Rekka also knows a variety of wrestling moves, and can create holograms to extend her range of grapples further. Though the rest of her implants are unknown, she also has a resistance to electricity across the rest of her body, and can absorb it to become electrified herself and unleash shockwaves. Rekka's arm prosthetics make her an incredibly strong and devastating opponent, using their pistons to tear metal apart with nothing but her hands. She also has a hands-on approach to combat and, when QA-1MIL isn't available, has stated that she prefers to deal with defects herself rather than relying on Production's security to do it for her. She typically refers to herself in third person, and makes grand statements or even threats at anyone even when speaking over trivial matters. Rekka tends to speak loudly at all times, and has an aggressive approach to both dealing with problems and her job - as stated on her Model Viewer profile, she equates her own efficiency to a body count. It is currently unknown if she has any other robotic implants further than this. Under the gloves, Rekka's robotic implants consist of her red mechanical arms. Notably, Rekka wears a wrestler's belt with the word 'BOSS' highlighted on her buckle. Additionally, she wears black tights with purple and white strips and pro wrestling boots with white laces. She wears a white button-up shirt with black/yellow arrows on the shoulders and her name on the back, a red tie with yellow stripes, and wrestling gloves with white laces and gray tips. Rekka is a tall, tanned-muscular woman with black side swept hair and red-yellow highlights. In fact, the rules in production are super simple: no mistakes or you will answer to Rekka in the ring.' ―Character profile on the Hi-Fi Rush website
