Ricardo was a male human who lived in an alternate version of Earth created by the Trickster. In his world, Chrissie Jackson had dumped her former boyfriend Ivan after Andrea Yates saw him snogging Lorraine Groom. Chrissie later met Ricardo and dated him. Since Ricardo didn't have as much money as Ivan, Chrissie needed a bit of extra cash, so started to work at a supermarket. Maria Jackson had already met Ricardo plenty of times.

Ricardo went to Andrea Yates' party at the day the meteorite K67 was going to hit Earth. Chrissie and Alan arrived at the party when Ricardo was already there. After talking to Andrea for a while Chrissie went to Ricardo and greeted him with a kiss. (TV: Whatever Happened to Sarah Jane?)
