The Porygon Conversion move
Variations of copying pokemon moves, like Sketch, Mimic, and Sketch2
Copy the pokemon's stats to Ditto permanently.
Auto-Transform ability.
Good Ole Deoxys-ish forms(Ditto is a DNA pokemon)
Absorb the Life force out of other pokemon, like an amoeba or virus(A protoplasm)
They should do with Heracross/Scizor/Pinsir with what they did with the Hitmons, link them with a pre-evo. Tauros and Miltank also need the same thing, maybe a calf pokemon with an ambiguous, unknown gender? Azurill often switches genders on evolution, why not do it with other pokemon as well? Tauros has a high attack while miltank is more defensive, and a buffalo pokemon (that can either be male or female) if stats are equal would be nice.
the part were it transforms permanitly would be cheating to get a rare pokemon
even though it wont show up in pokedex
Well, it wouldn't neccesarily be completely permanent. It wouldn't have the stats of the actual pokemon, and would have to faint constantly to make it back into it's original form.
As for actual pokemon, Cthulhu is just DIEING to be a legendary pokemon. He's perfect for the spot. All that Nintendo needs to do is change his design a bit(make him more pokemon-ish), and his name to Zhqulqa, or something similar, yet hard to pronounce.
Here's what Cthulhu looks like.
Plus, Pokemon is very lacking when it comes to squids and octopus pokemon. The only ones out there are Octillery, which evolves from an unrelated remora, and tentacruel, which is a jellyfish, but jellyfish are barely related to Squid. There's glass squid, giant squid, cuttlefish, cosmic alien squid, and just the regular nonremora octopus to mess around with.
However, there are also many possible legendaries(I love the current pokegods; Groudon, Kyogre, Rayquaza, Diaruga, and Parukia) and regulars to mess around with. Parrotfish would be good. They could have 2 cosmic pokemon to rule over creation and the world's destruction; and Team Nova/Abaddon working together to try to harness both of their powers to destroy and recreate the world/universe. Also, an actual Dragon trio would be nice.
I would like the next generation, Pokemon Ebony/Ivory, or Pokemon Arsenic/Hydrogen or whatever they choose, to have a darker yet awesome-like-Scizor atmosphere in terms of how pokemon are designed, maybe taking inspiration from mythology, fiction, religion, the artist's pure imagination, and how God would think up a creature into existence(think elephants; and then think pokemon. Pokemon excels at novelty).
