The very existence of Iron Bundle is proof that something exists in the far future of the Violet Book beyond unfeeling machines and militarism. Delibird is no one's idea of a war pokemon, and its longtime association with festivals strongly suggests that someone, at some point when it was possible to mechanize pokemon, thought it worth their while to use robotics to enhance a cultural event (if an occasionally violent one) which still existed in their time.
The two accounts of contact with Iron Bundle do not describe any look into its bag, so we can only speculate on what constituted a 'gift' in this time period; archaeologists have learned realms of information from the presents of the past, so what might we learn from the blue bag of the future? The white light from within the bag, combined with this pokemon's frequent use of Electric Terrain, suggests some kind of electronic handheld gaming system, perhaps a successor of modern devices from the Game Boy to the Switch; theories to this effect have led gamers, more than even futurists, to become fascinated with this pokemon. A rival theory, however, claims that this bag contains the souls of naughty children.
Iron Bundle's attested use of water attacks has been explained as part of a cooling system, or as future levels of global warming leaving the climate too cold for any pokemon to be a true 'ice' type in the sense of the present era. It has been widely interpreted as a memory of when Earth was a water planet, a more justified Team Aqua, and a tiny bit of protest against the mechanization of the planet.
Then again, a rival theory holds that it was built by the Machine Empire's Queen Promethium as a festival gift for her daughters.
