Disclaimer this was way before modern civilization, technology, and Felicity Rosehearts existed. You can scar him but you can’t kill him.
I’m giving credit to @mangacupcake because she has helped me with Polemicists background and to The Prince of Egypt because it’s a Dreamworks movie (the best movie and soundtrack that still slaps)
Polemicists Pisti agapi O grouse tou posidona is Thee Leviathan, he’s an ancient being that has seen civilizations being built and destroyed by each other or themselves.
His older brother is the Behemoth and Polemicists is the Leviathan from the Bible, no mortal or immortal can kill then, only GOD can kill them himself
Been alone most of his life and at one point made friends with the Ashengrotto family and has been the oldest family friend to exist (becomes Azul’s godfather in mordern times)
Joined the Atlanta army cause he wanted to help protect his home with out shedding more blood but will when he has too
What was he like before meeting Felicity, feral and bloodthirsty (she tamed him with love and kindness in the future)
He’s a giant in his 1st Leviathan mer form, and has 2nd one that’s 14ft tall
Bloodthirsty because humans kept hunting him despite the fact that he’s indestructible and powerful
Kill count so high that he can’t even remember
Likes to bother his brother whenever he can
Collects his own shedded scales (he still does that in the future old habits stays)
That is him in the picture from when he was younger, he didn’t have scars back then but after getting long pointy spears thrown at him, and being hunted like a wild animal he had gained them from experience you can scar him but remember that you can’t kill him.
