Meganium

Mega Meganium holds a 3.9% usage rate at rank 45 in singles, slotting in as a mid-speed special attacker. The ability Mega Sol sets permanent sunlight on switch-in, removing the need for a dedicated weather setter and turning it into a self-contained weather core. Compared with other popular Mega options in the format, its 80 base Speed is slow, but 120 Special Defense and 100 Defense let it absorb special hits comfortably. The five-element weakness profile (fire, ice, poison, flying, bug) leaves it vulnerable to physical priority and super-effective coverage, which is the core tradeoff.

Playstyle：The movepool is anchored by two STAB options: Solar Beam at 24.3% fires at full power under permanent sun with no charge turn, while Weather Ball at 24% flips to a Fire-type nuke in sunlight, doubling its effective output against Steel and Ice targets. Encore at 10.6% and Leech Seed at 11.4% provide utility to punish passive switches. The 45.3% lead spread is Modest 28/0/0/32/0/6, pushing Special Attack to maximum and grabbing a small Speed bump to outpace most mid-tier threats sitting in the 70s. Top teammates are Garchomp at 13%, Mega Starmie at 8.9%, and Toxapex at 8.9%, covering ground-type offense, ground immunity with recovery, and toxic-spike hazard setting respectively.

Garchomp

Doubles usage sits at just 0.65% at rank 83, a fringe pick. Its 80 base Speed is on the slow side for the doubles metagame and cannot naturally benefit from ally Tailwind support without sacrificing turn order elsewhere. The five-type weakness grid is more punishing in doubles where two opponents can layer coverage. Protect at 22.7% shows the user base understands the need to survive turns, but staying alive long enough to swing requires allies that draw opposing aggression, which the format does not always provide.

Playstyle：The four lead moves in doubles are Solar Beam 24.3%, Dazzling Gleam 23.4%, Protect 22.7%, and Weather Ball 22.7%. The first two carry STAB coverage; Dazzling Gleam is especially valuable in a Fairy- and Dragon-heavy doubles meta. Protect at 22.7% sits essentially tied with Dazzling Gleam, signaling that self-preservation is weighted equally with AoE offense. The 9.9% Timid 2/0/0/32/0/32 spread pushes Speed to +2 for turn order priority; the 8.5% Modest 32/0/0/32/0/2 spread maxes HP and Special Attack for raw burst. Top teammates are Pelipper at 9.3%, Basculegion at 8.6%, and Archaludon at 8.6%. Pelipper sets rain on switch-in, which overrides the sun, yet Weather Ball still flips to Water-type under rain and keeps the offensive plan intact.

Meganium records a 0% usage rate in singles with no ladder rank, drawn from only 18 recorded matches. The 80 base speed forces it to move after most threats it would want to check, and the fire, ice, flying, and poison weaknesses leave few safe switch-ins. Without a clear offensive niche in the current singles landscape, it has no place in typical builds.

At 0% usage in doubles with no rank, Meganium sits well outside the metagame, yet 327 matches reveal a coherent support identity. Protect, Giga Drain, Leech Seed, and Ingrain form the sustain core; Knock Off disrupts item-dependent foes and Dazzling Gleam patches the dragon-type blind spot. The item distribution is telling: Leftovers 34.6%, Big Root 23.2%, Sitrus Berry 10.1%, Miracle Seed 9.8% together cover nearly 80% of sets, all built around longevity and grass-type amplification.

Playstyle：Meganium operates as a support pivot rather than a damage threat. Giga Drain and Leech Seed create dual recovery layers, amplified by Leftovers and Big Root, while Ingrain prevents forced switches and denies phazing effects. The standout observation is the stark split between singles and doubles: Counter appears at 23.6% in singles but does not surface in the doubles movepool at all, confirming two completely different roles. Choice Scarf at 6.1% is the rare pivot pick, aiming to outspeed key targets with team support.
