James grunted and in his gorilla stance looked down from his great height of 20 feet, giant building-sized arms reaching down to the ground. People had finally noticed him because it was hard not to see a monstrous silverback even if he tried to hide in the trees.
They seemed to him so weak and insignificant for something as huge and strong as him. He grunted again and ROARED so loudly some windows shattered. The medallion had embedded itself onto the thick skin of his palm and he could feel it emanating energy. It seemed to react to James' pleasure of being so huge.
Another pulse shot through his massive body and James felt it react to its energy. He growled loudly and looked down. His massive fists began to grow even more, arms thickening with them. "What is happening?! How much bigger am I going to get!?" he thought. The span of his shoulders became much wider and his back lengthened, doubling and eventually tripling his height. James could barely move his head as his traps all but swallowed his gorilla head. His face itself began to change as well as he kept pumping upward.
It stopped resembling a real gorilla's and took the shape of something more monstrous. His jaw jutted forward and massive ten feet tusks shot upwards from his lower jaw.
"I'm a monster!" he thought and growled and grunted, still growing larger and larger, past the trees. He looked ahead. People were staring at the ape-like monstrosity, horrified by the existence of something so massive and powerful. James raised his gigantic hands and to test their power grabbed trees by the handful, tearing them from the ground like they were flowers. He threw the trees away and roared again. He took the stance of the gorilla, massive chest puffing, mighty face looking ahead at the city.
He looked at the tallest building and felt the impulse to lumber towards it and climb it. He would never tire of being so massive! So powerful!
