The two captured EB-06 Graze units, belonging to Orlis Stenja and Crank Zent, were unusable because some of their parts were severely damaged, but Tekkadan mechanics, Nadi Yukinojo Kassapa and Yamagi Gilmerton, managed to combine all the usable parts to create a new single mobile suit, dubbed the EB-06/tc Graze Custom. When Graze Custom's Ahab Reactor frequencies were scanned, it registers as Crank's unit. This indicated that the suit uses the reactor from Crank's Graze.

While Tekkadan's mechanics have very little experience working with mobile suits, the Graze's series design focus of easy maintenance was a great help to them. During the assembly of the Graze Custom, some of the Grazes' damaged parts like the head, shoulders and torso were replaced with Tekkadan's own custom parts. A booster was also added to the back, improving the suit's thrust. These new parts are painted mostly in white as that is the cheapest Nanolaminate Armor paint color. The upper body armor's strength has dropped compared to the original, but since the suit is lighter overall, its mobility and turning is expected to be better in space.
