Aña is the disciplined, seasoned leader of the AUA. She insists on being addressed as "Commander Sharapova" or simply "Commander." She does her job well in ensuring that everyone is doing their job. She is 46 years of age with green eyes and faded brown hair arranged in a loose but professional bun. She is quite tall for a woman and seems to look taller than she really is due to her dignified posture and way of striding down the corridors of Agency Headquarters as if to say, "Don't you dare bother me; I mean business." She is normally seen in dark teal uniform typical for most Agency workers, but hers is a shade lighter to set herself apart from the rest. Aña is Russian, so she speaks with a strong accent, but she speaks English fluently and is easily understood.

She is very fit, possibly as result of plenty of exercise, tirelessly gliding about the Agency building, shouting out orders. As long as Chief Sharapova is around, there is something to be doing. She is disgusted by any kind of laziness. The best way to get on her bad side without directly insulting her is to slack off. Even the smallest degree of disrespect, even if unintentional, is returned with her infamous "scowl of death." Although she is easily annoyed, she is not short-tempered. She is calm under pressure and can make decisions even when she is rushed. She is willing to listen to and heed suggestions, but she won't hesitate to inform someone if their idea is complete rubbish. She can be prideful and finds it very difficult to admit mistakes. She's the type of person who most people find difficult to form a friendship with. She doesn't like trivial chatter and if you don't have anything useful to say, she'll sharply tell you to shut up and get back to work.

Before the AUA, she was an accomplished Russian biologist. She stumbled across her (now deceased) predecessor, Dr. Joseph Seong, at the laboratory she worked at and was instantly suspicious of his random visit to the lab. Noting her exceptional performance, Dr. Seong shared with her (and a handful of other lab workers) his discoveries of the digital dimension. Needless to say, she was not convinced until he proved it by accidentally opening a gateway to the second dimension. She was pulled into the gateway, but the temporary opening closed, trapping her in the second dimension during the Ten-Year War. Among her adventures in the digital world, she found a digiegg of a fallen digimon warrior. When she held it, her life energy was transferred into it and it hatched into a white demimeramon named Enka. Together they began to develop their magical abilities and techniques until after four days, they found another temporary tear in the barrier. They returned to the first dimension together, not wishing to part, for the two had formed a strong partnership. By that time, Aña had already helped Enka digivolve to his in-training form of kyaromon.

After their return, Aña, Enka, Dr. Seong, and a ragtag group of scientists founded the AUA. Since working for Dr. Seong, Aña worked her way up over the years to become his second in command. After his tragic death, she took his place as Commander.
