Transdimensional Portal

The Transdimensional Portal (Japanese: ポータル, Pōtaru, Korean: 포탈) is the device that can be used to travel from Quarton to Earth and vice versa. This allows the Tenkai Knights to travel from Earth to Quarton. It also allows any Corrupted soldier to go to Earth, after Vilius gained control of the portal's power. Guardian Boreas is the Guardian of the Portal, and it is inferred that he gave Mr. White a portal for the Tenkai Knights. The portal has shown to malfunction at times, such as when Vilius attempted to gain its power and Boreas attempted to destroy it. There are many side effects of the malfunctioning portal, such as being taken to alternate dimensions. There are three known portals in the universe, the one in Mr. White's Shop of Wonders, the one at Beni's warehouse, and the one at the Guardians Sanctuary, now commanded by Vilius.

Mr. White's Shop of Wonders
There is a Transdimensional Portal located in Mr. White's Shop of Wonder's basement. The portal there is similar to the one at the Guardians Sanctuary, big with a silver iron like design and blue markings on it. This portal is specially designed for the four Tenkai Knights, with a spot for each of their core bricks. After their core bricks are placed in the portal, they are zapped with a beam of light, and their body turns into respective color cubes. They then transform into the Tenkai Knights.

Guardians Sanctuary
The portal there is similar to the one at in Mr. White's Shop of Wonders, big with a silver iron like design and blue markings on it. This portal zaps the Quartonian and turns him back into core mode, then changes him to a robot on Earth. If the Guardians are using this portal, however, it turns them into a hologram on Earth. It allowed the Guardians to travel to and from the different worlds before Vilius captured it. Now it serves as Vilius's portal to transport his soldiers to Earth.

Beni's Warehouse
The last known portal is at Beni's Warehouse. This portal has never been seen, but instead the users are zapped with a blast of green light and then transported to Quarton.
