Alexander is Salome's masochistically devoted servant, displaying unwavering loyalty and clear infatuation towards her. He willingly endures unpleasantness for her benefit, and Salome accepts his service without reciprocating his feelings, though she is not portrayed as particularly abusive. His role centers on assisting Salome in her battles against the Twin Angels, primarily by operating the giant robots she constructs for combat. Following Salome’s defeat, Alexander follows her into exile at the South Pole. Their dynamic remains unchanged throughout their appearances, with Alexander providing steadfast support regardless of challenges. He exhibits no substantive character evolution or expanded narrative role beyond this focused service alongside Salome.
