A rather gruff woman, Madame Christmas is the proprietor of a hostess bar in Central City frequently patronaged by Colonel Roy Mustang. At first, it would merely seem that this bar is further proof of Mustang's unapologetic debauchery, but it becomes quite apparent that the women under Madame Christmas' care act as secret informants to Mustang and his squad and that Madame Christmas herself is a skilled intelligencer and contact between Roy and Lt. General Grumman in East City. It has been recently revealed, by a secret investigation into Roy's past carried out by Central Command's agents, that Madame Christmas' real name is Chris Mustang and that she is Roy's foster mother. In Character Guidebook 3 released recently in Japan it's revealed Chris Mustang is actually the younger sister to Roy's biological father, making her his aunt. According to this guide, she took Roy in after the death of both his parents, when Roy was still very young. - fma.wikia.com
Leo's younger brother. He carries a locket of his mother with him, even though it was broken and would not open. He was captured briefly by mercenaries in Central, but was rescued by Scar, Alphonse, and Edward. Rick was nearly killed during the rescue attempt, only the locket of his mother saved him. The force placed on the locket caused it to open, revealing a picture of Rick, Leo, and their mother; additionally, several small pills for the treatment of blindness were discovered inside it. Toward the end of the anime series Edward receives permission from the military to have Rick and his older brother Leo released and transferred to Resembool; however both Rick and Leo turn down the offer. In the manga, Rick and the old man pull Scar out of the sewer in East City after Scar's first encounter with the Homunculi. They tend to his wounds until the mercenaries try to arrest Scar, then Scar leaves the slum and they are not seen again. It is implied that the fair-skinned and fair-haired manga version of this boy is half-Ishvalan (as he reassures an injured Scar that he's safe because "Mom and I are Ishvalan too!") Rick wasn't named in the manga.
Bido was a chimera created in the Fifth Laboratory; after escaping it, he followed the homunculus Greed. Before his transmutation, he was a member of Martel's military special ops team which instigated the Ishval revolt. He was fused with a lizard or a gecko; this enabled him to have a firm grip on surfaces when climbing, and to use his tail as a bludgeoning weapon. He is bald and speaks in a raspy, hacksaw voice, though it's unclear whether this is a result of the fusion or not. In the first anime, he is killed by the military. In Brotherhood, he survives instead. He searches for Greed and finds him in Father's lair. Unfortunately, the homunculus has forgotten about Bido and kills him. Afterwords, Greed's old memories start to return and Greed realizes he has killed the last member of his family with his own hands.
Scar's mentor from Ishval, a holy man. The two got separated when Kimblee attacked the group of refugees of which they were a part. Upon learning of his student's "crusade" against State Alchemists, he counsels him on the teachings of Ishvala. In the anime, he says, "Even in the darkest of suffering, a man can sleep. But for the man who inflicts the suffering, his mind cannot rest. Ever." In the manga, he explains "Revenge only grows seeds of revenge," (which Scar didn't care for much until he found Winry pointing a gun at him, intending to seek revenge for her parents' deaths, as Scar was their killer in the manga). He later speaks on behalf of the Ishvalans at a refugee camp when Mustang and his men arrive looking for Scar. Scar's master was one of the few survivors of the covert op of which Martel was a part, and which triggered the Ishval massacre. He is never mentioned by name in the anime. He does exist in the Manga because he can be seen in a cameo in Chapter 58 for a brief period of time, and in chapter 72 in flashback when he stating that although they may (and should) not forgive the damage Amestris done to the Ishval, but they must not surrender to the hatred, and endure it, to sever the bonds of hatred, since they're human beings.
