Ultra Q
The second movie features "Digital Kanegon", which is a take on the original Kanegon from "Ultra Q". It also features Kohji Moritsugu (Dan Moroboshi from "Ultra Seven") as Captain Ban Satsuma. The running joke is that he frequently lets slip that he knows that we in the audience know that he's Mr. Moritsugu/Dan Moroboshi/Ultraseven. He says "Natsukashii! (how nostalgic!)" when he sees Capsule Monster Miraclon. At the end of the movie, he also nudges Katsuto and tells him he'll have to teach him the heel drop sometime, which implies that Dan knows that Katsuto is really Zearth.
