PlotEdit

Sonic and Tails try to prevent Robotnik from altering history, encountering the Organisers–human scientists who maintain the laws of Time and Space–and helping them against the mythos creatures, paramilitary mythological creatures who are trying to exist in reality. Sonic briefly altered history so Kintobor never became Robotnik, but had to change it back to stop the mythos creatures altering the Big Bang.
