Astra has the ability to reduce her density in order to become intangible. When immaterial, she can pass through solid objects and vice versa. She has also shown the ability to punch an 'intangible' Shadowcat, showing that she can match her molecular density.

Astra can also use her power offensively by phasing her hand into her opponent and becoming partly solid. This tactic causes a physical shock to Astra's opponent, who is rendered unconscious.
