I created this one last X-Jam, although the codename is recent and I tweaked the story slightly...
Codename: Transplant
Real Name: Sasumo Tuweth
Powers: Transplant has the ability to exchange any physical feature he has with whoever he touches.
Equipment: Transplant wears an armored mask to protect his face from harm. Transplant also wears a force-field generator on his left wrist.
Story: Growing up in Tokyo, Japan, Sasumo lived a very normal life, in spite being an unusual individual himself. Growing up an only child to his two parents, his father was a famous surgeon with a good reputation, leaving Sasumo with high standards to live up to. While his parents encouraged him to get into the medical field, Sasumo wanted to be one and only one thing: a mutant. Growing up, he witnessed the X-Men sacrifice themselves to the Adversary and immediately worshipped them. Particularily, he was in love with Psylocke, Dazzler, and Storm. His obsession throughout the years grew and he wanted to be them. He wanted Storm's piercing blue eyes and facial features, Dazzler's golden locks, and Psylocke's body. Unfortunately real life got in the way and Sasumo started medical school, although his obsession became a side project that took form as a shrine in his dormitory closet.
Sasumo succeeded and graduated medical school. He started practicing plastic surgery; unfortunately, Sasumo wasn't very good at it. On the verge of suicide, a light was reignited within him as the Phoenix flew above a heavily damaged Japan just as he was about to jump off the roof of his medical centre. Sasumo fell and awoke in a hospital bed. As the nurse caring for him was taking his temperature, his body tingled. Her eyes were replaced with his, her hands now mangled while his could function again. Sasumo looked in the mirror and discovered he had the nurses eyes and her feminine hands. Crawling out of bed while the nurse was in shock of what happened, Sasumo switched his legs with hers, leaving her unable to walk. Sasumo meanwhile escaped. With the nurse taking on Sasumo's previous injuries, the police believed Sasumo severely beat up the nurse. By then, Sasumo put his powers to use and took on a new identity: Transplant.
Transplant restarted his plastic surgery business, and this time was thriving. People paid millions for him to steal a celebrity's body feature for themselves, whether it be the hot soap actor's abs, or the new debutante's nose. Transplant incorporated both male and female body parts. Transplant could not be tracked as he had a new face every time. To protect himself, Transplant started wearing a mask after a celebrity's face was damaged upon stealing it and acquired technology that protected his body from harm. Transplant soon hired the Morlock, Masque, to deform people on purpose so they would come to him for help. Transplant felt he could retire once he acquired Psylocke's body, Storm's face, and Dazzler's hair and until then would continue rolling in the riches.
*I picture him a villain for either X-Force or X-Factor.
