She always had a scar in the shape of a wave on her arm, showing her relation to Poseidon, her father. If the sea had always protected her from harm before, will it protect her now, as she is leaving to go on a dangerous quest?
Marina was found by two mortals on a beach in Australia, who later died in a fire. She grew up in an orphanage, where her life was as normal as it could get, considering the fact that she could hold her breath underwater for 3 hours. She had always wanted a life other than the orphanage, and things are about to change for her.
There is a bomb being made, a bomb to wipe out the whole ocean! The creator lives in the Bahamas, and goes by the name of "Great White". But be warned, the scar on your arm is the only thing that can activate the bomb, so be careful, and don't let him catch you.
Marina is given a quest to save the ocean, and is determind to get started right away!
I will get on my journey right away! Off to the Bahamas I go!
Marina swims all the way to the Bahamas, and fights a lot of monsters to find the "Great White".
Marina killed the Great White and at last the sea would be saved. She then conjured up a tsunami to take the bomb away into the deepest trench in the ocean, where it would slowly rust and decompose in the Marinara trench.
You shall never harm anyone in the sea ever again!
Father, I can breathe underwater! Thank You!
Marina returned to her hometown where she confronted her father, telling him of the Great White and her quest. Her father was so proud that she was given the power to breathe underwater, so she didn't have to live in he nasty orphanage.
For your bravery, I have given your the power to beathe underwater, so you can live in the ocean, free from the nasty orphanage.
Didn't you know, monsters never die!
And so, Marina returned to her home in Australia, where she lived underwater, with an island to occasionally come to the surface. She had a few more quests after that though, but none as tough as the great ocean rescue.
