Thank you for the response Max Optimizer. I have one other question. Do Virtual Console Pokémon get exclusive ribbons just for being Pokémon transferred from the VC games like cherish ball event Pokémon? I mean if you check their summary pages will they have ribbons that declare a love for Pokémon or something else.Edit: I just tested this out myself.
In the regular Sun and Moon games, the summary does indeed say "from a distant land".
In the Ultra Sun and Ultra Moon games it says "from the Kanto region" or "from the Johto region".
The Celebi is legit.
