Chesnaught

Mega Chesnaught sits at 64 speed and almost never moves first in 64-speed metagames; it holds a 0.09% single rating at rank 173, firmly on the fringe. Its real selling point is the Mega-boosted 122 defense layered with Bulletproof, letting bulky teams scout Flying-type attacks and clean up physically frail threats like Archaludon and Aegislash behind Iron Defense stacks. The 107 offenses and 64 speed are too low to break walls with Wood Hammer alone, so most sets lean on teammate support or a one-shot Belly Drum.

Playstyle：Body Press leads at 16.8% with Iron Defense close behind at 13.6%, forming the Iron Press core: stack defenses first, then retaliate with Body Press. Seed Bomb (7.9%), Rest (7.9%), Synthesis (7.3%) and Spiky Shield (6.4%) build the recovery and defensive utility layer, while Drain Punch (5.4%) offers Fighting-type coverage and Belly Drum (5.1%) unlocks a one-shot nuke. Top spreads are Impish 32/2/24/0/8/0 at 31.7%, Impish 32/0/32/0/2/0 at 17.3%, and Adamant 32/32/0/0/2/0 at 14.6%: the two Impish sets bulk physical defense to wall physical breakers, while the Adamant set dumps everything into Body Press damage.

At 0.24% usage and rank 133, Mega Chesnaught remains a fringe pick in doubles. Its value lies in double-specific utility: Spiky Shield at 20.7% shuts down contact moves while Wide Guard at 11.9% blanks spread moves, and Iron Defense (6.6%) plus Body Press (20%) form a defensive pivot. The 4x Flying weakness and 64 speed leave it vulnerable to priority Flying-type hits and fast offensive teams, and its modest offenses keep it from threatening walls on its own.

Playstyle：Doubles movesets diverge from singles: Spiky Shield climbs to 20.7% as the top pick, joined by Wide Guard at 11.9% to build a protection grid, while Wood Hammer at 15.3% becomes the primary offensive hit. Drain Punch (5.1%), Leech Seed (4.8%) and Seed Bomb (2.7%) round out the utility and filler slots. Spreads skew toward Relaxed 32/0/8/0/26/0 at 23.6%, dropping speed to underspeed common threats; Impish 32/0/8/0/26/0 at 10.6% and Relaxed 32/0/32/0/2/0 at 7.4% follow the same bulk-maximizing line.

Chesnaught sits at 0% usage in the singles ladder, unranked. Even the broader 0.2% figure keeps it on the fringe. A 122 base Defense paired with Bulletproof is a credible physical wall on paper, yet 64 base Speed and a 75 Special Defense leave it outclassed.

In doubles Chesnaught holds a 0.02% share at rank 253, deep in fringe territory. Bulletproof is locked in at 96.2% and Leftovers at 91.3%, fixing its role as a physical tank and support piece. Holding both Spiky Shield and Wide Guard lets it answer spread damage, which is the niche it actually occupies.

Playstyle：Body Press at 23.0% is the main offense, and pairing it with Iron Defense at 18.7% converts the 122 base Defense into real damage. Wide Guard at 20.4% and Spiky Shield at 17.4% form the protective backbone, the former blanketing Rock Slide and Scald-type spreads, the latter punishing contact. Leech Seed at 6.9% plus Leftovers handle sustain, so most turns are spent soaking hits and forcing switches. The 47.5% Impish 229/0/252/0/27/0 spread maximizes that 122 Defense with the rest into Special Defense, a textbook utility build.
