Finally, another one gets introduced to Mr Brush....
MK 16 'The Fire Rescue model.....

This model is made from an extremely heat-resistant alloy and usually has the appearance of wearing the uniform of a traditional Firefighter, with a yellow 'helmet' making them very distinct in an emergency situation They also feature a removable fireproof 'cloak' that can be wrapped around a living creature that is being carried to safety from a conflagration, whilst the detachable 'mask' on their 'face' can deliver a supply of whatever combination of gases are needed to keep the rescued alive.
This model was originally designed to have a yellow 'helmet' for easy identification, but as this always blackened quickly when in use the black variant was adopted instead....
