Like Legion founder
Cosmic Boy, Dyrk Magz is a Braalian who possesses power over
magnetism. He is the first candidate to distinguish himself at the tryouts held by the Legion. Although acting leader
Live Wire is reluctant to recruit a replacement for Cosmic Boy, who is stranded in the 20th century, Dyrk's quick thinking and willingness to take action earn him a place in the Legion and the codename Magno. His service in the Legion is short-lived. After successfully deterring several rejected applicants' attempt at re-opening the newly filled membership slots, Magno and the other two new recruits,
Sensor and
Umbra, join the rest of the Legion in battling
Mordru. In the following battle with Mordru, Magno loses his powers for unknown reasons. Dyrk returns home to Braal, but is unable to cope with the loss of his powers. Eventually, Live Wire convinces Dyrk to return to the Legion by offering the newly finished Outpost Allon as a neutral ground that he can stay on. After the
time-lost Legionnaires return from the 20th century, Dyrk joins the Outpost's support staff, handling monitor duty and administration.
Science Police Upon the disbanding of the Legion after the Blight and the loss of Outpost Allon, Dyrk joins the
Science Police, following in the footsteps of his older brother Omar. He is assigned to patrol his home planet Braal and unwittingly becomes involved in an operation of the re-forming Legion when he attempts to arrest Cosmic Boy for
vigilantism, which had been outlawed by the
United Planets. Upon learning that Cosmic Boy had intentionally gotten himself arrested to steal a
faster-than-light ship, Dyrk agrees to cover for him on the condition that he be brought in on everything when circumstances allowed. ==Powers and abilities==
