Portal Weapon

The Portal Weapon (Japanese: ポータルの武器, Pōtaru no Buki) is a rare device that can be used on Earth to transport anything that originates from Quarton back there. A core brick must be placed in it and it will take five minutes to charge up. This device was given to Mr. White by Guardian Boreas, which he kept in his Shop of Wonders. Guardian Boreas claims that this is one of the most powerful weapons on Earth.

In the Series
The Portal Weapon was first seen in "Elemental Knights", where the boys used it on Slyger to send him back to Quarton.

In "No "I" in Team", Toxsa was holding it and was trying to find a way where it could be immediately used instead of waiting for it to charge up.

In "Corrupted Earth", the boys used it on Granox to send him back to Quarton.

In "Fight Knight", the boys used it on Granox and Slyger to send them back to Quarton.

Trivia

 * It is unknown if Toxsa fixed the Portal Weapon so it wouldn't have to charge for 5 minutes after every use.
