Cross-Z's second final form, known as Galactic Invincible Muscle Guy, accessed by inserting the Muscle Galaxy FullBottle into the Build Driver, merging both Ryuga Banjo and Evol into a single Rider. This form is themed after a dragon, astronomy and a black hole. The FullBottle for this form was created by Sento Kiryu after Killbas attacks the New World. This form debuts in Kamen Rider Build NEW WORLD: Kamen Rider Cross-Z.
