Clara is a former Olympic weightlifter and security guard who discovered her unusual ability to grow to gigantic proportions during an accident involving an experimental growth serum. Originally from Detroit, Michigan, Clara was always known for her towering height and impressive strength, even before her powers manifested. In her normal form, Clara stands at an impressive 7 feet tall, with a muscular build that was further enhanced by her powers. She has short, dark brown hair that stands up in a spiky style, and her face is characterized by a strong jawline, broad nose, and piercing green eyes. Her skin is of a fair, natural tone. In her "Colossal" form, Clara expands to towering heights, reaching over 100 feet, with her muscles bulging and her clothes stretching to accommodate her new size. She typically wears a form-fitting, tight blue and white costume that allows for maximum flexibility, with a circular emblem on her chest that resembles a weightlifting disc. Despite her immense strength, Clara remains a humble and dedicated hero, often serving as a literal shield for her team. Her superhero career began when she joined the team of heroes led by Captain America, using her powers to protect the innocent and fight for justice. Clara's heroism and dedication have earned her a place as a respected member of the superhero community, often working alongside other giants like Giant-Man.
