Pokémon Pelipper

[TTK]

Type: Water/Flying
Abilities: Keen Eye / Drizzle / Rain Dish
Stats: 60 HP / 50 Atk / 100 Def / 95 SpA / 70 SpD / 65 Spe

Notable Attacks:

• Weather Ball
• Surf
• Hurricane
• U-turn
• Roost
• Knock Off

Pros

• Is the better of the two rain setters for Champions OU as its slow pivoting in U-turn allows its teammates in freely without them risking damage.
• Reliable recovery alongside good physical bulk lets Pelipper stay around to come in to bring back Rain if it has ended.
• Typing offers key resistances to Ground, Fighting, and Fire.
• Enables Swift Swim Pokemon like Basculegion-Forme and Archaludon.

Cons

• Damp Rock not being legal means rain is only 4-5 turns in the grand scheme of things instead of 8 turns, reducing its effectiveness in neutral matchups.
• Pelipper is Stealth Rock weak and cannot even run Boots to alleviate this issue.
• Poor special bulk while taking rocks damage doesn't help at all.

Pelipper needs to invest in its bulk to improve its longevity switching in multiple times to enable rain while being bulky enough to tackle physical attackers that it is able to check like Garchomp and Sneasler. Hurricane is Flying STAB targeting Fighting types like Sneasler and Roost is mandatory to keep Pelipper's HP up. U-turn is required to give free turns to Pelipper's teammates to get in safely. Its low Speed tier allows it to U-turn second after Pokemon like Corviknight. Pelipper doesn't necessarily need to run Water STAB considering the partners that you will pair with it are often running Water-type moves so Knock Off is an option to annoy its defensive switchins like Galarian Slowking.

Partners
/ - These mon's viability hinges on the rain playstyle thanks to Swift Swim doubling their Speed and increasing their damage output. Pelipper also is neutral to Grass so that helps.
- Archaludon can reach its fullest potential in rain since its signature move Electro Shot has no charge time under rain and defensively, Archaludon handles both of Pelipper's weakness to Rock-types like Tyranitar and Electric-types like Rotom-Wash. Pelipper also handles Archaludon's weaknesses to Ground and Fighting.
- Mega Meganium benefits from Rain reducing its Fire weakness while Meganium defensively protects Rain teams from Electric types. Meganium's ability also means its Weather Ball's damage is not reduced in Rain and it still benefits from 2/3 healing from Synthesis. Pelipper can check Pokemon like Scizor, who is able to revenge kill Meganium with Bullet Punch

Checks and Counters
- Rotom-Wash resists Pelipper's STAB moves and threatens the OHKO with STAB Volt Switch.
- Slowking is not taking much damage from an uninvested Pelipper and Sludge Bomb does quite a bit to Pelipper. Galarian Slowking does not like taking Knock Off but as it's typically Colbur Berry and Pelipper's Attack stat is so low, Slowking is not taking much damage at all. Slowking also removes rain via Chilly Reception, really hindering the playstyle.
Special Attackers - Some of the tier's strongest special attackers like Mega Alakazam, Mega Charizard Y, Mega Floette, and Dragapult can easily dispatch Pelipper after Stealth Rock with their STABs or coverage.
