Slipspace Rift Incident

The slipspace rift incident is an incident caused from the Chat Empire spliting a slipspace crystal, to give it to all of their Administrators. The rift accidentally opened portals from several alternate universes, and Fox was unfortunately sucked into the rift. This is the explanation for Fox's entrance from the Star Fox realm into the Heretic Dinofox realm.
