Zygarde 50

Using Zygarde 50 in a Playthrough

Zygarde is a Dragon/Ground Legendary built from Zygarde Cells and Cores and can exist in 10% Forme, 50% Forme, Complete Forme, and now Mega Zygarde. The 10% Forme is the fastest at base 115 Speed but has only base 54 HP and 71 Defense; 50% Forme rises to 108 HP and 121 Defense with base 95 Speed; Complete Forme reaches an extraordinary base 216 HP while retaining 121 Defense and dropping to base 85 Speed. Aura Break reverses the normal power boost from Fairy Aura and Dark Aura, while Power Construct changes a 10% or 50% Zygarde into Complete Forme when its HP falls to half or below under standard ability-enabled mechanics. Thousand Arrows is the family's defining Ground move because it can hit Flying-types, Levitate users, and targets holding Air Balloon, removing one of Ground's normal defensive answers; Extreme Speed, Dragon Dance, Coil, Thousand Waves, Outrage, Core Enforcer, Glare, and Rest add physical, special, or support options. Complete Forme can Mega Evolve using the Zygardite in Legends: Z-A; Mega Zygarde has 216 HP, 216 Special Attack, and 100 Speed but lower Attack and defenses than Complete Forme, and Core Enforcer is replaced by Nihil Light while Mega Evolved. Legends: Z-A itself does not use Abilities, and no ability-enabled Mega Zygarde is currently confirmed, so the Mega should not be assigned an invented Ability. Dragon/Ground is immune to Electric, resists Fire, Poison, and Rock, but is weak to Dragon and Fairy and takes quadruple damage from Ice.

Zygarde 50 in Competitive Pokémon

Zygarde's competitive history changes dramatically by generation and form. In XY, only the 50% Forme was available; it spent most of the generation in UUBL because base 100 Attack and 95 Speed made it look underwhelming beside Garchomp, although its bulk, Dragon/Ground STAB, Dragon Dance, Coil, and Extreme Speed still gave it real OU niches. Sun and Moon transformed Zygarde into a metagame-defining threat by introducing Thousand Arrows and Power Construct: Thousand Arrows bypasses ordinary Ground immunities, while Complete Forme's 216 HP makes it one of the bulkiest Pokemon ever used in standard formats. Power Construct Zygarde proved too strong for OU and became an Ubers fixture, where defensive Coil, Dragon Dance, Glare, Rest, Thousand Arrows, and other sets could pressure both offense and balance. The 10% Forme developed a separate lower-tier identity as a very fast Choice Band or utility attacker because base 115 Speed and Thousand Arrows compensate for its low bulk. Mega Zygarde is too new for an honest long-term singles history; current canon gives it a radical special-attacking stat shift and Nihil Light, so it should be presented as a new Legends: Z-A form rather than retroactively assigned an established competitive resume.

Zygarde is unusually forgiving if Legendary Pokemon and form mechanics are allowed. The 50% Forme already has strong physical bulk, while a Power Construct Zygarde effectively gains a huge amount of maximum HP when it changes into Complete Forme after falling below half health, creating a dramatic emergency durability boost. The 10% Forme is much frailer but can avoid attacks through base 115 Speed, making it better suited to quick offense than prolonged tanking. Thousand Arrows is exceptionally reliable because it removes the need to predict around Flying-types or Levitate, while Coil can increase Attack, Defense, and accuracy at once for controlled physical setup. Ice attacks are the critical danger to every form because they deal quadruple damage, and strong Fairy or Dragon attacks are also dangerous. Mega Zygarde's 216 Special Attack creates enormous offensive potential, but its Defense and Special Defense are lower than Complete Forme's and its strongest new mechanics are specific to Legends: Z-A, so it should not be treated as simply a bulkier Complete Forme.

Zygarde 50% Forme is the large serpentine body originally encountered in Kalos and is created from roughly half of Zygarde's available Cells. It monitors ecosystems and emerges when it detects serious disruption to the balance of nature. Pokédex lore describes it as merciless toward anything that threatens that balance, while its many hexagonal components emphasize that the body is a coordinated colony rather than a conventional single organism. In Kalos, this form is strongly associated with the mysterious depths of Terminus Cave and with observation rather than constant intervention.
