Physically, Yelena is quite short (we are never told how tall, but she is portrayed as a half a head shorter than Spider Jerusalem and a full head shorter than Channon Yarrow), with shoulder-length brunette hair and is usually seen in baggy black t-shirts and suits (primarily to obscure her short stature and modest bust—particularly when compared to Channon). Per Spider's orders, as with Channon, she ingested medication to give her a genetic trait protecting her from cancer, and took up chain smoking.
