Okay, unfortunately, you can't get Registeel on Pokémon Diamond, or Pearl. You will have to migrate Registeel from Pokémon Sapphire or Ruby (possibly Emerald). Hope I helped-PokéFan
As a side note, there may be an extremely rare chance that you find someone that has Pokemon diamond AND a Movie Regigigas. If they transfer the movie regigigas over to their platinum version, they can capture regirock, registeel and regice, and therefore allowing you to trade with this person.
Ninjask doesn't evolve.
you can't in diamond without migration, however you can get them in platinum by trading the event lvl 100 regigigas form diamond or pearl to platinum, then they will appear in certain rooms that were once empty. Regice: in mt. coronet on the way to snowpoint city Registeel: at the final room on iron island before you go outside Regirock: unknown. sorry is that for platimun or diamod??

Registeel is a Steel type pokemon.
Registeel is not in the Sinnoh Pokedex. :)
Registeel is not catch able in Pokemon LeafGreen. In order to get a Registeel you will need to trade for one from Pokemon Ruby or Sapphire.
