Sonic and Tails look for their third emerald thats located in a place called Floating Island. After their arrival, a mysterious looking fist with brass knuckles pops out of the bushes along with a shadowy figure saying "that blue haired kid ain't gonna get my emerald". Later, as sonic and tails search in the jungle, a super robot named frankly confronts them and fought. Sonic wins the fight while frankly was about to use his ultimate attack until the shadowy figure appeared out of the bushes and is revealed to be knuckles, a teenage boy with red dreadlocks and brass knuckles. Knuckles defeats frankly for now as he retreats back to robotnik. Sonic thanks knuckles for beating the super robot but knuckles angrily tells the two that they better not steal the master emerald or else they'll get a beating of a lifetime.
