This design makes me consider giving the Thanagarians the ability to transforms their hands into organic metal claws.
Other examples:
Crimson Fox: Removes the pheromone powers. She's nano-enhanced cyborg with enhanced strength, speed, agility, healing, vision, hearing, smell and can extend her arms to greater lengths. And of course, claws.
Acrata: She has the ability to teleport through shadows but I don't want to make her a full on umbrakinetic like Nightshade, Shade or Obsidian. Instead I want to give her more magic abilities based on speed, stealth and precision. Something like the Witcher or the abilities from the Dishonored games that are limited yet still potent when combined with her fighting skills.
Artemis: A sort of "magic knight". She is strong and fast (very fast), fights with two sickles and can use a number of spells such as creating magic daggers and mystical bow.
Sasha Bordeaux: In addition to retaining her OMAC powers, she has limited technopathy via touch and can enhance her hands with energy for striking or blasting. Also night vision and stealth mode.
