Vivillon

Vivillon sits at a marginal 0.38 percent usage and rank 109 in singles, a fringe support attacker. Its bug and flying typing grants full immunity to ground, quarter resists to fighting and grass, but double weaknesses to fire, ice, electric, and flying, with rock as a four-times weakness. The 50/50/50 defenses leave it fragile, and it relies on Quiver Dance boosts to power Hurricane and Bug Buzz.

Playstyle：The single set revolves around stacking Quiver Dance turns and switching between Hurricane and Bug Buzz. Leftovers at 67.8 percent sustains longevity while Lum Berry at 23.7 percent patches up the self-inflicted sleep from Sleep Powder. Timid max speed is the default, and Compound Eyes at 99.1 percent makes Sleep Powder highly accurate, paired with Substitute to create uncomfortable pressure. The leading spread funnels 32 speed and 28 special attack EVs to outpace the metagame and retain offense.

Doubles is where Vivillon finds its niche at 3.33 percent usage and rank 41. Its 89 base speed slots into the upper-middle tier of the format, and the Focus Sash at 87.1 percent versus Choice Scarf at 12.6 percent divide it into two clear roles. The bug-flying typing nullifies ground entirely and resists fighting and grass, sparing it from Earthquake and Grassy Glide.

Playstyle：Doubles play centers on redirecting attacks with Rage Powder at 24.1 percent and setting Tailwind at 6.8 percent, while Hurricane at 21.7 percent brings heavy flying-type damage. The 24.1 percent Rage Powder and 23.1 percent Sleep Powder make it a premier redirect-and-control piece, with Protect at 19 percent providing a turn of safety. The dominant 57.3 percent spread pours into max speed and 32 special attack to outpace opponents before clicking Hurricane.
