Asuka Langley Soryu
O'Malley drew inspiration for Envy from several sources, including the "character" of Metric frontwoman Emily Haines as a performer. O'Malley used images of Haines as references for drawings of Envy in volume 3. He stated that he did not entirely base Envy on Haines. He stated that he does not personally know Haines and is not aware of what her personality is like and so Envy's personality did not originate from Haines. O'Malley stated that the inspiration for her hairstyle is from Asuka Langley Soryu.
