Peridot

Peridot has lime-green skin, pale chartreuse yellow hair styled into a tetrahedron shape, and dark green eyes that are usually tinted by the yellow color of her visor. Peridot's gemstone is located in the center of her forehead.

She can be calculating, paranoid, socially oblivious, and has an inflated ego. However, she is willing to apologize for her behavior. Peridot excels at problem-solving but can be naive, stubborn, and quick-tempered. Peridot is incredibly dedicated and somewhat possessive, occasionally to the point of obsession. Peridot used to be extremely self-absorbed. Many of her childlike behaviors, particularly her temper and arrogance, stemmed from her over-inflated ego. This is not to say Peridot is incapable of putting others above herself; she is just not used to having others who are willing to do the same for her.
