Hard to destroy human (SCP story)

SCP-682

I woke up to a siren echoing throughout the room, I jumped up and looked around. "SCP-700, remain calm. Everything is under control." I paced around the room for what felt like hours, finally the sirens turned off. The door to my room opened and guards slowly approached me, I let them put me in shackles and drag me out of my room. "Where am I going?" I asked the guards, they ignored me and continued on their path. We went down many floors on the elevator, once we exited I recognized the area immediately. "This is where I ran." I muttered to myself. The guards led me towards a large room, I read a sign labeling it a testing room. The guards put a blindfold over my eyes and replaced the shackles with a thicker metal. I heard a door open in front of me and felt a rifle stab into my back pushing me forward. I slowly moved my feet forward, the door shut behind me loudly. A buzzing went off. "SCP-700 remove yourself blindfold." The object on my hands released and I removed my blindfold. The sight in front of me took my breath away from my lungs. In front of me stood SCP-682, no restraints, no acid keeping him at bay, and no guards to help me. I took a step back, it looked down at me as if it were wondering how to kill me. "Y-You." I said dumbly hoping the large creature recognized me. "We meet again." It's voice made the room shake, it took a step toward me almost making me lose by balance. "You remember me! You remember I fed you!" The word fed made my stomach turn. The creature towered over me, it's intimidating face looked permanently angry. "I remember you killing the guards yes, but you're still a living creature. A nuisance that'll end up dead at some point." My heart dropped, and my anger started to rise. Do this giant crocodile really call me a nuisance? I glared back at SCP-682. "I'm going to survive, and I'm going to get out of here. No matter the cost." The creature studied me, it lowered its head to my level. "I'll let you live, but only this once. After this, if I see you again, I'll kill you." With that the creature turned and walked to the other side of the room where another door was. I looked at the one way mirror, it's obvious to anyone that I was going to die. I glared down at my shoes and clenched my fists. "I'm leaving here, even if it means I kill a worthless creature with a number!" I yelled out, the creature stopped. It turned its head back towards me, the look in its eyes sent shivers down my spine. "If you want to live to tomorrow, I'd bite your tongue." A dart came flying from the wall and hit the neck of the creature, it howled in pain and wobbled on its feet. The vibrations caused me to fall back and hit the back of my head on the ground. I groaned in pain and clutched my head, the creature took one last look at me before it fell over on its side. I stood up and studied the body of SCP-682, I noticed scars covering almost the entire body. Some guards came in and shackled me, the dragged me out of the testing room and began leading me to my cell. What was it's issue, it acted like I had done something to it. I'm hoping I'd never see that creature again.
