Johnston Dewar is a college student in an unknown university who joined the subversive organization known as the Laniakea. He carries a special sprayer disguised as a stinky fish that pelts out stinky, noxious gases.
His Above and Beyond counterpart is Joanna Dewar.
At some point in 2018, Johnston Dewar enrolled in Philippine Science High School's Main Campus.
Johnston was seen trying to repair his friendship with Atlas, getting help from two people that would later head an organization known as the Laniakea. He even offers the Sodalites and Rhodinites a rented area in the apartment he lives in as a space for their review sessions.
Much later, he was recruited to the team and given a fish-shaped stink sprayer. As a member of Sachikayla and Tyriann's team, he sometimes accompanied them in training and recruiting other people like Caspian and Sinclair.
Johnston 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
Johnston is caring, generous, and protective of his peers. 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.
