Special Nidoking
Nidoking @ Life Orb
Ability: Sheer Force
EVs: 4 Def / 252 SpA / 252 Spe
IVs: 0 Atk
Modest Nature
- Sludge Wave
- Earth Power
- Ice Beam
- Thunderbolt
- 69% power boost to all moves at no cost
- Wide, relevant coverage (hits bulky Water types, Steel types, and Flying/Ground types)
- While lower, Nidoking's Special Attack stat is still good, especially with investment
- Utterly walled by Special Defense behemoths, specifically Chansey, Blissey and Umbreon
- Very common set; as such, it is predictable
- Goes off of Nidoking's lower Special Attack stat
Physical Nidoking
Nidoking @ Life Orb
Ability: Sheer Force
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Earthquake
- Poison Jab
- Superpower / Thunder Punch
- Megahorn / Ice Punch
- Goes off of Nidoking's higher Attack stat
- Surprise factor- could hit Chansey, Blissey, ect on the switch
- Outdamaged by Special set due to Sheer Force
- Not all moves are boosted by Sheer Force, specifically Superpower, Megahorn and Earthquake
- Better coverage moves, especially Ice Punch, are weak
- Sacrifices power for coverage or coverage or power
Overall, the Special Nidoking is far superior. All four of its moves are boosted by Sheer Force, making them more powerful than the Physical Nidoking. All four of the moves have good BP and great coverage at the same time, another thing the Physical set cannot boast.
Physical Arcanine
Arcanine @ Life Orb
Ability: Flash Fire
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Flare Blitz
- Extreme Speed
- Wild Charge
- Close Combat
- High BP moves
- Vast, relevant coverage (hits bulky Water types, Normal types and Steel types)
- Access to coveted, powerful priority in Extreme Speed
- Lots of negative secondary effects (recoil, stat drops)
Special Arcanine
Arcanine @ Life Orb
Ability: Flash Fire
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Fire Blast
- Overheat
- Dragon Pulse
- Hidden Power [Rock]
- A more powerful STAB in Fire Blast, as well as a way to nuke the opponent in Overheat
- Extremely shallow Special movepool, resulting in terrible coverage
- Goes off of Arcanine's weaker Special Attack stat
Not much to say here. Arcanine has a terrible Special movepool which results in poor coverage, leaving it unable to touch many Pokemon who resist Fire. Meanwhile, its Physical movepool offers great coverage, a powerful STAB move, and priority in Extreme Speed.
