Grace

From a terrifying fairy tail told by old sailors to scare children Grace became more than that once the sea rose up.The ginormous animal is a one of a kind 100 ft long great white shark (almost the size of an adult blue whale ) with 6 rows of sharp teeth that could easily tear apart any skin and most bigger boats.For something with her size she moves unbelievably fast which just makes her the perfect killing machine .She usually roams close to the bottom of the calm depths where all the light forms and comes through a big hole through a massive cave. Her menu is of mostly whales but if that isn't available she eats whatever smaller animals she finds. Grace is always hungry for more food.She isn't possible to be killed because of the thick layer of skin that is protecting her from ALMOST everything.As far as the data base allows us to tell there is not to be more than one of the ginormous sharks existing at once or at least not in the same place. Grace can be distracted for seconds with both dead and alive things that she counts as food ( aka everything that smells or looks like food ). She is aggressive towards everything that dares to move around her, keep a distance and leave as soon as you get a chance.

Note: Encountering this beast will cause you your life.
