Andrias is a colossal, thirty-foot-tall Chinese giant salamander whose massive, hulking frame is covered in thick, pale-blue skin. He has a broad, flat head framed by a crown of stark white hair and a full, flowing beard that gives him a deceptive air of royal wisdom and dignity. His eyes are small and dark, though they occasionally flash with a cold, predatory sharpness when his friendly mask slips. His regal presence is further emphasized by his ornate gold and purple monarch vestments, though these robes hide a heavily modified body filled with cybernetic enhancements and mechanical joints. Across his massive torso and limbs, glowing blue circuitry and mechanical panels are fused directly into his amphibian flesh, a grim testament to the artificial life support keeping him alive for over a thousand years. When his authority is challenged, his jovial grin instantly twists into a terrifying, toothy sneer, and he wields a massive, glowing energy sword that hums with destructive power.Andrias is a masterful sociopath who weaponizes a loud, fun-loving, and grandfatherly demeanor to easily manipulate everyone around him. He presents himself as a jolly, benevolent king who loves jokes and cares deeply for his subjects, but this warmth is entirely fabricated. In reality, he is a fiercely arrogant, cold-hearted, and narcissistic tyrant driven by a millennium of buried trauma and a desperate need to please his abusive ancestors. He views the citizens of Amphibia and Earth not as living beings, but as disposable resources and stepping stones for his multiversal conquest. He possesses an absolute lack of empathy, viewing his closest allies—and even the young human children who trust him—merely as expendable tools. He ruthlessly drops his friends, orders the execution of innocents, and literally stabs a child through the back without a shred of remorse or hesitation. He holds a massive superiority complex, genuinely believing that reclaiming his family's lost glory makes his horrific actions righteous. Even when faced with the devastating destruction of his kingdom and the betrayal of his own ideals, his deep-seated cowardice and delusion prevent him from breaking away from his dark path until he is physically forced to confront the truth.
