The Hexagon Brothers (Japanese: 六つ子ブラザーズSextuplet Brothers) are a team of six Cipher Peons in Pokémon XD. They are named Resix (Japanese: モノルMonol), Blusix (Japanese: ジレルDirel), Browsix (Japanese: トリルTrill), Yellosix (Japanese: テトルTetol), Purpsix (Japanese: ペタルPetal), and Greesix (Japanese: ヘキルHekil). They are dressed in the colors of their names, specialize in a different type of Pokémon, and have a Shadow Pokémon of the corresponding type. The types are Fire, Water, Ground, Electric, Poison, and Grass, and the Shadow Pokémon are Houndour, Spheal, Baltoy, Mareep, Gulpin, and Seedot, accordingly.
The Hexagon Brothers have their own motto, in which they count off. However, they always mess up their counting (e.g. forgetting to count the first person, or counting an extra time after six). They appear at the Cipher Lab and at Phenac City (disguised as the "Justy Gang"). They can be rebattled at the Cipher Lab at any time.
