- “ An O2 Mask! Now I can finally breathe underwater! ”
- ―Ratchet, upon finding the O2 Mask [R&C (PS4)]
The O2 Mask was an item attachment for the Ranger Armor which allowed for breathing underwater. This was accomplished though providing the wearer with a supply of oxygen by synthesizing and recycling it. Ratchet discovered the O2 Mask, which the Blarg had stashed while exploring the Pumping Stations, on Pokitaru.
