Yes it has to be at (least)1-1.5 to evolve
Yes, because it is more powerful when it evolves into a Lucario than just staying a Riolu.
None of the older Pokemon have Pre-evolutions or evolution in Black and White, including Lucario.
You can breed Lucario with Ditto or trade for more, but you can't actually catch any more.
Depends on the level but Riolu evolves into Lucario when it has high enough freindship and learns beter moves. That is true but I think Riolu is cooler than Croagunk so.. Riolu is better!!
Riolu does not learn "Aura Sphere", as it is not in its learnset. To get Riolu to learn "Aura Sphere", you must evolve it into Lucario. Lucario learns Aura Sphere sometime in level 30-40. If you are higher than that, simply go to Electivire Link Shop
This means a Pokemon will evolve during a trade some example Pokemon that evolve during trade are: Haunter, Graveler, Machoke. There are plenty more than that so keep trading.
No, it is a fully evolved Pokemon. For the record, no Pokemon has yet been known to evolve more than 2 times like Pidgey to Pidgeotto and Pidgeotto to Pidgeot.
Be specific. What pokemon? ---------------------------------------- Most of them evolve at level 16 than level 36 :)
Nidoking is the final evolution of the male Nidoran, so no, it will not evolve. Pokemon have no more than three evolutionary stages, if any at all.
You can still just click "Evolve."
trade from diamond pearl or platinum other than that just use cheats
Most of them.Pokemon like Absol, Lengendary Pokemon, and several others don't evolve. But most Pokemon can evolve at least once if they haven't already. Pokemon never evolve more than three times. Additionally, some Pokemon evolve with use of an item, by trade, by "friendship evolution" (utterly trusting of trainer) or by other means. There's even a Pokemon that evolves when you train it in a particular place, Eevee. Threre are also several other ways to evolve eevee. Short and sweet answer: Most Pokemon evolve.
