Zan was a large red scaled Dragon native to the planet Mobius. The abusive mate to Dulcy during her time spent near the United Federation territory, Zan was a racist to all other species because he found them inferior to dragons. When Station Square sent military officials to scope out the island where he and Dulcy were living, Zan was infuriated, attacking Station Square in retaliation. Sonic the Hedgehog was then sent to help G.U.N. defeat Zan in order for Station Square to take in some Overlander refugees from Robotropolis. Once the strike force landed Zan started to pick them off one at a time. Sonic, Tails, and Bunnie were soon reunited with Dulcy in Zan's cave. When Zan found the three "lesser beings" he was going to fry them, but was calmed down by his mate. Sonic and company soon fought against him for Dulcy's sake (due to the fact that they saw him abuse Dulcy). In the end it wasn't Sonic who slayed the dragon - the remaining G.U.N. troops blew the cave up ensuring Zan's death. (StH: #106, #107)
- Zan's appearance is based off of Chinese depictions of a dragon.
