During the Ixis Resurgence taking place in New Mobotropolis, half of the Secret Freedom Fighters–Silver the Hedgehog, Shard the Metal Sonic, and Larry Lynx–went there to find Naugus' apprentice, Geoffrey St. John and to stop the skunk. However, they found his Extreme Gear laying on the ground. Shard planted a tracker on the board and the heroes went on. Inside the Ixis Ruins of the area, Geoffrey was off to collect the bones of Ixis Vale for Naugus to use for his plan for a new Order of Ixis. However, the three Secret Freedom Fighters caught up with Geoffrey, only for him to escape and trap the heroes inside the cave alive. Shard was able to drill his way out, only to lose Geoffrey. They quickly escaped, as they had failed their objective. (SU #41, #43)
