Greed

Greed, the "Ultimate Shield," is a formidable Homunculus known for his diamond-hard skin and insatiable greed. This ancient creature, despite his luxurious tastes and power struggles, shows genuine affection for his minions. Originally created by Dante, he rebelled due to his avarice, imprisoned in Lab 5 for centuries until an explosion freed him. With a unique ability to manipulate carbon, Greed seeks revenge against the other Homunculi and their master, forming alliances with chimeras rescued from military experiments. His dramatic backstory and complex personality make him a standout character in both anime adaptations.
