With Sun and Moon kicking off, we were introduced with a group of Pokemon known as Ultra Beasts, one of them being UB-01 which we all know as Nihilego. Nihilego takes a different approach on what we usually see from similar Pokemon with its typing. It has a great offensive movepool while also being able to carry useful utility moves. Its versatile as it can cover different types of roles on teams, all while being just as effective as the last. Its able to keep its place in the OU metagame because of its great offensive pressure, its coverage, specially defensive bulk, and decent speed tier.
Nihilego has a good movepool, giving it different options to run for different types of teams. One of the sets being a Lead, it can reliably set up Stealth Rock, and be able to pressure other common leads such as Landorus-T or Garchomp with Hidden Power Ice.
Nihilego @ Focus Sash
Ability: Beast Boost
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Power Gem
- Stealth Rock
- Sludge Wave
- Hidden Power [Ice]
Standard lead Nihilego set which is commonly found on offensive oriented teams as it puts pressure with its good coverage and can reliably set up Stealth Rock. As mentioned before, this set is commonly partnered with offensive Pokemon that appreciate the Stealth Rock support such as Pheromosa, Salamence, Ash-Greninja and the list goes on. This set is commonly used because of how easily its able to fit onto offensive teams while being able to check a good amount of Pokemon that offense may tend to struggle with.
Nihilego @ Life Orb
Ability: Beast Boost
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Stealth Rock / Toxic Spikes
- Sludge Wave
- Power Gem
- Hidden Power [Ice] / Hidden Power [Fire]
Nihilego can afford to run Life Orb for a noticeable boost in power allowing it to break through Pokemon a lot easier with its great coverage. Running an entry hazard isn't a must if you already have the role covered in another Pokemon as Nihilego can run something different such as Substitute to avoid predicted Thunder Waves or another attacking move such as Thunderbolt to nail Pokemon such as Celesteela or Skarmory. Partners for it that appreciate Stealth Rock being up and can provide momentum for Nihilego to switch in could be Pokemon like Rotom-W (If you want a slower Volt-Switch), forcing your opponent to constantly switch due to your Volt Switch, Stealth Rock damage begins to rack up a lot. For more offensively inclined Pokemon, things like SD Garchomp or Dragon Dance appreciates the threat of bulky grounds such as Landorus-T being weakened or flat out gone and Nihilego does that.
Nihilego @ Choice Scarf / Choice Specs
Ability: Beast Boost

Timid Nature
IVs: 0 Atk
- Thunderbolt / Psychic

- Power Gem
- Hidden Power [Ice] / Hidden Power [Fire]
I haven't used this set yet personally, but this set personally reminds me of how Choice Scarf Pheromosa, due to it boosting its Special Attack in respect to Pheromosa's Attack while still having great Speed. Once it starts getting kills, its damage significantly increases and will be incredibly hard to stop. Due to it lacking Stealth Rock, something such as Landorus-T is necessary as Stealth Rock gives Nihilego the most kill opportunity. Its not much to say about the Choice Scarf set outside of it being a viable revenge killer. I've seen some Choice Specs Nihilego on the ladder, it seemed to wallbreak decently because of how hard it pressures teams because of its wide movepool. As the game progresses, it gets harder to switch Pokemon as you don't want to give it +Special Attack from Beast Boost which would only make it harder to handle.
