Portal Weapon

The Portal Weapon (Japanese: ポータル武器, Pōtaru Buki), also known as the Portal Device (Japanese: ポータルデバイス, Pōtaru Debaisu), is a device invented 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. This device was given to Mr. White by Mr. Nash in the Japanese dub. In the English dub, it was left to Mr. White by  Guardian Boreas, which he kept in his Shop of Wonders.
