Scarface was a Meg that was born from Angel's first litter of pups. He first appeared in Meg: Primal Waters where he was controlled by Michael Maren to stalk Jonas Taylor and his daughter, Danielle through the Caribbean. At the end of the book, Jonas used the device against Michael and Scarface leapt out of the water, dragging his helicopter under the water and killing Michael.
At the beginning of Hell's Aquarium, Scarface is attacked and killed by the liopleurodon. He gets his name from the scars on his face caused by a territorial dispute with his larger and more aggressive older sibling. He is about 58 ft long.
