It is shadow ball, I'm still tryna find out where to get it though.
Shadow Ball is at Celadom City Game Corner... you can get it for 4,500 coins
beat morti in ecruteak city and he will give you tm30:shadow ball The TM shadow ball can be obtained in firered or leafgreen by using your game corner coins to buy it, you can't get shadow ball in ruby and sapphire or emerald.
You can find it in the top floor in Mt. Pyre just go down the stairs near the hole that makes you fall through the floor. There should be a Poke Ball thingy containing TM30(Shadow Ball).
I don't think Persian learns it naturally. Only by TM30.
have a Pokemon emerald trade to ruby/sapphire, which then R/S trades to leafgreen. i don't think you can catch Rayquaza in Ruby, but I know Emerald is easier.
go to one island Mt.Ember you can find them there in the lvl.30's
TM30 Shadow Ball is found on Route 210 or buy spending BP in the Battle Frontier shop.
Yes you can trade leafgreen version Pokemon to another leafgreen version.
s orry mate u can't
Norman is not in leafgreen.
Firered and leafgreen both can catch different Pokemon but there pokedex is the same, here is some examples: magmar only in leafgreen not firered, oddish in firered not leafgreen, ekans in firered not leafgreen, bellsprout in leafgreen not firered, pinsir in leafgreen not firered.
in leafgreen u have to get it from a Nintendo event and in sapphire after u get it in leafgreen u trade it from leafgreen to sapphire
It doesn't. You can teach it Shadow Ball with TM30, or have your Misdreavus level up to level 37 before evolving it.
