My Name is Jack the second, I am a very mysterious man, I have a lot of deep secrets about my knowledge and the stuff I know, I do not share secrets, I know a ton about SCPS, and I've made a lot of friends in research and not even they know what my motives are. I've been working in the foundation for 20 years now. I feel it is time to become an agent.
I am going to bring A senior technician with me, 5 MTF Epsilon 11 "Nine tailed fox" Rangers. This anomaly is a dark shadow, it looks like a black cloud, it avoids the light at all costs, and it can seem to teleport only a few meters, and it swallows organisms into its shadow, the people swallowed by this shadow are deemed MIA or KIA, they are irretrievable. This is SCP 017, the shadow man. My plan is to get a bunch of high powered flashlights and weaken SCP 017, once he is weekend and has no place to escape because he is unable to teleport in the light, I am going to get an MTF to place a box purely filled with high powered light bulbs around SCP 017, to capture him. Once I capture him I am going to keep him in the box till further notice.
I am going to convince the CI that I will unleash the SCP on them killing them instantly, if they don't back down I will either A bargain them with money or B order the MTF to attack the CI. after I get them to back off, I make sure the E11 are extra cautious when heading towards the gate.
Once SCP 017 is safe and secured in the box temporarily, I am going to begin designing its containment chamber at Site 05. My design is going to keep the anomaly in a room solely made out of light, it is 5 feet wide and 10 feet long, It is going to be running on high powered generator along with 2 other backup generators.
