Alisa Tager (Cipher)Edit
Cipher 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. This process is called "phasing". This ability is very similar to that of Shadowcat. Cipher emits a bio-electric charge through people she phases through.
Dafydd ap Andras (Damian Tryp)Edit
When visiting the past, Tryp is intangible or incorporeal because the future is still mutable. This intangibility increased his durability and decreases his weight.
Katherine Pryde (Shadowcat)Edit
Shadowcat possesses the ability to pass through solid matter and objects 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 was passing could temporarily merge without interacting and each was unharmed when Shadowcat had finished passing through the object. This process was called "phasing". When Shadowcat was phasing, she was, for all intents and purposes, intangible. Hence, when attacked, she could shift into a "phasing" state so as to allow oncoming projectiles or energy blasts to pass through her harmlessly. Shadowcat passed through objects at the same rate of speed at which she wa smoving before she entered it. Following her serious injuries at the hands of the Marauders during the Mutant Massacre, Shadowcat's phased state became her natural state. She only remains solid by concentrating and reverts to her phased state if that concentration is disrupted.
Omega White Edit
He's able to render himself intangible, thus becoming immune to physical attacks.
Onslaught can phase through solid matter by mentally shifting his molecules around another object as he moves forward.
Pietro Maximoff (Quicksilver) Edit
Quicksilver also can use molecular destabilization to walk through solid objects.
Thomas Shepherd (Speed)Edit
He can also use molecular destabiliation to walk through solid objects.
