No.
It takes about 80,000 steps for the bad mew egg to hatch.
In the Pokemon LeafGreen video game, Mew is not obtainable through an egg. Mew is a Legendary Pokemon which has only ever been available to players through Nintendo-sponsored special events, and is unbreedable. It is possible to receive glitched eggs called "Bad Eggs" which may corrupt LeafGreen's data, but this is rare.
You can't get mew in firered or leafgreen.
mew and mew two
mew and mew two
There is no Mew 3.
Mewtwo? Plus you cannot get Mew in Leafgreen or Firered.
Since Mew is a legendary pokemon, it does not have a gender, so you cannot hatch an egg. If you want a Mew, you have to use an action replay code or trade it from another game.
You can't catch mew on leafgreen you need gameshark codes for that
