For me best pokemons are: arceus charizard darkrai garchomp feraligatr giratina lugia ho-oh mewtwo typhlosion
The best Legendary Pokemon with the best stats is none other than Mewtwo.
I have awesome team of magneton, lapras, arcanine, venesaur, alakazam( best Pokemon ever in my opinion), and machamp. all very good also consider legendaries
I wreckon Mewtwo is the best Pokemon to get Leaf Green. You can get after you bring the ruby and sapphire to Celio on Island 1. It is Lv 70 and it is in Cerulean Cave. I got a Mewtwo with around 326 special attack. Mewtwo also has the best recovery move in the game.
