I can think of plenty of ideas for the pokemon and sailor moon crossover.



for one, you are a trainer who moved to tokyo. instead of choosing one starter, you can pick three starters out of all the start pokemon, one for each type. and you can capture pokemon and train.



your adventure will be to help the sailor scouts save earth from queen beryl. the nega monsters are battled the same way as pokemon, but cannot be captured. they have their own moves and they have types. and when you battle them, they have the stats boosts at the start. think of the cross between pokestar enemies and totem pokemon.



there will be a special female Gardevoir that can change the look to resemble one of the sailor scouts, have new type and a exclusive move:



Moon form: psychic and fairy. Move: moon wind

mercury form: water and fairy. move: mercury tidal

mars form: fire and fairy. move: mars burn

jupiter form: electric and fairy. move: jupiter storm

venus form: fighting and fairy. move: venus smash



the generals are fought too. they will have the nega versions of the pokemon and the strongest ones will be themselves.



the ultra beasts appear as the monsters brought to tokyo by queen beryl to look for the rainbow crystals. they must be captured in order to obtain the crystal. and the ultra beasts can be used once captured.



the legendary pokemon of the game will be an angered rayquaza after Darien(under the brainwashing spell) tried to control it and you have to capture it.



queen Beryl has two battles. one where she is fought like a legendary pokemon. she has 5 nega pokemon to use before you fight her herself. and second fight is when she turns into Super Beryl with stat total of 780. and you can use mega rayquaza and any pokemon on your team to fight her



for optional fights, you can battle the sailor scouts and tuxedo mask themselves.



what do you think?
