S.O.N.I.C.X.

The Society for Observing and Neutralizing Inter-dimensional Creatures and Xenomorphs (S.O.N.I.C.X.) is a secret organization that was only seen in the Sonic X' mangas. It was created by an unknown leader called "The Organizer" (whose face is always hidden by shadows) with the purpose of destroying Sonic the Hedgehog and his friends, due to them ruining their lives somehow.

Role
The organization was never presented in the anime, though three members are seen. In the manga, they tried many tactics to destroy Sonic, but they never succeeded.
