He spent much of his time crying in a jar, hiding behind his ink sacs. This bullying caused him to be obsessive about his diet and calorie intake now. Obsessed with staying lean and slender. ​The Change: Driven by insecurity, he mastered transformation magic to completely suppress his octopus traits on land, erasing any physical reminder of his childhood. ​Personality ​The Businessman: Azul behaves like a polite, silver-tongued corporate lawyer. He runs the Mostro Lounge through legally binding contracts, exchanging wishes for collateral.

If a situation falls outside his calculations, his polite facade shatters into dramatic, panicked tantrums. ​The Motivation: Beneath his greedy, manipulative exterior, Azul is an overachiever driven by a deep need to prove he is no longer the weak, bullied child from the bottom of the sea. Everything he has, he earned through sheer hard work.
