if you mean legendary then here we go, about 7 i think because there are
rayquaza
groudon
kyogre
latias/latios
regirock
registeel
regice
CAUTION! all of these Pokemon are extremely hard to catch without a master ball!!!
bu ive caught all of them except latias because you can only catch one or the other.
after you beat the elite 4 you will go to the tv in your house and watch it, your mom will ask you what color a mysterious flying Pokemon is red or blue.
if you answer blue, it will be latios or the blue Pokemon, if you answer red, it will be latias, or the red Pokemon. but one more thing, THERE IS NO SPECIFIC PLACE THEY ARE HIDING IN, IF YOU ENCOUNTER ONE IT WILL BE A COMPLETELY RANDOM ENCOUNTER!!! so be ready with a wobbufet or trapinch with the ability "arena trap" AT ALL TIMES!!! i had a wobbufet and master ball ready and randomly and FINALLY found it then caught it. sorry for the long story but i hope i helped! ;)
P.S. when i said "AT ALL TIMES" i meant it.AT ALL TIMES NO MATTER WHAT!
no one freakin cares
you can catch sudowoodo and smeargle

It is very rare but you can catch it at mount Pyre.
