This song is a remix of "Opening Stage" from Mega Man X, cuz robots and it fits with his character. NEXUS, or by its government name, 21(x), is the main antagonist of "Box the Drawing," and he was always meant to be a confusing yet somewhat relatable character. If Box's game does well and Nexus is actually liked as a character, who knows, maybe he'll get his own game. The Nexus OST is a side job while working on the official Box OST.
