Galateo Mendel is a college student in Ateneo who joined the subversive organization known as the Laniakea. He carries a wand capable of firing stingers filled with scorpion venom.
His Above and Beyond counterpart is Galadriel Mendel.
At some point in 2018, Galateo Mendel enrolled in Philippine Science High School's Main Campus.
Galateo was known to have snuck photos of quiz papers multiple times, leading Vikram and Astraeus to suggest recruiting him to the organization that would later be known as the Laniakea. While meeting Sachikayla, he receives a wand from her, and discovers it can spray scorpion venom. He uses it to defend against an "ambush" from Astraeus and Caspian.
Later, Galateo is seen robbing the Chemistry unit with several other members. After dispatching the teachers, he brought them to the clinic as an alibi.
Galateo attends the batch's Graduation Ball after he graduates high school. During the ball, he loses his memory due to the cataclysmic result of Sachikayla and Tyriann's falling out.
To be added
Galateo has had several depressive episodes in his past, leading him to become an impulsive troublemaker and risk-taker. However, he still cares about others' well-being enough to avoid hurting them. He is extremely loyal to the Laniakea primarily due to the L.E.N.S.es affecting his mind, though the incident at the Graduation Ball has changed that momentarily.
