It's a long shot, but it's technically possible to have this Mr. Mime. You need to catch/breed it in a Gen 2 game with the OT ASH and ID 31121, nickname it something that will trigger the in-game Gen 7/8 censored words blacklist, trade it to a Red Version game through the Time Capsule, train it up to Lv. 50, then make it go through Poké Transporter.
