Anna is a resident of Soleanna in Sonic the Hedgehog (2006). She is one of Princess Elise's two ladies-in-waiting, with Sophia being the other. Her duty is to serve and protect Elise, and she is therefore very watchful of her, accompanying the princess wherever she may go. According to Sophia, Anna is very knowledgeable about Soleanna.
In the Silver Episode, Anna plays an important part in Silver's fourteenth Town Mission, which is provided by the Soleanna Royal Guards. A horde of Badniks have attacked Anna in Castle Town and are trying to get a special secret about Soleanna from her. The guards promptly arrive at the scene to help her, but are unable to handle this dangerous issue, so they ask Silver to destroy the robots and escort Anna to the safety of the Forest.
Anna also appears a few times in the Sonic Episode, though only to provide advice to Sonic about upcoming levels; she does not appear in any missions.
