Why does lucario have a terrible defence/sp. defence?

I found my Lucario’s defence is awful. But I love it so much and I don’t want to replace it. But I may aswell have to.Also, what fighting type should I replace? (include movesets please…)thanks guys xD~MysteriousLucario

Well, it doesn’t really need those Defences due to the fact that it is a Sweeper.Sweepers don’t need Defence and Special Defence.

They just need Attack/Special Attack and Speed.Its Typing (Steel/Fighting) grant it immunity to Poison and 9 resistances.

If you want a Bulky Fighting type:

Conkeldurr: SubPunch set is the best.

It has awful defences because that’s how Gamefreak designed Lucario. Besides, its steel typing means it’s resistant to 9 moves & immune to toxic, so it’s meant to a fast sweeper that can take resisted damage rather than a tank.

If you want a bulky Fighting Type, there’s Hitmontop

Ability: Intimidate/ TechnicianItem: leftoversEVs: 252 Sp. Def, 128 HP, 128 AtkNature: Adamant~ Bulk Up/ Fake Out~ Mach Punch~ Stone Edge~ Bullet Punch

Standard set for Hitmontop; bulky, and if you want you can put Rapid Spin on it too.

OR

Item: Choice BandEVs: 252 Atk, 252 Speed, 4 HP~ Close Combat~ Mach Punch~ Bullet Punch~ Pursuit/ Stone Edge

This isn’t a common set for Hitmontop; most people go for a Bulk Up set because they want a Rapid Spinner, but I’m going on the same principle as Technician Choice Band Scizor (who has a slower speed than Hitmontop anyway).

And Scarfty

Ability: Shed SkinItem: Leftovers/ Chesto BerryNature: Adamant/ CarefulEVs: 252 Sp. Def, 128 HP, 128 Atk~ Bulk Up~ Crunch~ Drain Punch~ Rest

This is my favourite Scrafty set; forget Moxie, it’s not fast enough for that. Also, one Will-O-Wisp and its sweeping set is finished. With a few Bulk Ups, it will be able to take x2 weakness hits with ease, and Rest + Shed Skin is there to replenish health and continue sweeping.
