Knuckles and the Chaotix Crew arrive on Flickies' Island on a search mission, with the dual aims of ensuring there are no signs of Robotnik and finding something they can use against him in the war. The group come across a cache of Knuckles Metallix but inadvertently trigger the Metallix' security protocols, leading to a fight breaking out. Knuckles notes that the Metallix are probably not properly charged as they seem much weaker than usual, with even Charmy being able to defeat one of the machines.
