There's only three Thaumiel Class so far, but I'll see who else I can add.

Thaumiel Class are the most dangerous of all SCPs. Though they may not immediately kill you on sight, they possess incredible godlike power(s).

They'll like it when you pet them, but if you pet them in the wrong spot they'll rip your head off.

SCP-3,000
"X-Event"

Object Class: S̶a̶f̶e̶ Thaumiel

Special Containment Procedures: SCP-3,000[who will be called 3k hereafter] is to be kept in a 20m x 20m x 10m iron cube. The front side; the side facing the hall, is to be made of reinforced hurricane glass. He/it is to be on a constant dose of anesthesia, midazolam, ketamine, ██, and ████ if needed. ████ is mandatory to keep 3k from teleporting and suppresses its/his magic. It is not, however, mandatory to keep 3k in a drunken/delirious state from other medication unless after a breach. After a breach, a 4-billion volt shock roughly three to five minutes long should be delivered to 3k.

3k is not permitted to wear any sort of clothing. Not only is it a skeleton and does not need clothing, but 3k has and will use any item it can hold as a weapon. An example is the death of Dr. ██. Do not give SCP-3,000 tacos under any circumstances. We're looking at you, SCP-963-131.

Any requests to see/come into contact with any other living thing must be accepted by both Dr. Xed and whoever leads the class belonging to who 3k wants to see. If accepted, researchers must take note on how the two[or more] interact. If aggressive, remove and sedate 3k immediately. If passive, further research is mandatory on all categories regarding their relationship in an attempt to find out more about 3k and the SCP he/it is communicating with.

If angered and 3k breaches containment, call a full level 3 lockdown on all wings. All D-Class personnel and guards are required to try and sedate 3k before he/it causes any casualties.

Description: SCP-3,000 is a milk white 'skeleton' roughly 5'6 in height and about 70 pounds. 3k claims that it is male, though it's a skeleton for crying out loud! 3k does not have any organs, mussel, skin, etc., at all. 3k cannot reproduce[as far as the foundation knows]. 3k is guessed to be related to SCP-076.

His/its right pupil is a red oval that varies in size depending on 3k's mood. 3k's left pupil is a white oval that varies in size depending on 3k's mood[ex: tiny when scared; large when content] or the room's lighting[ex: small when bright; large when in the dark].

Though 3k is classified as a skeleton, he is different than the average human skeleton, or any other type of skeleton on Earth, not counting other SCPs. While from the neck down is that of a human's skeleton, the head is more rounded and they have no jawbones[their skulls is completely solid/one piece]. It is impossible to know how 3k, or any other skeleton SCP, can even open their mouth or blink. 3k also has a tail, roughly three inches long.

When angered, SCP-3,000 enters a total rage state. He/it summons multiple knives of different shapes and sizes. The knives often float or hoover above or around 3k. They fire at speeds up to 40 miles[64 kilometers] per hour. SCP-3,000 itself/himself will carry a large knife that resembles one a butcher would use that is roughly the same height as 3k. Both of 3k's pupils change to a red target symbol. It is unknown where these knives come from, though a pocket dimension is possible.

If any sentient living being is cut by one of 3k's knives, they will become limp for a few seconds. Completely collapsed, all vital signs gone. Then the subject will become puppet-like, completely under 3k's control. D-Class personnel describe it as being mostly blind and mute, but able to hear and feel. They say all you see is red and white in no certain pattern or shape.

Often, small purple X's dot the subject's body for an unknown reason. This only occurs when 3k decides to "OVERWRITE" the subject. If the subject is being controlled by 3k, they might be victim to the overwrite process. Why 3k calls it overwrite, we do not know. This lets 3k erase bits and pieces of the subject, making a once energetic person quiet and shy, etc.. He/it can also manipulate memories, and can make people turn on the Foundation even after freed from 3k's grip. There is no known cure, but 3k will turn them back to normal once out of his/its rage state.

Once out of the rage state, 3k shows extreme guilt and accepts any punishment for his/its actions. This proves that 3k is either unaware of when entering a rage state, feels absolutely nothing when doing so, or, based on other notes, some outside force takes control of 3k. For about one day since being sedated after a rage state, SCP-3,000 will remain in a dormant state and is prone to nightmares.

SCP-3,000 is prone to nightmares both before and after breaches and rage states. He/it will often wake up screaming in another language, scared and in an almost traumatized state. This can help prevent breaches. 3k refuses to say what the nightmares are about, even after being either/both physically or mentally harmed/strained.

SCP-3,000 was originally classified as Safe, but was changed to Thaumiel ever since his/its first rage state, which is the worst of the recording rage states. It caused the death/injury of almost all D-Class personnel.

