In this timeline, Fleetway's form had been "sealed" away when Sonic was younger (he basically learned to better control his chaos energy without awakening Fleetway), but because of an imbalance of his chaos energy, Fleetway is back, and he is taking a whole LOT of interest in Shadow

Also, a few notes:

- Super Sonic exists without “Fleetway”

- Shadow became Super to stop "Fleetway" when he first appeared again

- “Fleetway” keeps managing to take control of Sonic’s body more frequently. But at least he seems more interested in bugging Shadow than causing destruction (for now)
