Edison

Edison plays a very small role in the series, but it's an important one. He betrays Roy, who tries to tell him about Bradley, and rats him out to Bradley, putting Roy’s life in danger.

Envy

Envy is one of the homunculi. It’s disputed as to whether he is a girl or boy, but is referred to as a boy in the series. Envy can change his form, which is how he was able to trick Hughes into believing he was his wife. Envy’s true form is a little ugly green creature, though he is seen as a green dog thing at different points in the series.

Father

Father is the creator of the homunculi and is the mastermind behind all of the terrible things happening in Central. He is only seen for a few episodes, but he and Edward fight an epic battle towards the end of the series.

Wrath

Wrath is actually Fuhrer King Bradley, one of the most powerful military people. He acts as if he is a good guy, but works with the homunculi and threatens Roy on more than one occasion.

Gluttony

This little guy may look innocent, be he’s a force to be reckoned with. Gluttony is another homunculus, who has the ability to eat anything. He eats people most of the time, and ends up swallowing Ed, Ling and Envy with his stomach that can extend from his jaw to his belly button.

Greed

Greed, another homunculus, has the special ability to make his skin like a fitting suit of armor. He ends up dying, which is how Ling becomes Greed.

Lust

Lust is another homunculus, and is the smartest out of all of them. When Father isn’t around, she’s in charge. She can grow spikes out of her fingers to fight.

Sloth

Sloth shows up very rarely in the series, though he is a homunculus. He doesn’t play a huge part, but does fight a few of the main characters.

Pride

Though Pride is a little boy, he could easily be one of the strongest Homunculi. He has dark pointed things that he uses to fight Ed and Al. Pride is Wrath’s ‘son’ in the story, though it’s revealed that homunculi cannot have children.

Kimblee

Kimblee is an alchemist that fought in the Ishvalan war. He was in possession of a stone and went insane with the power.
