SCP-5916-7 attacking a cargo airliner
Special Containment Procedures: An exclusion zone of 1002km shall be maintained around SCP-5916's own 56.52km "zone". All flights, cruises, and vessels carrying professional boxers must be diverted away from or around the 1002km exclusion zones. Instances of SCP-5916 are to be tracked via tag transmitters, and recaptured if the transmitter becomes faulty or non responsive. All incidents must be investigated by Mobile Task Force Gamma-6 ("Deep Feeders"), coordinating with MTF Gamma-5 ("Red Herrings") on repression of any information relating to SCP-5916 incidents.
Description: SCP-5916 is the designation of six (formerly ten) great white sharks (Carcharodon carcharias) that inhabit the world's oceans. They generally appear to be ordinary members of the species, however, all known instances of SCP-5916 are identifiable by a large, dark patch of bruising around one of their eyes (a 'black eye'), and several missing teeth that they are evidently unable to regrow. Behaviorally, instances of SCP-5916 show no anomalous properties other than an apparent inability to stray outside a region precisely 56.52km in diameter.

SCP-5916's properties trigger when a professional boxer (defined as someone who has been paid to participate in a boxing match) enters the region.
Three minutes after a boxer has entered its region of the ocean, SCP-5916 will become hostile and immediately accelerate towards the intruder at speeds in excess of Mach 20. Roughly twenty seconds before acceleration, SCP-5916's attack is preceded by a disembodied sound of a boxing bell ringing three times, which by means of observing past victims of SCP-5916 and testimonies of D-Class personnel before their deaths by SCP-5916, only the target can hear.
SCP-5916's target is typically obliterated upon impact, along with whatever transport they were using. All instances of SCP-5916 suffer no ill effects from the stresses and extreme heat of such speeds, instantly decelerate when their target is dead, and in cases of attacking aircraft, seem to receive no damage from falling back into the sea.
SCP-5916 came to the Foundation's attention in 19██ off the coast of Central Africa after Flight ██████ of █████████ Arline's vanishing coincided with an oceanic sonic boom directly under its last known location. A pattern for its attack "criteria" was formulated after the appearance of other SCP-5916 instances, leading to current containment protocols.

