Description:SCP-XXXX is a World War 1 British Brodie Helmet made by ████████ manufactures. SCP-XXXX is 29 cm wide and 11 cm in height. SCP-XXXX was brought to the Foundation's attention after charity workers report digging up the remains of a "forgotten soldier" wearing a helmet "Leaking gas."(later identified as Mustard gas). The charity workers were told that they hit a mustard gas canister while digging up SCP-XXXX. A dog tag was later found on the soldier with the following information "Edward █████, 19 years of age, █████ battalion, ID:█████." Later examination of the body concluded that the dog tag belonged to the body and that his real age is ether 16 or 17. The body of Edward █████ was found holding his neck suggesting he died of mustard gas. It is not yet known if the body possesses any abnormalities yet.
Samples of the mustard gas provided by SCP-XXXX shows no abnormalities but victims of SCP-XXXX are suffocate by there lungs filing with blood instead of oil. DNA testing shows that the blood matches the DNA found in the remains of Edward █████. SCP-XXXX will leak Mustard gas randomly and can last for 1 hr up to 2 months, while not "leaking gas" SCP-XXXX can produce a instance of SCP-XXXX-1 a humanoid figure made of the same gas produced by SCP-XXXX, measuring of to 1.9 meters tall and 0.7 meters wide. SCP-XXXX-1 can under stand and speak English even thought it holds no organs. Some instances of SCP-XXXX-1 will attempt to wear SCP-XXXX, if successful SCP-XXXX-1 will grow in size and is to be terminated if it does not stop growing before growing to a size 5 times its original state.
