"Pokémon ultimate monotype run through"

I would like to play through Pokémon gens 1-9 including arceus but with the 1 same type through all the games starting in order with gen 1 Aka fire red if you have any ideas on a type I should do please let me know. I want you guys to decide because when I do one on my own I can’t normally decide I hope you guys understand and will help me with this quest of mine. Obviously no types like dark which ain’t in Pokémon fire red please and thank you (p.s im switching the game from fire red to regular red)\ via /r/pokemon https://ift.tt/QUBjhHS
