Roux is often confident in her own abilities as a pilot and a woman, and is not afraid to use her charm to get her out of some situations or just to get under someone's skin at times, teasing them. These tactics were most notably used on Glemy Toto, who she managed to fool into helping her and survive several attacks that put her life on the line, though this later led to an obsession on Glemy's end. Her patronizing attitude also causes problems between her and her squad-mates, often leading to arguments, especially with Elle and Beecha. She considers them as nothing more then childish kids at first, but forms a strong bond with all of them over the course of the series.

One of her most notable abilities is flirtation and acting, often feigning feelings to enemies and strangers to get what she desires. She also has a relatively high skill level as an MS pilot, and she not only chose the Zeta Gundam, which usually only Kamille Bidan and Judau could pilot, as her machine, but she can also operate the ZZ Gundam.
