An au I've been thinking about where Arceus makes the creation trio have human fragments to learn more about them and the humans motivates. He end up falling in love with a certain Subway master when he moves his company HQ to nimbasa city.

Ingo is tall but "Icarus" is almost a foot taller.

The creation trio are managers under Icarus and don't know he's Arceus, he thinks they already know.

Also Tina is the only one who chose a gender, she really liked how Akari looked. Diana and Pike don't want or need their gender and Arceus goes along for convenience.
