Koen (Kappa Omicron Epsilon Nu) along with her husband were a pair of their home galaxy's most renowned guardians, and devoted their lives to protecting its citizens, whether celestial or terrestrial. When they had to leave their son, Tao Rho Iota Iota, behind to fight in the war against planet Ferrum, they never returned. However, thanks to the locket they left Trii before they left, they will be there in spirit to teach the young star about his newfound powers!

Koen has the amazing ability to transform her body into a liquid state to either reach inaccessible places or to wipe out her enemies in a tidal wave! Though she is powerful, she is kind and considerate to all creatures unless provoked. She'll also teach Trii how to use his shapeshifting powers as tools to aid himself and others to reach otherwise inaccessible areas too!
