How to get Lucario in Pokemon Platinum?

Sorry to ask, but how can I obtain Lucario in Pokemon Platinum?

Thanks.

You go to Iron island and meet up witha person name Riley.

Doesn't he only evolve during the day too?

make sure you have an empty slot because he's going to give you an egg. that will hatch Riolu and you have to evolve it by making it happylucifer3999

various things make a pokemon happy. you can take it to a place to get massaged, enter it in competitions and win, just keep it in your party, or just train it, it will evolve in no time. just make sure you do it during the daylucifer3999

You get an egg from Riley one of your partners in Iron Island that gives you an egg for Rioliu and then you have to friendship evolve it into Lucario.

I'm trying to mate My Lucario with Ditto. BUt for some reason it doesn't get along with any of them. Does Lucarios Nature determine whether or not it will breed? Or in other words do pokemon natures determine if they will breed? (had the same issue with Scyther)DarkRavenWyng

Both Lucario and Scyther should be able to breed with ditto, regardless of their natures. After you put both Pokemon in the daycare, talk to the man just outside to see how well the Pokemon get along.

1. If he says, "They seem to get along very well," than there should be around a 70% chance of the Pokemon producing an egg.

2. If he says, "They seem to get along," than there should be around a 50% chance of the Pokemon producing an egg.

3. If he says, "They don't seem to like each other," than there should be around a 20% chance of the Pokemon producing an egg.

4. If he says, "They prefer to play with other Pokemon than each other," than there's a 0% of the Pokemon producing an egg.

As long as he says one of the first three messages and not the fourth, than your Pokemon will be able to produce an egg. After every 256 steps the Pokemon may produce an egg; however, the chances will differ depending on how compatible the 2 Pokemon are.
