*Queen Aleena is an anthropomorphic hedgehog with really long dark purple hair, as well as lighter purple fur and black eyes. She wears a gold crown with a single jewel in the center. While her armor covering her body is white, the jewel on the middle of it is cerise. She wears a white dress with a gold decoration on the skirt and a long yellow cape with a heart-shaped pendant on the front. Aleena is taller than her children. When Aleena was younger, she wore a pale pink and heart-shaped pendant made from a crystal-like material for her debutante ball. In To Catch a Queen, one of her scarves is a red scarf that matches the cloak she was wearing; Sonia correctly identifies is as belonging to her.

She wears a purple cloak when she is keeping an eye on her children. However, she was seen wearing a red hood when giving up the triplets in the theme song and in the episode, "To Catch a Queen".

Queen Aleena is caring and does her best to help her children - she once openly fired on a group of Swatbots and a Roboticizer to save Manic. Unlike Robotnik, she also cared about the people of Mobius; since; before Robotnik ruled, everyone lived peacefully and prosperously. In fact; if she was not risking the fate of her children, she would have joined them and become a Freedom Fighter; but she believes that; if she reunites; with her children; before the time is right, the prophecy will not come true and something horrible will befall upon them.

Queen Aleena appears to possess certain magical abilities, such as projecting her image to other locations and teleporting from place to place. Her golden crown contains a jewel that acts as a signal device; if separated from her, it will pinpoint her location. She also has a Royal Scepter, but she rarely uses it.

Throughout the series, the Queen has shown exceptional skill in stealth, as she was able to conduct operations, spy on the enemy, and sneak around without people, friend or foe, finding out.*
