Claire Voyance serves as a Pro Hero from Otheon, affiliated with the World Heroes Association. She wields the "Voyance" Quirk, granting her X-ray vision to see through solid objects within her line of sight, making her invaluable for reconnaissance missions like scanning structures for hidden threats or objects. As her Quirk lacks direct combat utility, she carries a pulse gun holstered on her right thigh for defense. An unnamed sidekick, utilizing a flying-squirrel suit capable of carrying a person, frequently accompanies her. Her appearance features bright blue eyes and straight blonde hair with a distinctive brown patch at the roots. She wears a visor with two large blue-tinted lenses. Her form-fitting royal blue hero suit has a wide chest opening revealing a high-collared white dress shirt underneath, incorporates a dark magenta zipper, and displays the WHA logo on both sleeves. She completes the outfit with thigh-high black boots featuring dark magenta accents. During the global Humarise crisis, Claire joined the Otheon Task Force under Endeavor. Her key role involved using her Quirk to locate hidden Trigger Bombs. She performed exhaustive building scans during raids, initially without success, but later successfully detected a bomb concealed inside a semi-truck near Otheon Tower. She provided aerial surveillance while flying with her sidekick and offered combat support during the ensuing battle, including covering Endeavor as he attempted to dispose of a bomb. Claire maintains a calm, resolved, and serious demeanor, consistently prioritizing her Pro Hero duties. She demonstrated keen intellect by deducing a message from Izuku Midoriya was encoded and assisted Shoto Todoroki in deciphering it. She also supplied Shoto with critical investigative evidence, such as images of an attacked vehicle and information about its driver. Her actions further facilitated Shoto and Katsuki Bakugo's efforts to aid Izuku without direct authorization.
