Rico

Rico is a G.U.N. trooper and member of Paladin Team Sigma-Alpha 2. He and the rest of the team were responsible for the capture of Sonic the Hedgehog who had been framed for the theft of a Chaos Emerald that had actually been stolen by Shadow the Hedgehog, although Sonic escaped their custody while flying in a helicopter. He would later meet Sonic again as an ally during their mission to defeat the evil Dragon, Zan.

Search for Sonic the Hedgehog
Rico was part of one of the first missions given to Paladin Team Sigma-Alpha 2; the capture of Sonic the Hedgehog, when they believed he was responsible for stealing the city's Chaos Emerald. (StH: #98)

The Dragon Conflict
Some time later, Rico and Paladin Team Sigma-Alpha 2 were once again deployed, this time to work with Sonic and the Knothole Freedom Fighters in bringing an end to the terror brought on by the dragon Zan. Spike told Rico he heard a noise, but before he could respond, both he and Spike was captured by Zan. They later rejoined their team after Zan was killed. (StH: #107)

Later Missions
During the Xorda's attack on the planet, Rico and Sigma-Alpha 2 were among the G.U.N. soldiers on the field of battle against the Quantum Dial. (StH: #125)
