Roles in House of the Dead EX
Zobio, a simple zombie prison guard, falls in love with Zobiko, who was thrown into prison by a mad doctor, and breaks her out of prison and tries to take her to safety. Along the way, they must escape the zombie horde and survive by doing various over-the-top missions, like street racing, collecting apples, provide lighting for a zombie concert, and even take pictures of zombies to stop them dead in their tracks and force them to smile in order to run away and start a new life.
Both Zobio and Zobiko make an appearance in the game as unlockable characters representing the House of the Dead franchise. Their vehicle is the "Hotrod of Horror" and their All-Star move involves Zobio taking a potion that increases him in size as he hops out the vehicle with Zobiko riding on his shoulders; he takes out other racers by pounding them into the ground. According to the announcer's speeches, Zobiko does most (if not all) of the driving. Zobiko is absent from the DS version.
Sonic & All-Stars Racing Transformed
Although not playable, Zobio and Zobiko make a cameo appearance in the game, in the track "Graveyard Gig" in the Classic Cup. In the first lap, Zobio can be seen bouncing on a bouncy castle. In the last lap, Zobio and Zobiko dressed in wedding clothes can be seen on the screens in a concert, and can be seen both in a ruined church to the right near of the capsules.
