Psylocke (Elizabeth "Betsy" Braddock, sometimes spelled as Elisabeth) is a fictional character depicted in comic books published by Marvel Comics, most notably those comics featuring the superhero team the X-Men.
She was initially a supporting character in the adventures of her fraternal twin brother, Captain Britain, briefly substituting for him in the role.Later, she became the mutant superheroine Psylocke. Originally presented as a telepath, the character was eventually written as unexplainedly possessing telekinesis. Psylocke later possesses both abilities.
Psylocke originally possessed the power of telepathy, she could read and project thoughts over long distances; control minds; subdue and tap into other's powers; affect people's memories; project mental illusions; project psychic waves (psywaves); and generate psi-bolts that could stun, injure, or kill others. She could also project her astral self, and the astral bodies of other people, into the astral plane. She could scan entire towns with her mind, and leaf through the psyches of the inhabitants of a city to learn of their condition or intentions. She could also probe individuals to check up on their status.
When using her powers, a butterfly-shaped energy aura would appear around her face. It was never truly made clear in the comic books by the writers whether this was something that could be perceived by others or if this was simply an 'effect' to show when Psylocke was using her powers to the reading audience (although it was implied that it could be). This 'butterfly' (sometimes depicted as having eyes in its wings) was also the form Psylocke usually took when manifesting her astral form, both on the astral plane, and in the physical world; although she occasionally used an illusory image of her physical body. After her transformation, Psylocke's psi-form changed to reflect her new Asian appearance.
Psylocke has been classified as a master martial artist, though the specific fighting arts she has mastered have never been revealed. Psylocke's fighting skills and techniques have been shown to surpass those of the average Hand ninja, or Crimson Dawn Undercloak, and have been said to rival those of a ninja master.
