Per 
Special Containment Procedures: SCP-5616 is to be contained in a 15 x 7.5 x 3 meter cell, with the following additions:
- One kitchen cupboard
- One standard oven (Can be any brand, 5616 has no preference.)(Oven is to remain unplugged, can
- only be plugged in during testing due to a potential fire hazard.)
- One bench One non magnetic bench (5616 cannot have a metal bench, see Incident 5616-1.)
- 35 slices of bread, any kind
If any of the above malfunction or run out, these are to be resupplied/restocked within 12-18 hours to prevent SCP-5616-1 from manifesting. Any manifestation of SCP-5616-1 is to be reported to security immediately. If 5616 shows any sign of severe distress, it is to be asked the reason for it. The reason given should be fulfilled to prevent 5616-1 from appearing.
In the event of 5616-1 manifesting, security personnel are to guard the chamber doors, and keep them locked until the requested item is at the chamber.
If 5616 leaves the chamber, the zone it is in is to be locked down, and it is to be locked in whatever room it exited into. This is to be continued until the requested item is deposited into the room. If this escalates into the door system failing, the on-site warhead is to be detonated as a last attempt to destroy 5616-1.
Description: SCP-5616 is a biped humanoid resembling a human, but with a toaster replacing his head. The toaster has no markings, being completely smooth and having no manufacturer’s logo, and is made of an unidentified material. Toaster is colored a light blue, but seems to change gradually to a dark blue depending on the specimen’s mood. The organism seems to be able to speak, despite having no visible speaker or mouth. 5616 claims to be named “Toasty”, and also claims to be named by a ‘Broken Shard Security’, and has said that it’s preferred pronouns are he/him. When asked to elaborate on this ‘Security’, it says that it will not divulge information to unknown organizations. No apparent gender is seen, as the body of 5616 is made of the same material as the ‘toaster head’. The body is colored the same as the head, and will change colors with it. The ‘toaster head’ has two eyes drawn on its ‘front’ in permanent marker, and the eyes move like normal eyes.
5616 does not require sleep, but does like to sit down once in a while.
SCP-5616-1 is another anomaly which will appear when 5616 is uncomfortable and/or in distress, and has been for a period of time ranging from 12 to 18 hours. This being is a ball of white smoke, and is extremely violent. 5616-1 will ‘protect’ 5616 by attacking anything that moves in its range (recorded to be up to 5 meters). Attacks have ranged from surrounding a victim’s head and suffocating, completely engulfing the victim’s weapon and disintegrating it (First recorded engulfed weapon was a FN P90), and to even making humans vanish completely. Conventional firearms do not seem to affect the entity, nor do melee weapons such as short knives. 5616-1's attacks are extremely fast, ranging from .5 to 1 second(s). If 5161 sees an object that will lift it's distress, 5161-1 will disappear.
5616 has shown a large amount of knowledge on anomalies contained by the SCP Foundation, as well as multiple that are not. This knowledge poses a substantial threat to the Foundation, which is one of the main reasons of it's containment, the other being 5616-1.
SCP-5616 does not seem to dislike its containment. When asked, it said it was nicer than the area it used to live in, but also said it would prefer it’s old containment chamber that the ‘Broken Shard Security’ had given it.
5616 seems to enjoy putting bread inside of it’s head slots, and toasting it. It also enjoys giving the toast to people, and anyone eating it has reported that it was perfectly toasted. Testing on the bread shows nothing unusual in its composition.
SCP-5616 was found in an abandoned apartment flat in Kolkata, West Bengal, India. Personnel were sent after rumors of a ‘metal man with a box on his head’ were circulated around the city, including rumors of 5616-1 and odd deaths. Upon discovery, 5616 was extremely cooperative, and tried its best to explain the 5616-1 anomaly and warn the operatives about it. It's story was not believed until the first manifestation of 5616-1.
SCP-5616-2 is a document made out of a material similar to paper, but extremely sturdy and flexible. It was found attached to 5616 with some sort of adhesive upon discovery. The following text is written on the document, and the document seems to be updated by unknown means.
5616 is currently contained at Containment Site 177.
Incident 5616-1: On 21-05-2017, 5616 began pacing its cell and glancing at the metal bench that had been given to him. Surveillance records show that they did not toast a single slice of bread that day. At 0521, the first manifestation of 5616-1 was observed. It appeared directly after a request for a wooden bench. 12 security personnel were lost before a wooden bench was pushed into the room, and 3 additional personnel were 'vanished' by 5616-1. Upon 5616 turning the ‘eyes’ of it’s head towards the bench, 5616-1 disappeared. During this incident, 5616-1 did not chase personnel when they left the room, leading us to believe it is a defensive measure, not an offensive measure. After the event, Researcher Chaudhuri questioned 5616 about the discomfort. 5616 said that it was continuously getting stuck to the bench, like a magnet, which means that 5616 is built out of some sort of magnetic material. It offered apologies for the manifestation of 5616-1, and said it could not control it. Containment Procedures have since been revised.
NOTES:
We should consider moving 5616’s class to Keter, considering 5616 may ask for something we cannot provide. And, is anyone even remotely worried about what the document says? How does this 'Broken Shard Security' know so much? - Researcher Chaudhuri
