Dustox
Bug - Poison
60/50/70/50/90/65
Shield Dust: Damaging moves used by the opponent will no have a secondary effect.
Compound Eyes(DW): Raises the Pokemon's accuracy by 30%.
Level-Up Moves:
TM moves:
Notable Gen 4-only moves:
Notes:
Bug-Poison Typing: With the abundance of Fighting moves and the growing threat of Grass and Bug moves, Dustox's typing is great for tanking these types of hits since Dusty here 4x resists all three of them. Although Dustox's typing is it's only saving grace and the only reason you should be using it in OU at all.
Reliable Recovery: Roost helps ease a bit of the damage Dustox will undoubtedly be taking for your team. It also helps that it resists some common moves.
A Great Ability: Shield Dust is something most players don't expect, mostly because they don't even know what it does. Not only are you immune to T-bolt, Ice Beam, Flamethrower, and Iron Head hax, you're also immune to Scald's burning effect.
Bad Stats and Movepool: Despite the good ability and typing, Dustox has pretty low stats everywhere and it's move pool is pretty shallow and dosn't give it many options.
Possible sets in OU:
- Heavy Dancer
@ Leftovers
252 HP/ 252 Defense/ 4 Sp.Attack
Bold or Modest
- Bug Buzz
- Quiver Dance
- Roost
- *Filler Attack*
Trying to abuse Dustox's typing and somewhat decent bulk, you can set up a sweep after a couple of Quiver Dances.(And by a "couple", I mean 6)
With no haxy burns from bulky waters using Scald, you can boost up your Sp.Attack and Speed to usable levels whilst also having a huge amount of Special Defense. Immunity to Toxic and T.Spikes along with roost to heal off Stealth Rock is fantastic. For attacks, you can't really do much. No matter what you do, you'll be walled by something as Bug + Anything is never good enough, though I like to use Hidden Power Ice/Sludge Bomb for Dragons.
- Stalling in Fear
@ Leftovers
252 HP/ 252 Speed/ 4 Sp.Defense(Not 100% on the Speed)
Bold or Calm or Timid
- Toxic
- Protect
- Substitute
- Roost
A nice little Toxic stalling set that's possibly out-done by something else, but Dustox's typing might be better as it can give you a free turn.
With Protect, Substitute, and Roost to keep you healthy, Toxic stalling something like Tyranitar shouldn't be too difficult as Stone Edge is bound to miss with the Substitutes.
I know Dustox's stats seem terrible, but many also thought Quagsire's were terrible and look at him taking such powerful hits now.
Even if Dustox is barely used, maybe it has a niche in OU with its typing.
Please Discuss possibilities if any at all for our little forgotten moth friend.
