You can get Rayquaza on the Last Second floor of Sky Pillar :) It takes time, Depending on your luck tho :) Good luck finding it, Its lvl 100 and the items, Moveset, EVs Are randomized every time you get it but the IVs are always 6x26 :)
You can't delete characters that you have made but you can get 4 badges of kanto and travel to hoenn via the boat in Vermillion city, You need pokemon emerald rom :D
