In the prototype of Mega Man Star Force, Geo had a different mugshot, however, the likeness of this mugshot is used in another game. Like the Battle Network games before it, Star Force has a crossover feature with Lunar Knights, a spiritual successor to the Boktai series. In Lunar Knights, Geo's mugshot resembles the one found in the prototype. The Mega Man sprite, however, is much closer to Star Force's final mugshot.
