Shadowcat possesses the
ability to pass through solid matter by
passing her atoms through the spaces between
the atoms of the object through which she is
moving. In this way she and the object
through which she is passing can temporarily
merge without interacting, and each is
unharmed when Shadowcat has finished passing
through the object. This process is called
"phasing." When Shadowcat is phasing, she is,
for all intents ad purposes, intangible.
Hence, when attacked, she can shift into a
"phasing" state (even if she is not at the
time passing through an object) so as to
allow oncoming projectiles or energy blasts
to pass through her harmlessly. While phasing
Shadowcat is still vulnerable to psionic or
mystical attack. Shadowcat can also walk on
air when in a "phased" state.
