Its status within the Sonic the Hedgehog canon (aside from its Sonic X incarnation) is that of a worldwide military/emergency law enforcement federation, somewhat similar to NATO and Marvel Comics' S.H.I.E.L.D..

It is sent to capture Sonic the Hedgehog after he is suspected to have stolen a Chaos Emerald and attacked G.U.N. forces while escaping, when in reality he was mistaken for Shadow the Hedgehog.
