*Lady Alicia Acorn is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. She is a mobian squirrel-chipmunk, the wife of Maximillian Acorn, mother of Sally and Elias, and former queen of the Kingdom of Acorn. Prior to Dr. Ivo Robotnik's coup, she and her son Elias were sent away from Mobotropolis for their safety but ended up crash-landing on Angel Island. There, Alicia fell comatose and remained so for years under the watch of the Brotherhood of Guardians. She was later found by the Royal Secret Service and brought back to Knothole, where she underwent therapy through various means before finally being revived. Since then, Alicia was constantly at her husband's side, often advising him and their children in the process of rule. Even with Max's retirement she remained a powerful force, serving as one of Elias' closest advisers and supporters. As her husband's health deteriorated, Alicia generally remained by his side to care for him.

Alicia is almost the spitting image of her daughter Sally in terms of physical appearance, the only differences being Alicia's different hairstyle and the later addition of wrinkles to her face. In her youth, she was also the splitting image of Julayla. While in cryo, she was often depicted in a long vest-like garment and later, a plug-suit of sorts. She was briefly shown wearing a hospital gown and Sally's blue vest. Her attire usually consists of orange dresses accented in gold jewelry with a golden headpiece or tiara. One particular dress featured elaborate trims and a hood.

Alicia loves her family deeply, and was particularly distressed when Elias ran away. While she was not completely pleased with her husband's attempts to marry Sally off, she also believed that certain traditions would leave Sally with little personal choice, having had a traditional royal marriage herself. As Max's condition deteriorates, she became increasingly concerned with his attitude, particularly in regards to his relationship with his children.*
