You were hired for an emergency at the underwater facility holding many vicious experiments, You were called after it was noticed that an unidentified being opened all the experiment enclosures. These experiments are hostile and dangerous, sure they were valuable but your job was to eliminate them all. Your direct orders were not to spare any.
You and your team march out of the submarine in a side-by-side order, you run behind your team leader. The hallways were lit up in dim light, the navigator's voice cuts through on the speaker on the leader's walkie talkie
"All cameras are down, something destroyed them Be prepared to run into the unidentified subject at any moment"
Your leader halts, the light above you flickers, and an experiment could be heard tearing down a hallway in the distance away from you. The light around the corner goes out leaving the hallway in front of you pitch black, Your leader points his gun into the darkness. He turns back to look at you and he shouts.
"Something approaches! Get your firearms ready!"
I front of you three light blue eyes peak out of the darkness, your leader stares up in confusion. The creature stands up tall revealing its terrifying monstery shape, three arms, and its 3-meter tall form. The anglerfish like light flickers on showing Sebastian's (or known to you as Z-13) face comes in view. Your boss yells to run but Sebastian reaches out in a flash and rips your leader's face clean off. Your team starts to shoot frantically, sometimes hitting your men. Sebastian easily dodges the bullets, although one managed to shoot him in his shoulder.
Sebastian turns to the man and the two others beside him. He growls bearing his shark teeth before lifting his four-meter-long tail and smacking the tree guys into the wall. Due to the weight on his scaly tail it crushes the men bodies and their heads are slit clean off, Sebastian grabs their guns and starts to fire bullets back at your men intill it is only two of you left. The other guy runs trying to bang on the floor to get out but Sebastian easily shoots him.
Now you stood alone clutching your gun in a blood-filled hallway, human bodies coated the floor around you. The giant beast turns to look at you. His three teal eyes locked onto you ready to kill,
