Steve picked the Godzilla man option, and waited, he didn't have to wait long. His teeth began to lengthen and sharpen, his nails lengthened and sharpened as well. Black scales began to cover the majority of his body, with lighter gray scales on his chest and stomach and groin, Gill slits opened up on either side of his neck. His ears became small holes on either side of his head, while his hair fell out.
Then his hands lost their pinky fingers while his feet became more elephant like, with four clawed toes, a long tail emerged from his ass and his nose and mouth pushed out into a muzzle. Then he became much more muscular, gaining prominent pecs and abs, then several large, jagged maple leaf shaped dorsal spines emerged from his back. Then his height increased to nine feet tall. Then Steve moaned as his dick became much larger, with a pointed tip and his balls retracted into a slit between his legs while he dick became much more lizard-like and became fully hard, his change was complete.
