She doesn't have the same speech pattern as the other clones, like talking in the third person narrative perspective, but she still refers to herself as "Misaka" or "this Misaka". Her perspective on life began to change when she set herself up to "detonate" since she had no more purpose and Accelerator stopped her from doing that, preventing her from committing suicide after she failed to eliminate him. Though she has the same appearance as Mikoto, her personality is vastly different, even from the other clones. In New Testament, Misaka Worst wears a pink and white aodai given to her by Yoshikawa Kikyou. To prevent this series of clones from being controlled by Last Order, She was cut up and had many metal parts embedded in her, which according to the Misaka Worst that fought Accelerator, was painful beyond belief. She doesn't wear a similar hairpin as the first batch, and does not wear Tokiwadai Middle School's uniform instead, she wears a full-body suit. Her physical features also differ to the first batch of Sisters she has dark circles around her eyes and has orange irises, compared to the gray irises of the 20,000 Misaka Clones and to the Original's brown irises. She has also been noted to have larger breasts compared to the others, a fact that both Last Order and Mikoto are jealous of even when she doesn't mention it. It is also pointed out that she is 2-3 centimeters taller than the original.
