>>29991835>>29991894Mythical is the official term for event legendaries and has been in use since Gen 5 with Victini, although the term was around and distinct for much longer in Japan. ("Phantom/Illusory" Pokemon is what they call them)
What makes them distinct is that they are:
1. Not required for the Pokedex to be considered complete.
2. Automatically banned from battle facilities and VGC, even in the years where they let mascot legendaries play.
