Mordin Solus is a fictional character in BioWare's Mass Effect franchise, who serves as a party member (or "squadmate") in Mass Effect 2. A salarian (one of Mass Effect's alien races) physician and life scientist who was once a member of the salarian intelligence organization Special Tasks Group ("STG") earlier in his life, Mordin is depicted as a fast-talking and affable individual who is initially guided by scientific principles and logic, but later changes his mind and adopts strong moral standards as well as a respect for all forms of life.
Within the series' narrative, Mordin helped create and distribute measures to strengthen an artificial population control plague, named the Genophage, used against the krogan, a fast-breeding warlike alien race. He returns in Mass Effect 3, where he returns to STG as a special consultant, whilst also working as an inside source for Clan Urdnot, the dominant kinship group among the krogan. His goal is to develop a cure for the Genophage in response to the galaxy-wide invasion by the antagonistic Reapers and intends to distribute it in the atmosphere of Tuchanka, the krogan homeworld. The ninth issue of Mass Effect: Foundation explores the backstory behind his contributions to the strengthened Genophage.
Mordin is voiced by Michael Beattie in 2 and William Salyers in 3. His race was conceived as a variant of the grey alien archetype, while the character is designed with clothes that hint towards a labcoat. Inspiration for his face was taken from Clint Eastwood, whose cinematic acting roles a brilliant yet also a competent soldier. David Kates composed his musical theme, a highly electronic piece in comparison to some of 2's more orchestral pieces.
The character has been positively received, being nominated for three "Best New Character" awards and earning numerous placements in "top character" lists. At one point in the second game, Mordin sings an alternate version of Gilbert and Sullivan's Major-General's Song; numerous critics considered it one of the trilogy's best moments. As with other Mass Effect squadmates, merchandise for Mordin has been made, such as a bust.
