You didn't really say how to remove the name. To do that, delete all letters and hit enter or, name the Pokémon the name of it's species (Like naming Toucanon, Toucanon. Just don't evolve this Pokémon... I don't think it's like that). You should also start your answer with, "If you're not the OT of the Pokémon you're trying to nickname". OT means Original Trainer. Also "can not" should be "cannot". The rest of your answer is fine though. You should also make it clear that the old dude is inside the building or even give a link to a video. Aren't I nice?
