Lucario mates with what Pokemon in platinum?

Answer 1

A Lucario can breed with a ditto, another lucario, and, but be warned, unless you have a female lucario, you will not get a riolu out of an egg, but any Pokemon in the Human like egg group, such as croagunk or toxicroak, machop or machoke, jynx or electabuzz, or a Pokemon in the field group, like torchic or combusken, stunky , buizel, or even empoleon, or prinplup. Happy breeding!

Answer 2

Lucario of either gender can mate with a Ditto and a female Lucario will need to mate with either a male Lucario or a Pokémon from the Field or Human Egg Group. Pokémon from the human egg group would include ones such as Machop, Abra, Hitmonchan, Mr. Mime, Himtonlee, Kadabra, Alakazam, Machamp, Machoke, Jynx, Magmar, Electabuzz, Hitmontop, Electivire, Magmortar, Hariyama, Sableye, Makuhita, Medicham, Meditite, Croagunk and Toxicroak.
