Grease's cyan and black-coloured final form accessed by inserting the North Blizzard FullBottle into the Blizzard Knuckle, before attaching it into the Build Driver, known as Gekitō Shinka. This form is themed after a robot and ice. The FullBottle and adaptor for this form was created by Sento Kiryu to be used only as a weapon, as, if used to transform it would kill its user, Kazumi Sawatari. This form debuts in Episode 46 of Kamen Rider Build.
