That question was answered many times, except the question was never asked. There are still millions of Pokemon left to be discovered, and you just have to find them. In other words, you will never know how many legendary Pokemon there are until you finish the entire game. (Which took me a few days to finish!) There are many lengendary Pokemon! There are a lot of other lengend Pokemon when you have the national pokedex!
In total including event only Pokemon there are 10.
There are 2
Only 1.
Not including Kanto Pokemon their are 235 pokemon in the National Dex. With Kanto Pokemon included their are 386 pokemon in the entire pokedex.
Of the many Pokemon that you can't get in leafgreen are: Ekans, Poliwag, Scyther, Delibird, Oddish, Murkrow, Growlithe and many more. Edit: Poliwag can be found using a super rod in the pond at route 6.
