No, the only way to get them is to migrate them from the 4th generation games.
you need to have atleast beat the Pokemon league once in dimond and you should be able to migrate.You also need either emerald version, Sapphire version, or ruby version catch regice, regirock, registeel then migrate into dimond version
pokemon white is hareder than pokemon black

To
Braille, there is no language called "regi" , regi are the three legendary rock Pokemon and regigigas.
There are four Regi pokemon. They are Regirock, Regice, Registeel, and Regigigas.
Use it on any legendary that is hard to capture, like a Regi or the version exclusive.
== == Yes because in this game you can get rayquaza, kyogre, and groudon. and I don,t know if you can get regi ice, rock, or steel on the other games.
