スワームチェンジ (Power Construct)

Power Construct is an exclusive ability that triggers a dramatic transformation for Zygarde when its health drops below 50%. Upon activation, both 10% and 50% Zygarde forms will instantly transform into Complete Forme, gaining significantly enhanced stats and a massive boost to their bulk and offensive capabilities. This transformation occurs immediately when the HP threshold is crossed, making it one of the most impactful mid-battle form changes in competitive play.

The ability is completely unique to Zygarde and comes with several protective measures built into its design. Power Construct cannot be copied by abilities like Trace or Role Play, nor can it be suppressed or replaced through moves like Skill Swap or Gastro Acid. This ensures that opponents cannot prevent or steal this powerful transformation mechanic. Once Zygarde transforms into Complete Forme, it maintains this form for the remainder of the battle, regardless of healing.

In competitive contexts, Power Construct has created interesting strategic dynamics where Zygarde becomes increasingly dangerous as it takes damage. Opponents must carefully consider whether to finish off a weakened Zygarde quickly or risk facing its much more formidable Complete Forme. The ability effectively gives Zygarde a second life in battle, transforming what might be a disadvantageous position into a potential comeback opportunity. This makes Zygarde with Power Construct a unique threat that requires special consideration in team building and battle planning.
