Heads Up: I'm working on a proper fanfic and wrote this little excerpt to get my imagination going. Think of it as a sign of things to come.

Starscream struggled to make it into cover before the next fusillade of fire erupted from further down the corridor. He couldn't run, not yet; he looked back at the bodies of those who had tried and made it a scant 20 meters before being laid low by the seemingly impossible weight of fire brought down by the forces of Chaos. When he first heard the name he laughed, especially once we discovered them humans. Sure they were half his height, but all the decepticons had quickly learned to fear them. Risking a glance down the corridor he saw a line of heavily armored warriors advancing towards his position. Projectile impacts near his head alerted him that he needed to get back into cover. He sank down into his position, not knowing how he would be able to escape.

His thoughts were interrupted by a low rumbling. He looked around his position, and realized the fire had stopped. The rumbling got deeper, and louder. As he transformed, the wall beside him was shattered and a heavily armored frame burst through with a roar. Amidst the roaring it spoke words that were too guttural for him to understand. Before he could escape the figure used one of its giant fists to swat him to the ground. He reverted back to robot form and landed on his back. He looked upon his attacker, and saw what looked to be giant puss filled boils atop its frame. Hoping to debilitate it, he fired at the dreadnought only to find it shrug the energon bolts harmlessly. It trodded toward him until one of the boils was struck by a bolt and exploded outward, the contents spill all over the floor and Starscream. He laughed loudly at his small victory, his metal began to slough away in great chunks. Laughter quickly turned to tormented screams as he realized his folly, and over his wailing in agony the chaos dreadnought stomped on his leg, nearly shattering it in two. Shakily he trained his weapon at the beast but before he could fire it grabbed his arm with its oversized fist and squeezed.

Screaming in pain, it was all he could do to remain conscience. With a disabled arm and leg, all but shattered to pieces, escape and attack were impossible. The dreadnought standing above him started to shake and….laugh? He looked on in horror at the thought of what could cause a monster to laugh, until he saw what approached him. Amid the combat and pain he never noticed the armor clad warriors bounding toward him. A roar filled the hall, all but sealing his fate. The revving of chain weapons and crackle of power weapons reached a crescendo. He felt dozens of warriors climb atop him, their weapons digging into him. He could feel his spark giving out, strength fading from his body. The last words he heard were simple, though the meaning was lost to him.

"Blood for the Blood God!"
