Nuzlocke with randomized flying pokemon encounters/catches.
My first Pidgeotto owned Brock.
Lost four bros and one sis so far.
The sis was a Dratini, to a Pidgey. She would have died anyways.
One of my bros fell to Misty. It was a Doduo.
But I still won.
Lost my Charmeleon to a Aerodactyl.
Currently getting my other bros to Level 25 or 30 before going into Diglett's Cave and the cruise ship.
I still have that Zubat, who is now a Golbat. And could evolve except I don't have the National Dex.
So here's a Zubat.
