Only caveat, No legendries lol......
Who is your starting 6 Pokémon, across all gens? Personally........
Dragonite: I just like this Pokemon's look and tanky-ness. This thing usually eats super effectives, and can fire back one-shotting the target.
Machamp: Imo, any 90's kid will like Machamp, because he is Goro-esque.....Also, Revenge.
Charizard: Charmander was the first Pokémon I ever used. The reason I played through red in the late 90's was to see Charizard lol.....Balanced Pokémon imo.
Duraludon: Steel Dragon is an interesting typing, and he looks like a skyscraper dragon.....I mean.....
Kingdra: After I fought Clair, immediately went hunting for a Kingdra myself.
Sceptile: He is really fast, and mega can change the game vs a fire type.
What 6 Pokémon would you put up against a gauntlet of every gym & elite four-esque trainer, across all gens?
