A blind priest trusted by both the PLANTs and Earth Alliance, thus allowing him to serve as an occasional envoy between the two. He is also closely aligned to the Junk Guild and a mentor to Prayer Reverie. He runs an orphanage in the Marshall Islands and also, with Lowe Guele's aid, brings the severely injured Kira Yamato to Lacus Clyne after Kira's near fatal battle with Athrun Zala. Shortly after he returned to Earth, Athrun paid a visit. While Malchio updates Athrun about the situation with Orb, a young boy says that someday he will destroy ZAFT and kicks Athrun in the leg. Malchio apologizes to Athrun for the boy's insolence and explains that he lost his parents during the occupation of Carpentaria. Sometime between the Battle of Mendel and the Battle of Boaz, Malchio negotiates a treaty between the Junk Guild and the Three Ships Alliance, allowing the Junk Guild vessel ReHOME (aboard which is none other than Lowe) to act as the tender ship of the Three Ships Alliance. After the war, Kira and Lacus move in with Malchio and all of the orphans under his care. Two years later, Reverend Malchio remains much where he was left off at the end of the first series. When the Second Alliance-PLANT War begins, he plays much the same role as he did before as well.
