Spike

Spike 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
Spike was part of one of the first missions given to Paladin Team Sigma-Alpha 2; capture Sonic the Hedgehog, when they believed he was responsible for stealing the city's Chaos Emerald. In reality, the emerald was stolen by Sonic's look-alike Shadow the Hedgehog. Although Sonic was captured by the team despite putting up resistance, he managed to escape from their helicopter while being transported to prison. Eventually Shadow's identity became known, and Sonic was exonerated for the crime. (StH: #98)

The Dragon Conflict
Almost a year later, Spike 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. Sigma Alpha 2 planted the explosives in the dragon's cave that resulted in his death. In exchange for the Freedom Fighter's help and information on Dr. Eggman, Station Square accepted the numerous Overlander refugees that the Freedom Fighters had rescued from Robotropolis.
