In the current set up for the pokemorph setting I have made legendaries are treated as a form of pokemon royalty as they are not only rare they are all members of a set of prestigious families and unlike other pokemorphs their offspring are always going to be the same species as their mother (the one that lays the egg). Due to this and the fact that there are very few female legendaries it's uncommon to see the actual legendary forms and not just descendents of them. In the tournament scene however there is a top ranked team that is nothing but legendaries. Now to clarify a bit more certain legendaries don't have families or anything like that as they are truly one of a kind (Arceus,dialga,palkia, the legendaries from x and y,groudon
And kyogre, and any particular pokemon that is specifically named as one of a kind yes Rayquaza.)
