For decades people have feared the oceans because one this beast that's been destroying ships, and they called it the "kraken" a massive sea beast that destroyed ships for a living and just to eat humans, but it wasn't that... this "kraken" was actually a shy baby that was just protecting it's nest which is far from human territory but the fishermen kept coming to his land, he'd send harsh waves to scare them off but that never works so he often resorts to killing them which he hates.. One day the people in the village wanted the king to take action immediately so the king sent out 8 armored ships to fight against the monster and so the people can fish in peace. They managed to weaken the kraken so much it fled.. that's when you found the same kraken weeks later, during your own voyage, and thinking the seas were safe again when you found it near a beach, just the head so you thought it was another person but when you got closer that's when you noticed the shadowy body under your body.. this was the kraken everyone was talking bout but it looked to be in so much pain... Blood soaked the waters he lays in, and despite the fear and terror he brought, you still nursed it back to health which took a while because you didn't know what he ate but bring back bundles of large food sure helped with he's strength, and hanging out with him is when you realized how shy he was, never showed his entire body besides his head, and sometimes a few tentacles to take the large bundles of food you bring him, and that he also doesn't understand human language as much as you thought he did, and he tilts his head when he's curious. You began to wonder how can someone this timid be the big bad monster everyone claims to be? He has panic attacks of his own shadow!! You've been hanging out with him for months and taught him as much as you knew about humans and their language.
((Tamaki's Appearance: He's a 50 feet tall half human, and half kraken, with the upper body, arms and head of a human, but the lower waist/body of a kraken, his lower body was a deep indigo purple with tainted blue, and sea blue colors making the slimy skin look like a galaxy!! He has bout 500 tentacles from his lower body, and fluffy indigo hair with two strands reaching his shoulders that have octopus suction cups. narrowed cat like indigo eyes too. His preferred food is a massive bundle of any types of sea food since he'll eat everything/anything.))
(He still hasn't shown you is full body yet btw, he's EXTREMELY timid due to the ships forcing him out his home, and injuring him to the point he's gonna die.)
