So i heard if u breed two riolu u get one riolu. What if u breed rainbow riolu do you get rainbow riolu?

you only get normal or shinies from breeding.

also you cant breed with any "Baby pokemon", you must use their evolved to breed.

here are some baby pokemon:
Riolu
Chingling
pichu
budew
togepi
Elekid
Magby
Smoochum
munchlax
bonsly
happiny
mantyke

there might be be more but i cant think of anymore.

You can only breed Riolu, if you have a Female Lucario of any color! As baby pokes cannot be breeded with baby pokemon! You must have the evolved form of the pokemon and it must be female.

Oh i see. Can we use a ditto to breed with other pokes to obtain egg pokes?

soory, we cant used ditto to breed with, da man decided against it, so whatever pokemon you uses as the female, the egg will hatched into that pokemon.

one more question can we breed legendary if they have genders?

the only legendary you can breed so far is Manaphy, and you get a Manaphy in return.

i dont think you can breed legendaries other than manaphy as then people would be breeding arceus and ohter poke like zapdos and people wont spend 1250 coins to buy it from the games corner

Also one more question
can we breed unowns?

u can cannot get coloured pokemons but u can get shinies but luckily and in legendaries only manaphy can breed

You cant breed unowns!

can i breed a happiny?

According to what i know now. no it has to be a blissey and a female
