GN-2/V25/35/118/C Lynn was once Lynn Alers, owner of Alers' Submarine Excursions, a moderately profitable scuba touring company in Honolulu. It was a match made in heaven as far as she was concerned as she made a tidy living doing what she loved. To help manage her household she'd acquired GN-1/42/122/P Sylvia to free up more time for he work and passion. When she was confronted with the prospects of conversion one of the benefits of this new form was that it's requirements for oxygen were minimal and as such she could spend far more time underwater, which more and more she began to see her home. As such she'd contrived a new body plan for herself. She'd already had a device installed which allowed her to spend time underwater indefinitely but her new body was much more adapted to her new habitat of choice. Her face was enlongated into a sharklike muzzle, her antenna were put into a set of speicalized ear like fins. Two more abdominal pectoral fins sprouted from her hips and a dorsal fin came from her back. But most impressively she traded her legs in for a mermaid like tail ending in a jetski like hydrojet engine as well as a ballast tank. She'd adopted her new body shortly before the primary activation and never looked back on her old human figure. When the time came, Lynn along with Sylvia and her former biological sister Vivian patrolled the reefs and sea valleys in search for humans to be taken to a secret underwater conversion chamber where their 'school' grew.
