Anna appears somewhere in every primary entry except for Fire Emblem Gaiden. She is a red-headed young woman and is commonly seen in a trademark pose with her index finger rested at her face and wearing a sly smile.
Anna is traditionally a non-playable character who appears throughout variousFire Emblem games as a guide, cameo, prompt for suspending map data, or merchant in one of the Secret Shops. In the GBA games she also appears in the Link Arena and also in the prompt before game data is erased. In Fire Emblem: Path of Radiance and Fire Emblem: Radiant Dawn, she hosts the in-game tutorial and is depicted as a Pegasus Knight, although she never attacks. This is the first time she appears as a unit. She also appears in the beginning of Fire Emblem: Shin Monshō no Nazo ~Hikari to Kage no Eiyū~, guiding the player in the creation of the Avatar.
Anna appears in dialogue as an NPC in Fire Emblem: Ankoku Ryū to Hikari no Tsurugi, its remake Fire Emblem: Shadow Dragon, Shin Monshō no Nazo,Fire Emblem: Genealogy of the Holy War, and Fire Emblem: Rekka no Ken. In all of those games, she appears to have a close relationship with another recurring character, Jake. Anna and Jake are in fact engaged in Genealogy of the Holy War.
While not a single individual, all versions of Anna have shown similar traits amongst each other. As merchants by trade, they are always found wherever deals are made and always carry the highest quality goods to make money. All Annas are aware that their sisters and cousins highly resemble each other and have the same name, but they seem to be able to distinguish each other with little trouble.
The two playable Anna's in Awakening and Fates are shown having a little more willingness to use slightly shady tactics to sell their goods. However, they will only go so far for a profit and even regrets using those tactics. For any Avatar who marries her, they quickly find out that her love of money trumps her love of them, but she still shows that she loves them nonetheless. [Source: wikia]
