Just to be more specific:
[quote]Moves must align with the Pokemon’s type and [b]species[/b]. Starmie cannot know/learn Thunderbolt or Gyro Ball, but can know/learn Water Spout and Extrasensory. [u]Bisharp can learn moves like X-Scissor[/u] and Guillotine...[/quote]

"Species" is where this goes into a gray area. Basically, if you can come up with a "good argument" for the Pokemon to know the move, then I'd be okay with it.

For this specific example: I would allow it since it's thematic that Gengar can be seen as a Pokemon that "Eats Dreams" (even though that's also a Psychic move), and so it would make sense that it can lull targets to sleep. I also have a soft spot for those kinds of "signature moves" some Pokemon have.
I do typically take "inspiration" of Pokemon from their Dex entries - none of which describe Gengar as eating dreams. So that could be an "against" argument - one that I wouldn't take up, myself. If you wanted to adhere to that idea, more power to you.

In the end, there's some "normal" "bleeding" that happens with Dark, Fighting, Psychic, and Ghost type moves and Pokemon. There's quite a bit of thematic/racial overlap with some of them.

A more "extreme" example would be: I would actively [i]encourage[/i] someone to add Extrasensory to Ninetales, due to it's lore and general descriptions (going so far as to make it a Fire/Psychic type...or Fire/Psychic/Ghost type)

An example of a "no" would be Granbull knowing Thunder Fang. How does a fairy dog Pokemon generate electricity?
You can then request to make up a move and call it "Fairy Fang" that has a lesser chance to paralyze (or some other kind of effect) - and I'd say "okay."


As for "starters," they aren't a thing/concept in this world. Your "starter" would be a Pokemon native close to where you lived or a Pokemon you were given as a gift or something.
For example, my character's starter was Surskit because he grew up in Oldale Town.

Also: [quote]- Characters must be 18+. This is not the RP for a child's Pokemon journey.[/quote]

Hope that helps. :)
