Heavy Phazon Canister

These large canisters are a common sight on the Space Pirate Homeworld, and are used to hold large quantities of Phazon. They are highly volatile and are usually seen being moved by Pirate Cargo Drones via a grapple beam-like device.

Logbook entry
Metroid Prime 3: Corruption: "Heavy Phazon Canisters are used by Space Pirates to transport large amounts of Phazon. Unlike the smaller versions, these are made and reinforced with durable metals. Only a strong impact will destroy them."