New Note[██/██/██]: 3,000 shows great liking towards SCP-682. We might be able to use this to prevent future breaches.

New Note[██/██/██]: 3k and 682 are very attached to each other. They both are almost always in some sort of physical contact when allowed to see each other, one way or another. If one if severely injured, the other enters a rage state(though 3k seems to have more control over harming others when this happens). This can be either very good or very difficult to work with.

SCP-657
"Death"

Object Class: Thaumiel

Special Containment Procedures: Due to how hard SCP-657 is to contain, the ways of containment have varied. The standard special containment procedures are: Keeping him handcuffed at all times. Make sure that none of his body is shown except for head/face.

657 finds amusement in our attempts to capture and secure him. He breaches very often. If found wandering the foundation, just don't try to tick him off. He has a short temper, and being a sadist, doesn't feel much in killing staff. If found, all personnel are to leave the area immediately. All on-site and off-site guards are to attempt to contain SCP-657 immediately.

In total actuality, SCP-657 is just bored and stays in the foundation because we're 'exciting'.

Description: SCP-657 is Death. Yes, the god. He is the physical embodiment of death. He prefers to go by Death or Reaper, depending if he considers you a 'friend' or not. He only considers SCP-048 as a 'friend'.

657 is a male skeleton about six feet tall. When in a 'good' mood, he has white pupils. Other than that, his eye sockets remain empty. When severely angry, his left pupil is a blue circle. He wears a black cloak with black t-shirt and black shorts underneath. It/he can create a scythe from nothing, though it does not know how.

Death is relatively calm, if not lazy. He is curious about 'mortals' and doesn't try to hide it. He has said a few times that he dislikes his natural ability.

His natural ability is that if he comes into any physical contact with any other living thing, it dies. This is true for most SCPs, all staff/personnel, and plant life. He is intrigued by those who don't die by his touch, such as SCP-682, SCP-073, and SCP-048.

Note: Death cannot kill SCP-048, and expresses great interest in him. This includes teleporting into his containment(which scares 048 horribly), watching him sleep, and carrying him wherever he goes.

This had resulted in small alarms when 048 'goes missing' without any trace. SCP-048 acts annoyed by this. Cameras had showed, though, that when alone, he clearly enjoys being with SCP-657.

SCP-343
"Seraphim"

Object Class: Thaumiel

Special Containment Procedures: SCP-343 is to be chained on all limbs, the base of the wings included, to a solid obsidian floor. SCP-343 is to be kept in a 6m x 6m x 6m cubic obsidian room guarded by no less than six(6) elite guards armed with the necessary sedatives to silence 343.

In case of a breach, level 3 lockdown is required. All guards are to be sent out to sedate 343, and all D-Class are to distract them(SCP-343) so the guards have time to sedate 343.

343 is to always to be sedated with [DATA REDACTED], anything to numb comprehension, and anything to halt movements, and the same formula for SCP-3,000 to prevent teleportation. This does NOT mean that 343 must always be in a numb-minded state.

There are periods in time when 343's brain wave(every skeletal SCP shows brain waves, though it is unknown why) change drastically. When this happens, 343 is passive. It is assumed that 343 is safe when showing certain patterns, and hostile when showing others. If SCP-343 keeps the basis of these patterns for more than an hour, he may not be drugged. During this time, 6-8 elite soldiers must keep track of him at all times.

Description: SCP-343 is a skeleton roughly eleven(11) feet tall. 343 prefers to go by Seraph, Seraphim, or Thought and claims to be genderless though is fine with male pronouns. It/he has six(6) wings. His pupils vary in color. Each of the six wings has a single eye, with their color varying.

The lowest pair is completely skeletal, and is plain white with purple tips. The eye on the left wing is purple, and the eye on the right wing is orange. The middle pair of wings is larger than the lower pair, resembles dragon wings, and is teal with the a green bottom/edges. The eye on the left wing is blue, and the eye on the right wing is yellow. The topmost/largest pair of wings is birdlike, with the top being red and fading to orange at the bottom. The left eye is teal, and the right eye is green.

SCP-343 has an animal/crocodile-like skull hovering above his own skull. The skull seems to be sentient, and cannot stray too far from 343.

Compared to other skeletal SCPs, 343 is a god. While most skeletal SCPs have one 'soul', 343 appears to have nine. White, green, orange, blue, teal, purple, and two red. The eyes on its/his wings each resemble a soul.

Before containment, 343 told staff that eight of the nine souls belong to human children ages 10 or 11 to 13 or 14 years of age. He said that he was only a skeleton, but absorbed the seven souls. It is unknown how he got the eighth soul, and refuses to tell us. Before containment, he mentions and hints at there being more or what he calls monsters. After containment, he refuses to go into more detail. It is understood why. All persuasion attempts have failed.
