Grey the MTF

Grey the MTF is a member of the Mobile Task Force of the SCP Foundation. He is mostly known for keeping watch for Dr. Cubano.

Birth
Nothing is known about Grey the MTF's birth or early life, due to it being classified by the SCP Foundation.

SCP Foundation
Grey the MTF works as a MTF (Mobile Task Force) in the Foundation, meaning he helps watch over Keter-class SCPs contained within the facility(unlike Security class, which only watch over lower-class SCP's and Class-D's). This means he gets more free time, and a higher security clearance than Frogy's.

Grey the MTF is also able to use a better suit, which has many internal improvements meant to deal with Keter-class SCP's, that the Security class don't. He has modified it with extra features to deal with SCP's located in the High Containment Unit, which have proven to be surprisingly effective. The SCP Foundation has taken inspiration from his designs for newer models of suits, and as such, they've become classified.

Grey the MTF uses his free time to benefit the Foundation, usually preferring to supervise the Security class doing tests on Class-D. He prefers to be around people who hold tests for Class Ds, and mostly roams around the facility to protect Area ██.

Guarding Dr. Cubano
Grey the MTF was hired by Dr. Cubano sometime in April to protect the latter's research project on the Despacito Spiders. He kept Foundation personnel and Class-D out of the research area, only letting Mr Despacito, A Normal Class-D, and Dr. Cubano's assistants inside.

After Dr. Cubano's death at the hands of SCP-173, Grey the MTF now protects the Foundation from the CI (Chaos Insurgency).
