|“Yes! Yes, that's it! The gate is open! We are ready . . . for Unagami to enter Ninjago!”|
|— The Mechanic|
The Manifestation Gate is a gateway that was built by the Mechanic and his henchmen in Ninjago, and Unagami and his Aerial Drones in Prime Empire. It serves as a portal between Prime Empire and Ninjago, and is powered by Zane, though that almost killed him.
The Mechanic's Henchmen begin building the Manifestation Gate in order to bring Unagami to Ninjago. The Mechanic then demands for the Prime Empire Motherboard, but Zane claims it was destroyed. Knowing Zane is lying, The Mechanic brings in Wu and threatens to hurt Wu if Zane doesn't confess. Zane ends up revealing the motherboard, and The Mechanic inserts it into the gate. He then uses Zane to power the gateway although it had a high chance of destroying him.
When P.I.X.A.L. is fighting The Mechanic's Henchmen, the gateway is opened and The Mechanic waits for his master to arrive.
Once Unagami has managed to get into Ninjago, The Mechanic and his henchmen ran away in fear. Luckily, P.I.X.A.L manages to free Zane just as Jay arrives to help. The latter then comes up with a plan to have Unagami and Milton Dyer reconcile at Borg Tower which then causes all of the trapped and cubed players to be released through the gate alongside the NPCs. It is unknown what became of the gate.
