David Cross provided the voice and appearance of Zyro.
His business is in trouble and losing money, and this is due to his rival and arch-enemy Berkley, who owns a similar company. Zyro and Berkley's rivalry began at a science fair, where Zyro beat him, which led to Berkley swearing revenge on Zyro.
Events of GTA: San Andreas
War against Berkley
Zyro later phones Carl, to see if he can help with his business. Carl buys the shop, and then begins to help Zyro.
Carl shooting down remote control aeroplanes, destroying delivery vans and killing delivery boys, and finally defeating Berkley in a miniature war game. Winning the war game finally forces Berkley to leave San Fierro, allowing both Zyro and Carl to make money from the shop.
Zyro then lends his expertise to Carl Johnson and Wu Zi Mu as they plan to pull of a heist at Caligula's Palace in Las Venturas. This includes creating devices to stop the power from Sherman Dam, stealing four HPV-1000 police motorcycles and stealing a Leviathan.
Zyro also participates in the heist itself, instructing Carl Johnson, Wu Zi Mu and three others around Caligula's Palace. However, prior to the heist he told Berkley, putting the whole heist at risk. Carl punches him in the face at the Verdant Meadows airstrip, making Zyro fall to the ground. What happened to Zyro after these events is unknown, though it is most likely that he is still working for Carl.
Zyro also makes an appearance on the second set of Lonely Hearts, saying he doesn't want to be a virgin all his life. The host Christy MacIntyre says she cannot help him and wouldn't even suggest him to a hooker.

- In the mission "Wear Flowers In Your Hair" Zyro will drop remote control charges if killed, so one can assume he's wielding the controller, though the idea is to make the player think that he/she is controlling the RC Goblin.
- In the mission Breaking the Bank at Caligula's, in the ending cutscene after CJ punches him, it looks like Zyro is dead - however, this doesn't happen, since his missions can still be performed after this one and his appearance on Lonely Hearts is still heard.
