Everyone calling it the "Poor man's god" and the "Fake Arceus God", I can imagine the pokemon concerning about all this and wondering who Arceus even is personally, and is he really a fake, getting possibly emotional about his purpose in life, hoping there's more ot his existence than being "false/nothing".
