The Joes returning from Trucial Abysmia meet the newest Joe, Mongoose. Another Joe team is sent to Darklonia to investigate a Revanche project. Dr. Venom rebuilds the Brainwave Scanner and designs a Blue Ninja to house what the Scanner had recorded of Snake Eyes' mind. Cobra tries to assault the Dreadnoks but Zartan is prepared and ambushes the Nightcreepers sent to kill him. Obake Obaasan brings Dawn to Tokyo and gives her a variant of Snake Eyes' uniform.
