Whiteout has the ability to project a flashing white light from her body. This light hit's her opponents with such brightness that is causes them to go blind for a short period of time. Due to unknown reasons, her power only seems to affect the victims she chooses, it does not affect everyone in a certain range.
She is also able to make her abilities affect those who cannot be blinded in normal circumstances e.g. Psylocke (who at one point had cybernetic eyes, which gave her the ability to adjust to different light intensities.) This maybe because her abilities are psionic in nature.
The intensity and range of her powers are unknown and it is not clear if has a secondary ability which allows her to use the affects of the black lotus flower which gives her the ability to control the will of her opponent.
