Philip Gargantos Armstrong (フィリップ・ガルガントス・アームストロング) is the current patriarch of the illustrious Armstrong family and the father of Major General Olivier Mira Armstrong and Major Alex Louis Armstrong as well as civilian daughters Amue, Strongine and Catherine Elle.
Although a bit of a windbag, Philip Armstrong enjoys telling stories of his family's grandeur and his own eventful military career to anyone unfortunate enough to be his captive audience. It would seem that Philip is the one who passed on the habit of speaking about past generations of the Armstrong family down to Alex.
Being a former General, Philip seems (for all his hot air) a rather insightful man, inferring immediately from Olivier's demands for the Armstrong estate that Amestris would not be a safe place to stay and taking his wife and daughter Catherine off to Xing on an "extended vacation".
Trivia
- In both anime, the Japanese and English versions, Philip Armstrong is voiced by the same actor who also voices his son Alex.
