Greninja

Mega Greninja sits at 4.11% usage and rank 42 in singles. Protean reshapes its offensive typing on contact, and 122 Speed lets it pressure most matchups before they react. Five weakness slots (electric, grass, fighting, bug, fairy) define what threatens it, while resistances to fire, water, ice, dark, steel, and ghost give it room to switch in. Every recorded set holds Greninjite and runs Protean with no deviation.

Playstyle：Mega Greninja plays as a fast special attacker with output built around two speed-leaning spreads: Modest 32 SpA / 32 Spe (50.9%) and Timid 32 SpA / 32 Spe (23.5%) together account for over 70% of sets. Ice Beam, Dark Pulse, and Sludge Wave each take roughly a quarter of the move slot, covering dragon, fairy, and grass targets together; Water Shuriken (14.6%) rounds out the set. The plan is to strike first, lock in Protean's STAB, and leave the opponent without a clean response.

At 0.36% with rank 110, Mega Greninja barely registers in doubles. Protect becomes the most common move at 22.5%, followed by Dark Pulse (17.4%) and Ice Beam (8.7%); Blizzard (8.4%) replaces Water Shuriken for spread damage. The shift away from the singles-oriented three-STAB core toward Protect and Blizzard reflects how doubles pressure pulls the set into a support-leaning role.

Playstyle：The doubles default is Timid 32 SpA / 32 Spe (41.6%), keeping the speed-first identity from singles. The higher Protect share and Blizzard inclusion push Mega Greninja toward a pivoting-support role rather than the singles sweeping plan, though its low overall share means there is no single dominant doubles build.

Greninja sits at 2.32% usage in singles, ranked 58th. Protean dominates the ability slot at 79.3%, and the entire set revolves around the type-change pivot; Torrent at 20.7% banks on chaining Water hits for the boost. Focus Sash (82.8%) is overwhelmingly the item of choice, which fits the Protean hit-and-run profile: lock in a defensive or offensive type on entry, survive a heavy hit on the sash, then use the 122 base Speed to dictate the pace. The role is tempo attacker — win exchanges through type advantage and speed rather than raw bulk.

Playstyle：Dark Pulse (23.2%), Water Shuriken (20.5%), Sludge Wave (19.1%) and Ice Beam (13.9%) form the core coverage spread — STAB plus the right holes: Water Shuriken for multi-hit chip and rain-synergy damage, Dark Pulse for Psychic and Ghost targets, Sludge Wave covers Fairy, Ice Beam nails Garchomp and Dragon-types. Icy Wind at 9.9% is a utility pick, used to cut opposing Speed rather than deal damage. Spreads split between Modest (39.8%) and Timid (38.3%) — the divide is whether to push Speed past the 122 base threshold or trade it for Special Attack. Top teammates are Mimikyu (13.1%) and Archaludon (10.1%): Mimikyu patches the Fairy blind spot, Archaludon answers Fairy and grounds the team against Ground-types that threaten Greninja.

Greninja sits at 0.09% usage in doubles, ranked 194th — effectively absent from the format. The moveset is fragmented: Ice Beam 15.0%, Dark Pulse 10.7%, Low Kick 10.4%, Hydro Cannon 9.9%, Rock Slide 9.6%, Protect 9.6% — no move clears 15%, and there is no agreed-upon template. Naive spreads (22.2% and 14.4%) point toward a mixed-attacker build that uses Protean to turn into a Fighting-type for Low Kick, but the 0.09% usage shows this line has not been competitive enough to stick.
