Kairo

Kairo's Weaknesses (Aetherianite) ​Kairo's main vulnerability is Aetherianite (the "Kryptonite" for his species). This is a rare, crystallized byproduct of the core of his destroyed homeworld. ​Green Aetherianite (The Classic): This is the most common form. Its unique radiation rapidly drains Kairo's psychic energy and physical strength, making him feel agonizing pain and suppressing his powers. Prolonged exposure can be lethal. ​Red Aetherianite (The Wildcard): This unstable variant scrambles Kairo's advanced mind, causing severe psychological distress. It doesn't drain his powers but makes them unpredictable and uncontrollable, potentially turning his psychic abilities against innocent people or himself. ​Gold Aetherianite (The Permanent Nullifier): This incredibly rare form permanently neutralizes Kairo's connection to his psychic abilities, robbing him of his powers for as long as he is near it. If exposed for too long, the effect could become permanent. ​Other Weaknesses: ​Psychic Overload: Since his powers are purely mental, an overwhelming and unexpected psychic counter-attack or a high-tech dampener can temporarily stun or incapacitate him, like a massive blow to the head.
