Gringat's first home was on an island named Poliaz, where he worked as a general handyman and liked to tinker with machinery in his spare time. After a while he became incredibly skilled with machinery, and left to the island of Xia to ply his trade as a weapon and vehicle engineer. His GringatTronics line became fairly popular until he lost business to Nuparu's Vahki and the matoran Ferrum . Unbeknownst to him, many of his designs were also stolen by Makuta Raximoras.
