*The very first SCP creatures made by me and a friend who also loves SCPs. Both of us do martial arts, so we made martial arts inspired SCP creatures. Picture made in Rinmarugames.com*

Item: SCP 4000, also known as The Martial Artists

Object Class: Euclid

Special Containment Procedures: Subjects must be kept together in a 12m x 10m room lined with mats or padding with bare floor, such as stone, wood or other materials, around the perimeter of the padded 'training ground'. Martial arts weapons and training gear such as swords, gloves, punch bags, towels and various other weapons must be kept in the room at all times and replaced when broken. Water/fluids and food must be replaced when empty, though the subjects do not eat often.
All personnel who come into contact with SCPs 4000-1 and 4000-2 must be trained in at least basic hand-to-hand combat.

Description: SPC 4000-1 and SCP 4000-2 appear to be humanoid creatures with ashen skin that display a few bruises and a small number of interspersed bleeding cuts. Both appear to be undead, with blue-ish lips and completely black eyes so it is unclear where they are looking, even if they are face-on with someone. 4000-1 appears to be a heavyset female with broad shoulders and long dark brown hair -just past her shoulders- tied into a plait, whereas her training partner (SCP 4000-2) is more slight/thin and a little taller with the same shade of dark brown hair as his female counterpart, though his is shortish and with a fringe on the forehead, his fingers are slender, both of their fingers are slightly longer than the normal digit length for a human. Both wear frayed and bloodied martial arts uniforms and black belts, minus shoes so they are wearing black socks.

Their personality is cold and strict and seem to radiate authority, though they firstly appear inviting to 'new students', talking mid-technique if they must. Though they are potentially omni-lingual, they typically tend to speak with British accents.

The powers they have exhibited are knowing many, if not all, martial arts techniques known to man as well as reanimating the corpses of their deceased victims, talking to them (though the corpses do not talk back. The bodies appear to listen and respond with body language and are capable of throwing punches and kicks) and using them as opponents, sometimes ganging up on live students with them. Any way of killing SCP 4000-1 and 4000-2 is unknown.

Both SCPs will not kill anyone under the age of [DATA EXPUNGED], reasons are currently unknown.
Harking back to the 'class participation', the SCPs will invite anyone of any age; living, dead, disabled, well, etc. to participate in the class regardless of age or condition. Some have reported a low-key element of mind control or fear induction that draws the 'participants' in and gets them involved in the brawls.
If the person loses against the SCPs, they will die by either turning to dust or by a bladed weapon if one or both 4000-1 and 4000-2 have them to hand. If the person tries to leave, they will endure a heart attack that results in death. However, if a person wins or draws against the SCPs, it/they will become more friendly towards the personnel. They initiate a bow to them (which the personnel must return) before allowing the personnel to socialize with it/them

They usually praise the person on the job well done and say that they look forward "to seeing them next session"

Addendum SCP 4000-A: The following subjects have been tested in the 10m range of participation.

3000 year old Pharaoh corpse: The heavily emaciated mass of bones performed surprisingly well in the lesson, however, during the final spar was beaten to ashes with it's own spine.

Quadriplegic Class D subject: Appeared to gingerly stand up and painfully participated in the lesson

18 month old male: The child wandered cautiously into the dojo and was promptly ignored.
