Charizard-Fire/Dragon Actually makes sense.
Ninetales-Fire/Psychic Not sure about that one. Don't know why.
Golduck-Water/Psychic Definitely supporting this.
Arcanine-Fire/Dark(because it's ninetales counterpart) I wasn't sure about Nintetales but I refuse a Fire/Dark Arcanine. Why ? Because just no.
Farfetch'd should return to normal typing Fighting/Flying is awesome and makes him different to the other birds.
Marowak-Ground/Fighting I'm not hostile to the idea...
Kangaskhan-Normal/Fighting He doesn't need it
Electabuzz-Electric/Fighting Debatable.
Magmar family- Fire/Poison I seriously don't even know how you got that idea. Learning poison attacks doesn't make them a poison Pokémon.
Pinsir-Bug/Fighting Heracross is enough.
Gyarados-Water/Dragon Makes sense too.
Porygon family-Normal/Electric Makes sense, definitely supporting this.
Mewtwo-Psychic/Dark Interesting, but no. Otherwise we should give every cruel Pokémon a dark type.
Noctowl- Flying/Psychic Debatable.
Sunflora- Grass/Fire?? Already asked. I'm not hostile to the idea though.
Dunsparce-Normal/Ground Makes sense.
Granbull- Normal/Dark See Mewtwo.
Ursaring-Normal/Fighting Well, Drayano gave a fighting type to Beartic, so...
Donphan-Ground/ Rock or Steel He doesn't need it.
Stantler- Normal/ Psychic or Grass Definitely not grass. Psychic, however...
Azurill- Normal/Water Makes sense.
Mawhile- Steel/Dark Makes sense too.
Spinda- Normal/Psychic?? Yeah, no. I think the best idea for Spinda would be no type at all.
maybe add Dark to Zangoose and Seviper
