Chess' personality is pretty simple, she's very friendly and cheerful. She also shows to have a bashful and childish side at times, often leading to her being called 'cute'.
She can stun and blind enemies by using her 'Glowy' powers. Her powers basically look like powers of light, also being the same color as her eyes.
She is immune to explosions. (it's tied to her backstory XD)
Sometimes she acts a little bit clumsy. Sometimes she may also accidentily glow so much that she blinds another hero temporarily.
