Arc was a member of a superhero team called the Protectors, who were the stars of a comic series by Malibu. The comic ran from 1992 to 1994.
Arc was a young and particularly enthusiastic superhero who revelled in use of her powers, battle, and being a superhero in general. Friendly and amicable towards her teammates, Arc seemed to get along best with the Ferret and Aura, the latter of whom stating that she reminded her of her daughter.
Arc later joined the Ex-Mutants alongside fellow Protector Gravestone.
