Trocra in Hunters

Trocra are crystal structures created by cynobacteria found during the fight with Gorea. Gorea will throw them at Samus or they can be destroyed for health.



  1. "These crystallized colonies of cynobacteria are highly unstable, and will detonate when they contact a solid surface. Avoid contact." — Logbook "Trocra" (Metroid Prime Hunters)
