Elevator Pitch: Deadly prehistoric Animalia predatory fungus with alien origins, first discovered at the Chicxulub crater as fossils. SCP-5377 specimens are continent wide, as they travelled into Earth through the Chicxulub impactor and into the Gulf of Mexico. Both parasitic and saprophytic.
Central Narrative: The SCP Foundation finds fossilised specimens of SCP-5377 spores in Site 43, a recently built and naïve site in the Chicxulub Crater, Mexico. Upon human experimentation, SCP-5377 spreads due to a design flaw in the ventilation system and grows through Site 43, leading to 7% of the site to be quarantined and later restored after a swift recontainment from MTF-Chi-7. SCP-5377 is a marine fungus with unstable, virus-like DNA which can't be traced to any other type of microorganism on the planet, using any type of animal in its waters/using its waters with a cerebellum as hosts, such as ancient Caiman. SCP-5377 is also a Saprophytic fungi, as when it is not in a host, it can feed on algae, phytoplankton and animal shells. Has been seized by Chaos Insurgency during a site breach, which has mutated it genetically via CRISPR-Cas9, and has used it in various incidents to attack the foundation. SCP-5377 also has the capability to spread and manifest in humans and can take control of humans using the cerebellum and brain stem which it uses to paralyze the body and then release fungal spores, classified as SCP-5377-1. If more than two specimens are within a 4 meter distance, SCP-5377-1 develop a symbiotic mycorrhizal-like fungal network with themselves. In this event, SCP-5377-1 are able to control spores to use against hosts. Chaos Insurgency's mutated variant has transformed this SCP into a biological weapon, causing various containment breaches and a site destruction. Chaos Insurgency's variant of the fungus has a different variant of SCP-5377-1, Classified as SCP-5377-2. SCP-5377-2 is reanimated and has basic motor function, in which it uses to grab hosts and release fungal spores, producing more SCP-5377-2.
Hook/Attention-Grabber: This is an alien fungi that can take full control of a human, with specimens continent wide, and the Chaos Insurgency has seized a specimen, mutated it and transformed it into an incredibly effective biological weapon.
Additional Notes: This is my first time writing an SCP.
