Character description
Robin is the is the player avatar and a main character of Fire Emblem: Awakening. In the beginning of the game, Robin is found lying in an open field by Chrom, his/her sister Lissa, and his/her bodyguard Frederick. They find out that Robin has amnesia and remembers nothing besides his/her own name, Chrom's name and his/her incredible knowledge and experience in fighting battles, which Chrom experiences firsthand after they manage to save a small settlement despite the strength and numbers of the enemy. Frederick suspects Robin of being an assassin due to him remembering Chrom's name before his own, but Chrom is convinced of Robin's good intentions and invites him/her to join the Shepherds as their chief tactician, with the two quickly becoming close friends. Ylisse, Chrom's home country, is then faced with a war against Plegia (which is later revealed to be Robin's home country) and another against Valm two years later, both in which Robin's tactical expertise proves very helpful, especially given Ylisse's limited number of soldiers. There is also the constant threat of the Risen, undead soldiers who terrorize parts of the continent of Ylisse. As the Shepherds continue to fight and recruit more capable members, Lucina, Chrom's daughter from the future, properly introduces herself to them, having only met them while she was disguising herself as Marth. She travelled back in time to warn them about the revival of the Fell Dragon Grima after having her own world on the brink of destruction courtesy of him. Robin, Chrom, Lucina, and the rest of the Shepherds make it their new mission to prevent the Grima of the current timeline from surfacing.

In game, Robin starts in the Tactician class exclusive to him/her, his/her potential children, and DLC characters, which enables them to attack with magic tomes as well as swords. As the avatar character, Robin and his/her potential children can switch to any starting class the player desires using a Second Seal (aside from Lord, which is exclusive to Chrom and Lucina), making for one of the biggest skill pools possible for a single character. Robin can also support with every other character (as could Kris previously), and marry any opposite gendered character the player wants, including the future children of other Shepherds that are met via Paralogues (side stories) as more characters within the Shepherds marry each other. Robin's customization focuses more on appearance and even features several options for voice.
