Lithium is a supernatural, shapeshifting creature, born from the dark energy of a strange realm. He has dark, psychological powers, with the ability to attack with his mind. However, he does not want this. He has arrived on earth, disguising himself as a regular human. He is a part of a friend group, who are unaware of his true nature. Due to constantly wasting his powers to consistently keep his form looking human, he is pretty unhealthy, which gives him a disheveled appearance.
