Here is what Judge Dredd: The board game has to say about him:
Judge Dredd's 'brother', his clone, and also a Judge, Rico was the faster and more accurate of the two but was flawed, taking bribes and running a protection racket. Judge Dredd brought him to justice. The punishment for bent judges is severe - 20 years on the penal colony on Titan where the perp's nose and mouth are sealed and the body adapted for work on the airless planet. Rico returned to avenge himself, but 20 years had slowed his draw, and he was killed by a regretful Judge Dredd.
His Perp card in this game is worth 8/10. The illustration for the card is taken from Prog 30, page 10, panel 4, although the speech bubble is lifted from the panel beneath.
