Greed

Greed, as his name implies, is filled with and motivated by his avaricious nature. It could be said that the reason why he wanted all that life has to offer was because Greed didn't know exactly what he wanted from it, which fuels his desire to have it all. He is the only homunculus to defy Father, and the only one to openly taunt him. He has an easygoing, charismatic, arrogant personality and tends to do what he wants. He is also somewhat narcissistic, claiming part of the reason he doesn't use his ultimate shield to his fullest extent is because it masks his attractive face. He claims to not hurt women and to an extent, children. In addition, he states he never lies (though he tells only one lie in order to save Ling's life). While he normally possesses a calm, confident nature, when angered he can be rather impulsive and ready to go into a fight with those he feels have wronged him. However, he shows some capacity for adapting to his fights and is willing to protect his allies (and later innocent civilians). On a side note, he seems very charismatic and has shown good leadership skills, first with his chimera friends and later with Edward, Darius, and Heinkel, which he attributes to how he earns and deserve their loyalty in the first place. In addition, while he seems to see humans as weak and powerless, he never had sociopath tendencies or even hatred towards humans the way the other homunculi did. In the end, he even grows to respect their power and tenacity. However, deep down Greed wants nothing more than true friends who cared for him and for whom he cared for, though given his personality he often cloaks this by calling his friends and henchmen "possessions". This is first shown in Dublith where his chimera friends are killed by Wrath. While claiming he only saw them as possessions, he attempts to kill Wrath in retaliation, reasoning that Wrath killing his henchmen was like stealing from him. This is, in truth, not a lie; for what Greed treasured had been taken away from him and their loss deeply wounded his heart. Furthermore, he cries upon killing his own friend Bido and regaining his memories, then attacks Wrath at his home afterward, demanding an answer as to why Wrath destroyed his possessions. Being a living incarnation of avarice, Greed understands its nature better than anyone else, though Ed warns him that wanting too much can have dangerous results, just like what happens to people who attempt human transmutation. However, Greed countered by explaining that avarice is not about just money and power; no matter how noble or selfless someone is, everybody desires something.
