Next of all, I don't want any of the starters to be dually typed with the new type(s). Give some strong (good stat layout) and well-designed Pokémon the new types so it would be accepted easier. Scizor, Steelix, and Sneasel were really good new typed Pokémon, even though their final evos shined in 4th gen (Weavile).
Yet we have Normal beasts like Arceus (originally a Normal type), Slaking, Blissey, and Snorlax, strong Bugs like Scizor, Volcarona, and Forretress, and un-aggresive-looking/feminine Fighting types such as Riolu, Breloom, and Mienshao.
So you can't generalize a type on what it sounds like.