Experiment Log for SCP-5916

Project Head: Dr. Charles Yung
What instances of SCP-5916 consider a 'boxer' occasionally causes it to attack unexpected targets. By observation, the current theory for its attack criteria is as follows: Any boxer (defined below) is considered a valid 'opponent' for SCP-5916. Defined more clearly:
1.) A boxer is any person, human or otherwise, or any animate object that has been paid money, physical good, services, or other compensation for participating in a boxing match.
2.) A boxing match appears to be defined as a refereed, regulated fistfight, or a regulated brawl in general. A person who has simply fought another person does not appear to fulfill the criteria for attack by SCP-5916.
Experiments will be carried out to refine the attack critera for SCP-5916 at Research Head Dr. Yung's discretion. A selection of tests follows.
Date: ██/██/████
Test Subject: SCP-5916-1
Procedure: Two crash-test dummies were gathered at Site ██, and given a mock fight in an improvised fighting ring. Various D-Class personnel were provided to act as the 'audience', with another dummy acting as the 'referee'. After the fight, both dummies were given 500 USD and remotely towed out to the area of SCP-5916-1
Results: SCP-5916-1 does not attack. No observed change in behavior.
Notes: "Given the inanimate nature of the dummies during the fight, it's plausible that SCP-5916 does not consider them actual boxers." - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-1
Procedure: Repeating the previous test, though with the dummy referee exchanged with a D-Class, and instructed to treat the inanimate dummies as though they were actually fighting. As in the previous test, both dummies are given 500 USD and towed out into SCP-5916-1's zone of attack.
Results: SCP-5916-1 charges both crash test dummies, obliterating them upon impact.
Notes: "Previous notes discarded; SCP-5916's definition of a 'boxer' seems rather loose, but the definition of a 'referee' seems stricter. Further testing required." - Dr Yung
Date: ██/██/████
Test Subject: SCP-5916-1
Procedure: Two dummies, refereed by a D-Class, "paid" in one American cent each.
Results: SCP-5916-1 charges both crash test dummies, obliterating them upon impact.
Notes: "The amount does not seem to matter, only the substance. It's reasonable to infer that any accepted legal tender will be considered 'payment'." - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-1
Procedure: Two dummies, refereed by a D-Class, "paid" in one-hundred Confederate States dollars.
Results: SCP-5916-1 charges both crash test dummies, obliterating them upon impact.
Notes: "Currency of the defunct CSA, while not accepted legal tender, could be considered valuable as a historical artifact, and therefore considered 'payment'." - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: Same as previous test, but dummies hauled into SCP-5916-2's zone of attack instead of SCP-5916-1.
Results: SCP-5916-2 charges both crash test dummies, obliterating them upon impact.
Notes: "If possible, I'd like to get authorization from O5-█ to test on several SCP-5916 instances concurrently, to see if any of them vary in their attack criteria." - Dr. Yung
Addendum: Request by O5-█ denied.
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: Two coconut crabs (Birgus latro), refereed by a D-Class, made to "fight" in a mock boxing match.
Results: SCP-5916-2 does not attack. No observed change in behavior.
Notes: "That's about right." - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: Same procedure as the previous experiment, with both crabs receiving one coconut each at the end of the "match".
Results: SCP-5916-2 charges both crabs, obliterating them upon impact.
Notes: "Exhibition matches don't count, apparently." - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: Two coconut crabs refereed by a D-Class, made to "fight" in two mock boxing match. First match both subjects receive a coconut as payment, second match receives no compensation.
Results: SCP-5916-2 charges both crabs, obliterating them upon impact.
Notes: "Once you're considered a "boxer" by the shark, it doesn't seem you can 'undo' that status." - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: One coconut crab and one crash-test dummy are made to "fight" in a mock boxing match. Audience removed, leaving only the D-Class referee. Both subjects "paid" upon the conclusion of the match.
Results: SCP-5916-2 charges both subjects, obliterating them upon impact.
Notes: "It's safe to assume the audience is irrelevant to the equation. Best to leave them out from here on; God knows those D-Class are needed elsewhere." - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: Two crash-test dummies, equipped with modern firearms, refereed by a D-Class, and paid 500 USD after the match.
Results: SCP-5916-2 does not attack. No observed change in behavior.
Notes: "I guess guns are unsporting." - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: Two crash-test dummies, equipped with modern firearms and boxing gloves on their hands, refereed by a D-Class, and paid 500 USD after the match.
Results: SCP-5916-2 charges both subjects, obliterating them upon impact.
Notes: "Really." - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: Two cardboard cutouts of characters from the popular boxing video game █████ '16 is towed out into SCP-5916-2's attack zone.
Results: SCP-5916-2 does not attack. No observed change in behavior.
Notes: "Simple depictions of a boxer don't appear to be enough to set them off." - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: A copy of the video game █████ '16 is towed out into SCP-5916-2's attack zone.
Results: SCP-5916-2 charges the game disc, obliterating it upon impact.
Notes: //"Based on the last test, maybe it doesn't consider pictures of the characters to be boxers, but the data inside the game as counting? The game does have virtual currency in its Career Mode, so it's not outlandish to suggest that counts.
This also explains several incidents where a boxer could not be identified among the crew."// - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: A VHS recording of the 19██ boxing match of █████████ vs. █████████ is towed out to SCP-5916-2's attack zone.
Results: SCP-5916-2 does not attack. No observed change in behavior.
Notes: "Recordings aren't enough. Maybe it considers the fact that the characters in the video game are actively controlled?" - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: A copy of the fantasy fighting game ███████ ███████ is towed out to SCP-5916-2's attack zone.
Results: SCP-5916-2 charges the game disc, obliterating it upon impact.
Notes: "I would hardly call the fighting in this game "refereed" in any sense. Maybe the game's physics engine counts as that?" - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-2
Procedure: A modified copy of the fantasy fighting game ███████ ███████ is towed out to SCP-5916-2's attack zone.
Results: SCP-5916-2 charges the game disc, obliterating it upon impact.
Notes: "Doesn't matter if it's a crooked fight." - Dr. Yung
Date: ██/██/████
Test Subject: SCP-5916-10
Procedure: Two D-Class personnel, both with previous histories of professional boxing, are paid 1000 USD each to participate in a boxing match refereed by Dr. ██████. Upon its conclusion, they are relocated to SCP-5916-10's area of the ocean.
Results: SCP-5916-10 does not attack, but does swim up to the surface and converses with both D-Class personnel. Excerpt from encounter follows:
D-9221: Holy shit.
5916-10: Yeah, yeah I know. Not every day you meet a legend.
D-502: Are you fucking talking?
5916-10: Well I ain't jabbin'. Speaking of which, I'm guessing those poindexters sent you over here, huh? Wanted to see if I'd pick a fight because of you two goin' at it?
D-9221: …Uh. I mean, they paid us to have a boxing match.
5916-10: Yeah, yeah, I know. It's why I came up here. Wanted to give you a few pointers.
D-502 …"Pointers?"
5916-10: Yeah, you know. Right now you're garbage. But you got potential, both of you. I like that. So, few pointers, if you don't mind an old fogey yappin' at you.
5916-10: [Addressing D-502] You, beardy. You got a mean left hook, but you gotta work on that form. You a boxer or a palm tree getting its ass kicked in a hurricane out there? Stop swaying around so much and just throw a punch. And for God's sake, are you blind out of your left eye? Block for once, man.
5916-10: [Addressing D-9221] And you. You got a damn good uppercut, but that's not gonna do you a lot of good when you're as slow as my grandma. You gotta speed up, or you're never gotta catch anyone out there. You wouldn't last two seconds against the guppies I have to deal with out here!
5916-10: …How-
5916-10: Eh, I've wasted enough of your time as it is. Just think about it. And if you catch me out here again, I might be in the mood to show you some real fighting. Just don't expect me to go easy on you! [Laughs]
[SCP-5916-10 dives under the water and leaves]
D-502: I think I liked prison more.
Both D-Class administered Class-A amnestics and released back into general pool of D-Class personnel.
Notes: "Well, that was enlightening." - Dr. Yung
