Good Moveset/Nature

[Doom]

What's a good moveset/Nature for Riolu/Lucario. It's level 1 with max ev's except 1

In the future, please do read the descriptions of individual sections, this kinda stuff is supposed to go in the Team Showcase section.

Anyways, IMO, there's multiple sets Lucario can run because it's got quite a few options. You can make it a special set with Agility and/or Nasty Plot, physical set with Agility and/or SD, and just 4 attacks. Barring Radomus, every single gym leader boasts rather fast teams, certainly faster than Lucario's base 90, so Agility or a priority move are a must. Lucario can every unboosted foe after a single Agility and it gets 3 very good priority moves, Vacuum Wave and Bullet Punch as STABs and E-Speed. SD/Nasty Plot + 3 attacks is the best way to go IMO. While 110/115 base is very good, it's not quite sweeping levels.

It honestly depends on what your team needs, but I'd recommend Nasty Plot, Aura Sphere, Shadow Ball/Flash Cannon, Vacuum Wave or SD, High Jump Kick, Crunch, Bullet Punch/Extreme Speed. Ghost+Fighting is better coverage than Fighting+Steel and hits everything neutrally, the loss of STAB is a good trade-off for better coverage and you can just keep boosting if need be. Fighting+Dark is only resisted by Fairies which are hit SE by Bullet Punch, but E-Speed is overall stronger, with the things that resist it much more often than not being slower than Lucario and being weak to one of your other moves, so the choice of the priority move there is up to you.
