Pokémon FireRed Tips

catch lagends easy
use a pokemon that knows false swipe and use him first, then make sure that he has 1 hp left and
then use a pokemon that knows sleep powder or hypnosis and use an ultra ball and u have a 72%
chance at catching him.

OH, and i would start with moltres and work my way up 2 articuno then zapdos. but save the game before battling them in case u kill them.
