Quick answer

The memorable boss content sits around the AI weapons — Pupa, Chrysalis and Cocoon — building to the Peace Walker fight itself, with Monster Hunter-style large-monster hunts in Extra Ops. Names follow the original 2010 release; 2026 specifics are being verified.

The AI weapons

Peace Walker's trademark boss battles are the AI weapon vehicles: Pupa, Chrysalis and Cocoon. Each is a large mechanical foe with its own behavior, typically requiring heavy weapons and good positioning.

The Peace Walker

The climactic fight is against Peace Walker itself, the walking-warship AI that gives the game its name, and the emotional peak of the story.

Crossover & large monsters

Beyond the main AI weapons, Extra Ops include large-monster hunts (including the famous Monster Hunter crossover) that are best tackled in co-op, blending boss combat with the mission structure.

Co-op & boss fights

Boss missions support online co-op (up to 6 players per official materials), so many players team up to farm phases and ranks. See the co-op guide for online details.
