In the manga/anime series Sgt. Frog, an addiction to Gundam models is the only thing stopping Keroro from invading Earth, since he reasons that if the Keronians invade Earth, all of the Gundam models will be destroyed, and there will be no one to make new ones. He loves the models so much, if any harm comes to them, he will react violently (such as going Super Saiyan). He is prepared for such events, though, since he keeps spare kits in the Hinata family's attic. Because the anime is made by Sunrise (the makers of the Gundam anime), and because Bandai is the show's primary sponsor, the show is able to refer to Gundam models directly without legal issues.
