An interdimensional entity who hails from the VOID, X is a being whose fascination with humanity and the Sonic franchise created a destructive mix, forming a vessel for an entity whose goal is to spread and cause as much pain and suffering as it can go. It does this by playing various games, some subtle in its sadism, but always rigged to torture and manipulate the players that it forces into these games, using the souls of its new "friends" to fuel the vessels to play its games over and over again.
