Oh, almost forgot something else I'd like to bring back, but once again, it is technically a rule change. Actually, this time it is strictly a rule change; in the early days, even though you could retreat as many times as you wanted, you had to flip a coin to successfully retreat while Confused (and if you failed, no more attempts with the Confused Pokémon). You had to pay any Energy you for the Retreat Cost before trying. Now that we only get one manual retreat per turn... for some reason you retreat without flipping. This was the great nerfing of Confusion! The earliest dual-Typed Pokémon I recall - and I'm not counting stuff that had like an attack, Pokémon Power, etc. that faked it - were some (but not all) of the Team Aqua and Team Magma Pokémon, followed closely by the Rocket's and Dark (as in that was part of the name) Pokémon which represented Team Rocket in the EX (Gen III) era. [D] Types remained [D] Types, [C] Pokémon became [D] Pokémon, and everything else gained [D] Typing in addition to their normal Typing. I could be mistaken - I can't remember if a few or all-but-a-few Evolving lower-Stages retained their natural Typing. Edit: Oh, and note that prior to their Gen III return, Dark (in name) and Rocket's Pokémon (plus the oddball "Team Rocket's Meowth") were not dual-Types. If you look up Dark Vileplume (Team Rocket 13/82, 30/82), for example, it is purely a Grass-Type.
