Jousun (ジョースン Jōsun?)[1] is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, swordfish-based Badnik model created by Dr. Eggman.



The Jousuns resemble green swordfish with a rocket thruster on their belly.


The Jousuns only appear in Ocean Base. In gameplay, they lurk just outside the Zone's climbable waterfalls, hovering up and down and waiting for their victim. Once the playable character gets in their line of sights, they will surround themselves in a green energy field and charge into the playable character at high speed, inflicting damage. Because of their placements and fast attack patterns, they can be tricky to avoid.
