Lynette Guycott has an artificial right arm called a Bionic Arm. The exact reason for why she had her real right arm replaced is unknown, though a possible explanation might be to increase her drumming abilities. Her bionic arm is extendable, allowing her to attack from a long distance. The arm is also quite powerful: One hit from it was enough knock the highlights out of Knives Chau's hair. Near the end of Volume 3, Lynette loses her bionic arm when she's forced to teleport away in order to escape the wrath of Envy Adams. It is unknown if she gets it replaced.
