Mercedes von Martritz is a major character in Fire Emblem: Three Houses. She is a member of the Blue Lion house who is proficient with Light Magic and Dark Magic.
She is voiced by Yumiri Hanamori in the Japanese version and Dorothy Elias-Fahn in the English version.
Mercedes is a 22 year old woman with long blonde hair (originally brunette) done into a low ponytail on the left side and blue eyes. She wears a black and white dress with a cloak, dark blue stockings, and brown boots.
In the post-timeskip, she wears a hat with a veil, blue earrings, beige and dark brown dress, and shorter haircut.
Mercedes is a very positive person. Despite all the awful things that happened to her, she almost always acts calm, constantly trying to help anyone who needs it. She has a motherly personality and can't ignore people in need. Due to her being very religious, she lets people tell her what to do, saying it is the will of the goddess. She is also a bit scatterbrained and very clumsy. She is still capable of getting angry, though, as seen in her support with Lorenz. Overall, she simply is always trying to help people in need.
She likes baking sweets, ghost stories, needlework, painting, reading, flowers and adorable things. She dislikes spicy foods and exercise. She also hates crests due to her bad experience with them.
Mecedes was born to Baron Matritz of the Adrestrian Empire. He died that year, so Mercedes's mother remarries Baron Bartels. The two have a son named Emile a year later, who bore a crest. However, Baron Bartels abandoned Mercedes and her mother due to him getting a child with a crest. Mercedes was eventually adopted by a merchant in the Kingdom, where she grew up as a commoner.
Before going to Officers Academy in Garreg Mach, she attended the Royal School of Sorcery and befriended Annette. Mercedes than joined the Blue Lions. She joins Byleth if Byleth chooses the Blue Lions house. If not, she can be recruited into either of the other houses if Byleth has enough Magic and Bow proficiency.
If the Azure Moon route was chosen, Mercedes joins the rest of the class at Garreg Mach Monastery after the time skip. After liberating the country from Cornelia, Dimitri and his forces attack fort Merceus. The Death Knight is mortally wounded during the battle. Mercedes removes his mask, revealing himself to be her half-brother Emile. She then comforts him as he dies in her arms.
If the Crimson Flower route was chosen, she will join the Black Eagle Strike Force if she was recruited before the time skip. If not, she will be one of the generals who assists Dimitri in Tailtean Plains. She dies in the conflict. If the Verdant Wind or Silver Snow route is chosen, she will return to the monastery if recruited. In the Verdant Wind route, she will appear in Gronder Field with Dimitri. She can be killed in the conflict, but her fate is unknown if she survives.
If any route other than Crimson Flower is chosen and Caspar is recruited, Caspar tells Byleth that a small battalion led by the Death Knight are scouting the monastery. Mercedes hears the conversation and also goes with Caspar, thinking that the Death Knight might be her half-brother Emile. The Death Knight's forces attack, but he does not enter the fray. When all of his forces are defeated, Mercedes confronts the Death Knight, who confirms that he is Emile. Mercedes tries to convince Emile to join her, but Emile refuses, giving her the Rafail Gem before he leaves.
