He is the son of Alex Louis Armstrong and my only FMA character
Blaine is alot like his father being quiet over emotional and goofy but very serious in battle. He will usually protect anyone that needs to be protected since its a vow he has made to himself.
His family's brass knuckles
Blaine was born into the incredibly strange family of the Armstrong's. He was taught to always stay in the best shape possible and always protect other's. His father took very good care of Blaine making sure he was never bratty or anything like that. He idolized his dad when he was young wanting to be just like him but has since wanted to be his own person. His father never told him who his mother was or where she was. Blaine always assumed that she was out working all the time and that he just never was able to see her or hear from her. His father taught him all about alchemy and even gave him the brass knuckles that he used also. Blaine learned to use the brass knuckles to enhance his alchemy power and uses them often know.
