made to toil in mines searching for Wraithearts - the last remains of the first wave of Wraiths and the only remaining source of the Rift system's power.

Vexx is "beaten with word and whip" until "his rage became unbearable", and he finally lashes out at his oppressors. He is stopped by Yabu, who would have killed him if Vargas had not then attacked Yabu to save his grandson. Furious, Yabu turns on Vargas instead and murders him with his shadow powers. Later that night, determined more than ever to get revenge, Vexx sneaks out of the caves and onto Yabu's windship. There he discovers Treyven's skeleton wearing the legendary Astani war talons and clutching a spire of rock. Yabu had kept the talons hidden for years because he was unable to destroy them and feared them falling into enemy possession. The talons permanently attach themselves to Vexx's hands, at the same time causing an explosion that destroys the windship and nearly kills Vexx. While he is unconscious, Vexx learns through a vision that Vargas' soul is still imprisoned within Yabu's magical amulet; Yabu plans to feed on the soul's pain and misery until Vargas is no more. Vexx is then taught how to use the Astani war talons while still unconscious by the weapons themselves, which pass on all the knowledge and experience of the previous talonbearers.

Dark Yabu has not been a contender in any CBUB matches.
