It's 30 December 1999. Utsumi and Bud have returned to Japan to challenge the SV2 again, and sell their team's services in the format of the Griffin. At the SV2, the AV-Zero is going though its paces. It has been improved and is now much faster. Kanuka has returned to Japan to visit her grandmother and has dropped by to visit her former colleagues at the SV2. Detective Matsui discovers that several top Labor specialists are in town and informs Captain Goto of his findings. Meanwhile, Momoko Sakurayama receives a tip-off that several arms dealers are also in Tokyo. She informs Kumagami, who in turn tells Captain Goto. Something big is going to happen. That night the Griffin Labor returns. Division 2 was previously called out to a fire, so Division 1 is called in to deal with the Labor. Bud soon figures out the Zero's weakness: it is programmed to stop near buildings to avoid damage. He takes full advantage of this and defeats both Patlabors.
La Seconda Squadra Veicoli Speciali disinnesca una bomba dovuta ad un atto terroristico mentre il Griffon torna in azione nella baia di Tokyo e batte facilmente gli AVZero, detti anche Peacemaker, del primo plotone.
世界各地から続々と大物レイバー関係者が結集したある晩、東京湾に正体不明の黒いレイバーが出現した。迎え撃つべく出動した第一小隊と最新鋭機AVゼロ・ピースメイカーの面々は目を疑った。彼らの前に現れたのは、かつて“イングラム”との死闘の末、バビロンの城門に沈んだはずの“タイプJ9-グリフォン”だったのだ!!
