The Man With The Infinity Gun

O5-1 (ft. 1924 - 2018) was a Spanish scientist who worked for the SCP Foundation during the early 20th century CE. He eventually became O5-1 and the head of the Omega-5 research team, designated to develop The Children to combat the Kingdom of Abaddon.
O5-1 succeeded in this task, before killing Administrator Frederick Williams and breaking off from the Foundation with several other O5 members and their MTFs. This group partnered with the Engineer, helping to form the backbone of the Chaos Insurgency.Entry Page: 001 - djkaktus's Proposal I
== Biography==
===Early life ===
Little to nothing is known of O5-1's earlier life, save for his Spanish origin.O5 Command Dossier O5-1 also apparently had a background in science, as evidenced by his doctorate. By the early 20th Century CE, he joined the SCP Foundation and eventually assumed the position of O5-1. He originated the Thaumiel classification out of the belief that the Foundation was under-utilizing their assets. This sparked one-sided animosity towards the Foundation, with O5-1 planning to revolt.
===Twins of God===
O5-1 was assigned as the lead of the Omega-5 research team, heading Project Twins of God in order to combat the Kingdom of Abaddon, a group of extremely hostile reality benders that conducted raids on various Foundation sites under the guide of God-King Abaddon. O5-2 was originally going to head the project due to his longevity with the organization, but 05-1's charm convinced then-Administrator Frederick Williams otherwise. 
The project began in northern Mexico, using three anomalous items (Subatomic Pumping System (SPS), Harken's Gateway, and Multiple Injections), construction and maintenance materials, and fifty or more Class-D personnel. The site constructed in Mexico was under the guise of a US military waste disposal site.
====Progress====
Soon after moving the newly created Item-001 to San Marco after the original site was rendered inoperable, O5-1 sent a letter on 3 April 1924 to Williams, asking for permission to continue further in the project despite the budget cuts. Williams wrote back 12 days later, telling O5-1 to only utilize the adults from the town, as he did not wish to shed more innocent blood than what was necessary.
O5-1 ignored his orders, utilizing children kidnapped from the San Marcos de la Vida Eterna Church to contain 001. Seven months later, they finally managed to contain 001 within the children, utilizing the SPS to pump the power of Harken's Gateway and the Multiple Injections into them. The resulting power killed many Class-D personnel during the recontainment.
==== Testing====
On 17 January 1926, the first tests utilizing the item were conducted, with O5-1 overseeing them. The tests were highly successful, vaporizing all targets used in the tests. O5-1 commented in the report that the children are highly effective and believed them to serve their purpose when the time came to properly utilize them
Less than a month later, on 2 February, Williams wrote to O5-1 that he was pleased with the results, but also concerned with O5-1's well-being. He wrote back thirteen days later, stating that he was fine and was awaiting Williams' arrival for the demonstration.
===Betrayal===
When Williams arrived to the facility, he watched the demonstration as O5-1 spoke the activation words to the Children. However, instead of only annihilating Abaddon, Williams was destroyed as well. He sprinted to an emergency exit, vacating the premises. O5-1 went on to form one of the earliest incarnations of the Chaos Insurgency, alongside four other Omega-5 members, a number of junior staff members, and half of the senior staff at Site-15 along with quite a few SCPs.
It is unknown what happened to O5-1 after the incident, but it's extremely likely that he died over the past century.
