DOOM: Spider Mastermind

UAC Demonic Entity Log: 012- Spider Mastermind 

UAC feared the worst when Hell took over UAC Earth Central Command's installation, it being home to some of the most advanced technology humanity has ever built. Though enforced with an exceptional amount of security, a singular prototype nuclear-powered Arachno-Tank was taken by the demonic forces, to be used for their own will. Placed near one of the Hell Gates on Earth, an entity parasitically attached itself to the gargantuan machine, finding itself a new body. Despite the machine's large frame, its movements are incredibly nimble, and the head is protected in the back by what look like Pipe organs. These organs were reported by the Lone Marine to have been able to beckon other demonic forces to its location. According to some members of the research team, the demonic entity that attached itself to the tank was likely to be Lilith or even Hel, the Queen of the damned of Norse mythology. Though these explanations were seen to be nothing more than conjecture, it was given some credence, considering the other demons bowed to the Spider's every whim, easily controlled by its mere presence. This led the team to dub it the Mastermind of Hell's army, responsible for leading the invasions on Mars' moons and Earth. However large and formidable this monster was, the Marine made mention of another titanic machine-fused beast, said to be even more volatile and aggressive.
