The Storm Fighter is a Ninja vehicle owned by Jay. It resembles a blue and gold-colored fighter jet that is surrounded by electricity during flight. The Storm Fighter can be summoned by focusing one's mind on a weapon (in Jay's case, the Nunchucks of Lightning).
Jay first transformed his Nunchucks of Lightning into the Storm Fighter in order to retrieve the Fangpyre Staff, which he succeeded, so that the venom inside would cure his parents from permanently becoming Serpentine themeselves. However, he lost his concentration, causing the Storm Fighter to vanish and Jay to fall down.
Jay used his Storm Fighter to travel to Ninjago City in order to infiltrate a Serpentine congregation. However, he needs to take Kai as his passenger since the latter was blinded by a Venomari's hallucination-inducing acid.
Rise of the Great Devourer
Jay used his Storm Fighter to catch up to the Serpentine Bus as it travelled to the Lost City of Ouroboros.
