Wrath

Wrath (ラース, Rāsu) is a Homunculus made by Father (in the manga and 2009 anime series), and by Izumi Curtis (in the 2003 anime). In the manga this Homunculus is revealed to be Führer King Bradley, while in the 2003 anime it is an original character.
Being a human-based Homunculus, Wrath has the ability to physically age, which enabled him to pass off as an average human, allowing him to assimilate within the general population without suspicion. Despite being a Homunculus, Wrath's unique creation has resulted in the fact that the Philosopher's Stone which makes him inhuman is comprised of only one soul - his augmented physical abilities such as his remarkably high strength, speed, and agility are all his own, rather than being a product of the stone. However, due to the fact that his Philosopher's stone contains only one soul, he does not have the immortality and regenerative abilities of his monstrous brethren.

A formidable opponent in battle, Wrath strongly favors using swords, which he wields with deadly accuracy thanks to his unique gifts and lifetime of training, to the point where he can wield five blades simultaneously. Already a supreme swordsman and martial artist, he is made even more dangerous by his Ultimate Eye, which he conceals with his distinctive eyepatch. Though the details of his eye's abilities have not been elaborated on it apparently grants him tremendously accurate vision and the ability to read and predict practically any move his opponent could make as well as the minute details and movements of his general surroundings. The eye's only weakness is that when there is a physical obstacle blocking its path, it is unable to provide Wrath with the predictions it normally would. Additionally, he has stated on multiple occasions that, while his eye is capable of reading any situation, his own aging body is often unable to keep up with the projected courses of action that his sight ability proposes to him.

Nevertheless, Wrath remains as one of the most powerful characters in the series, capable of fighting evenly against both the second Greed and Fuu using only two daggers as well as being able to defeat the first Greed with ease. And even after being severely injured by Buccaneer and Greed/Ling, he proves himself to be more than capable of fighting evenly and even overpowering Scar almost killing him twice (even though his body was starting to fall apart due to his earlier fight). He has also demonstrated himself to be extremely intelligent and skilled in military weapons, as he was able to destroy a Briggs Tank with only a sword and a hand grenade.

The fact that his Philosophers stone is merged with a single soul also means he cannot be easily detected by people from Xing unlike his fellow Homunculi, giving him a deadly element of surprise in battle with them.

Among the Homunculi he is second in power only to Pride.
