Ummm . . . is this normal?

I was doing my usual Link Battles on the Nintendo Switch when playing Pokémon Violet and I recently saw something very interesting. Apparently, sometimes when I battle, I can find Arceus just chilling in the schoolyard. Is this normal or is this some sort of glitch? I recently just beat Pokémon Legends: Arceus, completed the Pokédex and everything, and transferred both the Arceus I obtained from PLA and Brilliant Diamond to Violet, but I'm not sure if this has anything to do with it. I've never seen this happen before. Has this ever happened with any of you?

it's definitely a glitch.

It's a pretty funny one though you have to admit

It's not really a glitch, Arceus is just omnipresent...

No, that is weird, not really sure why that would happen? Unless it actually was some kind of Easter Egg built into it when you have an Arceus?

I've seen a screengrab of someone battling Penny, with Arceus behind her lol
So I kinda think Easter Egg? (Gonna get my shiny one and try it in case its a glitch and they patch it)
