Trollfriend

Trolfriend is the Trollge-infected form Girlfriend takes. During Boyfriend's mental bout with Legion, Girlfriend was kidnapped and corrupted by Legion. This new being was entirely subservient to Legion, causing Boyfriend to go berserk against the Trollge. While Boyfriend was able to defeat and weaken Trollfriend, he was unable to save her from her new form, causing Legion to incapaciatate Boyfriend for several years. After Boyfriend's eventual defeat to Legion and the death of the latter by Case 000, Boyfriend was given the chance to save her again. Trollface re-created the erased world and send Boyfriend back in time, this time giving him the power needed to fight back against Legion and save Girlfriend. Years later, Girlfriend has mostly recovered from her transformation, but still possesses a lighter hairstyle and different eyes from her time as a Trollge.(your boyfriend)
