no you don't trade eggs. you get a riolu from Riley after helping him on iron island
Find riolu at the Tower and Level him up to at least level 36 and then trade him. :)
if u have Pokemon diamond or Pokemon pearl then u can find them underground
the only way 2 get riolu is 2 trade over from diamond, pearl or platinum
Fight everybody in the riolu event and a cherim will be there
You can find it in the Safari Zone or trade it from Platinum, Diamond, or Pearl.
Trade with Pokemon Pearl or Pokemon Platinum
You need to have Pearl or trade with someone who has Pearl.
if you surf in oreghburgh (sp?) there will be a vetrian he will have a riolu
Riolu is one of the more difficult Pokemon to find, you have to place specific items in the mountain zone and wait over a period of three weeks. The easier way to get a Riolu is to purchase a copy of Diamond, Pearl or Platinum (or get a Friend with a copy of one of these games) Trade over a Riolu, problem solved
You Cannot catch lucario on pokemon black the only Way is to trade him or catch a riolu.
You'll need to trade it from Pokemon Diamond, because it isn't in Pokemon Pearl.
Can't find Jirachi without trade or migrate
