One day Darky just ate a cracker he found in his pocket, nothing serious, right?
Well... Apparently this was a bad idea. Going to bed he felt great, but the waking part was awful. He didn't know that, but during the night he began... growing. Not just growing, mutating too. His legs and arms stretched, muscles bulging and growing, filling with power he could never dream of, His torso grew to massive proportions, tail fin flattening and transforming into a lizard one. His hands changed too, becoming claws of a dragon and his teeth sharpened further into a carnivorous grin of a monster. Sharp spikes sprouted on his back, tearing the ground beneath him. He gained the power to control thunder itself...
The final touch to the change was his mind. The change was simple and immediate - like an eraser removing a pencil drawing from existence, his mind was gone too, filled with basic instincts and mostly - primal rage. Now towering above the cities, his head high in the skies, the Swamp-zilla roared proudly into the sky and began it's long conquest of the world below. There was no stopping the monster, that had control over water, earth and thunder...

Maybe if you asked him nicely, he could pick you up and shove between his pecs? It's warm there~~
