Gets stronger with rage

The zombies whipped out bows and spears and clubs, or else tore at Sue with their bare hands. It wasn't pretty. Arrows streaked through the air with unnatural speed, and when they struck the Tyrannosaur's hide they sounded almost like gunshots. One zombie rammed a spear cleanly through the massive muscle of Sue's right thigh. A swinging club shattered several of her teeth, and even as I watched, an unarmed zombie leapt up onto her flank, got a hold of the heavy extension cord that held the saddles in place, then drove his fist into her flesh up to the elbow, and started raking out gobbets of tissue by the handful.
I brought up the sparkling blue cloud of my shield bracelet in time to intercept an arrow, and others smashed against it with the force of bullets even as I held it in place. Without being told, I felt Ramirez turn to our right, his own left hand extended, and a concave disk of green light expanded weblike from his outstretched fingertips, covering that flank from still more of them.
But as vicious and as strong and as swift and deadly as the zombies were, they couldn't hold a candle to Sue.
The injuries that might have terrified a living beast only infuriated her, and as that rage swelled, her own grey-and-black hide gained a silvery sheen of power. She roared so loudly that my chest and belly shook and my ears screamed with pain. She caught one zombie in her jaws and flung it away. It sailed up over the nearest five-story building and out of sight in the darkness and rain. When she stomped down with her foot, she shattered the concrete of a walkway and drove a footprint more than a foot deep into the earth around it. The zombie assault turned into one enormous exercise in suicidal tactics, for whenever one of the undead warriors managed to get through to harm Sue, the Tyrannosaur not only crushed the unlife out of them, but grew that much more angry and powerful and unstoppable.
It was like riding a carnivorous earthquake.
"Look!" Ramirez screamed. "Look there!"
I followed his nod and spotted Grevane in the circle in his trench coat and fedora. The necromancer was keeping a steady beat on a drum hung from his belt, and he gripped a staff of gnarled, twisted black wood with the other. He stared at us, his face twisted in hatred, and his eyes glittered with insane malice.
I willed Sue to head for the circle, but the Tyrannosaur's will was suddenly no longer pliable or easily led. The blood rage and fury of battle had overloaded what little mind she actually possessed, and now she was nothing but several rampaging tons of killing machine.
"Hurry!" Ramirez shouted.
"She's not listening!" I told him. I applied my will even more forcefully, but it was like one man struggling to hold back a bulldozer. I gritted my teeth, desperately trying to figure a way to get Sue where I wanted her, and hit on one idea. Instead of trying to stop her battle rage, I encouraged it, and then I pointed her at the zombies nearer to the circle.
Sue responded with bloodlust and glee, swerving to charge toward the zombies nearest the circle, crushing and rekilling them as she went.
