As an alternate of Dazzler she presumably with the same mutant abilities to manipulate sound into light to a variety of effects. Additionally she wielded Lightbringer, an enchanted uru hammer only lifted by those who were worthy. The hammer allowed her to fly and control the weather (summon wind and lightning) and returned to her grasp when called. The hammer may have allowed her to also create portals to other dimensions like other uru hammers but this ability was not shown.Her power signature was pink.
This version of Dazzler belonged to the Thor Corps of Battleworld who served as a police force for God Emperor Doom. When battleworld was unmade and the multiverse restored, Dazzler-Thor fell through the cracks and ended up on Earth-616. After her death, her hammer Lightbringr remained in the possession of her counterpart who had shown the ability to wield it.
