In honor of #sharkweek Green Ronin has released a villain in their Rogues Gallery line. Here's the description from the product page:
Dr. Connor Kirkstrom is a brilliant man, but knows a savage, remorseless killer dwells inside him. Megalodon the Man-Shark, his bloodthirsty Mr. Hyde, is perversely proud of his place at the top of the world’s food chain, considering all other creatures beneath him. Only other sharks are potential peers, and even they must bow to his superior will.
In addition to the PL 12 villain, the pdf also contains PL 5 minion stats for cyber-sharks.
