Taking part early on during the Second Great Dimensional War, Operation Charybdis was a coordinated joint naval assault against the Guardian Units of Nations, or United Federation forces naval assets in the West Coast of Northamer and the surrounding naval ports. Lead by Baroness Scylla Aria Bradanska as she lead the assault against the human forces, unfortunately for Sonic the Hedgehog, the sheer ability for Scylla to submerge under the water to attack ships, her allies near limitless numbers, and Sonic's own inability to swim lead to a decisive victory for the Moebian invaders early on in the war.
