Pokemon peral gender change?

I got a girl Lucario! yeha how i don't know only a 12.5 chance i want it to be a boy how do i do that?Pokemon peral gender change?
Breed Lucario with a Ditto, to obtain a Ditto you have to go to route 218 and use a pokerader, there is a 22% chance of ecountaring a Ditto.... Well you have to get a national dex first...and have you got that? Well you just got a Riolu..so? Well the only way is to

1)Use something like Action Replay

2)Get a National Dex (see all pokemon in sinnoh + beat ellite four)

3) Get traded another Riolu....from the global trade station...

4.......Restart the game...lol

5)Pray to god, and hope that somehow your female Riolu strangely turns to a male....

6) Act like this is all a dream....Pokemon peral gender change?
Sorry. You'll just have to breed it to get a boy. Use a ditto.
the only way i know is to breed your lucario with another to get eggs that hatch into a baby riolu which will most likely be male. you can also breed lucario with a ditto. and if your desperate i can trade you a male riolu. just name the pokemon you want to trade.
if u want you can trade use a action replay or use a ditto to breed its quick to hatch it.
i can give u a boy lucario, i have 3 so its no big deal
