Use master balls. Use a ton of ultra balls and put them to sleep or paralyze but master balls are your best bet since leaf green is harder than its original counterpart
Use a moon stone on it.
You have to use Pokeballs, Great Balls, Ultra Ballsect.Many Pokemon can't be caught in Leaf Green, like Mew unless you go to an event, but all events for Leaf Green and Fire Red have ended.
i think a Oddish or Vileplume could use it
Rock smash
you should use 15 premier balls and 2 pokeballs, use premier ball first than pokeball
Weaken it to red HP, paralyze it or make it sleep then use many ultra balls.

Either use a masterball(not recommended) or use status effect like sleep or paralysis and LOTS of ultra balls
use your balls
There is only one Masterball in every Pokemon game.You can't. The only way to get 2 master balls is to use game shark or action replay ect.
Just throw a some Ultra balls, Heal balls, Luxury balls, Premier balls, standard Poke balls, and Dusk balls if you're in a cave or capturing the Pokemon at night. Keep throwing the same kind of Poke balls until the Pokemon can get out very easily, then use a different kind. This might take a while. It's easier if you capture the legendary Pokemon at night, so more Poke balls are effective. (Dusk balls)
Use the pokeflute.
Use a gameshark
If there in the way of your path then use the pokeflute.
Weaken it to red hp, paralyze it, use loads of ultra balls or premier balls to get it.
