Braddock might be most familiar to fans as one of the most powerful members of the X-Men, Psylocke. However, she has also taken on the role of Captain Britain to lead Excalibur in defense of mutantkind and protection of the larger omniverse. Betsy Braddock also spent some time merged with the assassin known as Kwannon, which further increased her closet of costumed identities.
Betsy Braddock first took on the identity of Psylocke when she joined the X-Men. However, she was still in her original body at the time. She initially wore a strong suit of armor Wolverine had made for her. After she walked through the Siege Perilous and swapped bodies with Kwannon, she stuck to her more familiar ninja outfit.
She eventually was able to recreate her original body, while Kwannon returned to her body as well. They both shared the psionic powers of Betsy Braddock, though Kwannon kept the Psylocke identity for herself. Betsy soon evolved into her new role as Captain Britain while Kwannon led the Fallen Angels and became one of Krakoa’s Great Captains.
