SCP-XXXX
'The Blitzkrieg'
Description:SCP-XXXX is a humanoid figure with a similarity with a 30 year old man. He's 6' 6" tall, and weighs 47.8 kg. The clothing of SCP-XXX is similar to that of a man's clothing in the 1940s. It seems to be a black blazer made of an unknown material similar to cloth, with a white trenchcoat of the same material, and a shirt of cloth. Their trousers are again, made of the unknown material, with white leather shoes of similar style to those of the 1940s. Since they seems to be distressed without it, SCP-XXXX is allowed to carry a Walther P38, a 9mm common Nazi hand gun. Their skin tone is of a pale man, although very skinny, and their hands are similar to that of a guitarist. They are also permitted to have a Les Paul 'Log' in the same room as them since it doesn't seem to have any supernatural qualities. SCP-XXXX's face is, once again, very shrunken. He has ruffled black hair and is clean shaven, though he seems to be forever sweating. SCP-XXXX mostly speaks German, but can speak fluent English and little French.
SCP-XXXX has type 3 burns across his body, all of which would have killed a human. His face lacks a nose, it has been cut straight off. An eye has been replaced by pure stainless steel; it seems they cannot see from it. His right arm is made completely made of scrap metal, all of which is of the Messerschmitt Bf 109, a German fighter plane used in WW2. X-Rays confirm SCP-XXXX has no skeleton of bones, but rather a crude version made of stainless steel. A kidney, their liver and their large intestine are all crude mechanical versions run on fuel, entering via a tube which runs through their body, and leaves through another tube similar to an exhaust pipe. It has been confirmed that, with enough fuel, SCP-XXXX can become similar to a superhuman, but doesn't choose to do so. SCP-XXXX claims to be 156 years old, and that their real name is Günter Alscheid.
Containment:
SCP-XXXX is to be held in a standard humanoid containment room in Area 13, with restrictions upon entertainment. SCP-XXXX is allowed to roam around light containmet areas, cafeterias and break rooms, as long as they tell a facility guard first. They are allowed to walk around the grounds, but are not permitted near the gate or other areas. They are rarely allowed to perform to staff. Their Walther P38 is to never be loaded, though rounds are permitted to be held in a bag in their containment room, and no more than 18 9mm rounds on person.
Note: After Interview Log 12, all flamable materials in SCP-XXXX's room are to be ensured to be covered in heat resistant and non-flammable materials.
Addendum:
SCP-XXXX has revealed in an interview that they died, assassinated during WW2 by a French spy. After the pain of the knife wore off and they 'died', they woke up again, almost instantly, in a trash heap. A note on their forehead simply told him: 'Zweiter Versuch', which translates into English as 'Second Try'.
Addendum:
SPC-XXXX was seriously angered during an interview. They ended increasing their body temperature to 250°C, and fire started from their metallic arm, exhaust pipe and blocked eye. Every time they spoke, sparks would leave their mouth. Their fuel consumption, however, greatly increased, and SCP-XXX apologised extremely afterwords.
