Leo is the training officer of Holy Angel Castle.
Leo, as Regulumon, makes a cameo, alongside Gabou, as V-Tamer's Yagami Taichi explains to his Adventure: counterpart that they fought alongside the endless hordes of Virus Digimon and could do nothing but seal the polyhedron that caused them to appear. He then properly appears at the end of the chapter as Leomon after the polyhedron was destroyed, badly wounded but happy.
