Chameleon

“Yeah, I dated one for about 10 months. But then they started to grow bigger and became too... monstrous, especially with those damned eyes of theirs! And when my companion started changing color like crazy, I just left it.”

~ Cthulhu

Chameleons are gargantuan lizards/reptiles/amphibians/grizzly bears/land sharks that make Godzillas and Mothras across the world grovel. They also eat New Yorkers and Mexicans alike. Darpadarpdarp.
