Ivan had only a second's thought before four things very rapidly occurred.
First, the girl unleashed a shriek that Ivan was sure was heard by every living bastard back in the facility.
Second, a huge explosion rocked the earth, the sound of it easily overpowering the girl's screech.
Third, he saw, out of the corner of his eyes, a bloodhound strike at the girl.
And fourth, a huge bloodhound advancing on Ivan himself.
His eyes narrowed on the beast as it stepped forth. "Give me your best shot, you oversized poodle!" he snarled at the hound, which was only too happy to comply when a moment later it threw its vast bulk at him, aiming to latch onto Ivan and then clamp its jaws over his throat. As it leapt forward, however, Ivan charged forward as well, the two massive creatures colliding, sending both reeling back. Ivan staggered a bit, but before he could follow up on his attack, the hound was back on its feet and on the offensive. The hell is up with this bastard? the man thought furiously as the hound prepared to strike again. It looks more like a damn wolf than those other hounds.
He wasted no further time on such thoughts, however. As the beast prepared to launch itself forward again, Ivan aimed a heavy blow to its head; it dodged under his arcing attack, and managed to rake its claws down his chest, bringing a roar of pain and rage out of the man. The feeling of the claws digging into his flesh, stopping at the reinforced muscle and bone, caused Ivan's entire focus to turn back to the utter destruction of his opponent. He grabbed the beast's lower arm as it reached forward to repeat its success, his other hand latching onto its upper arm, and with a twist of both hands the beast's arm was snapped at the elbow. It howled in pain, gnashing its jaws, and forced Ivan backwards, throwing him off of it before leaping at him again, bowling the man over onto the ground with the hound on top of him.
One of Ivan's hands latched onto the rabid humanoid wolf's throat, barely preventing it from securing its jaws over his face, while his other hand reached out to grab its good arm and ensure it could not use that to attack him. The two struggled against one another in a deadly stalemate that was not broken even after the beast freed its arm from Ivan's grasp and slashed its claws down the side of his face, both snarling like enraged animals. Finally, however, the hound was unable to fight any further against Ivan's fingers tightened like death around its throat, and after a few seconds its movements became frantic, thrashing uncontrollably; the hound was aware it was in the throes of death, and Ivan knew it as well, applying more pressure as the beast struggled less and less. At last, it began to cease its thrashing, and after a moment, it was still, what little light it had in its eyes disappearing. Ivan pushed the dead body off of him, standing up, his breaths coming in rasps. Blood was running down his face and stained his shirt.
"Ivan!" he heard someone call out his name, and, turning, saw the girl backing against a tree. "We need to go! Now! Gun people are coming!"
Gun people. They'll have those bullets...the ones that can take me down for sure. To hell with that. I ain't getting taken down by some asshole human. He turned, motioning with his head for the girl to follow. Gotta get out of here quick. Before they get their sights on me. Or I'll be screwed.
