*Princess Elise the Third[2] (ソレアナ公女エリス3世, Soreana Kōjo Erisu 3-sei?, lit. "Princess Elise III of Soleanna") is a character that appears in the Sonic the Hedgehog series. She is a human girl and the current sovereign of Soleanna, the sole living member of the principality's royal family.[3] The daughter of the Duke and Duchess of Soleanna, Elise lost her mother at a young age, and her father later perished as well in the failed Solaris Project, but not before sealing the Flames of Disaster inside of Elise's soul. Elise eventually grew to lead the principality, burdened by the pressure to never cry, lest the Flames be released.

Ten years after the Solaris Project, Elise was targeted by Dr. Eggman for the Flames of Disaster and her Chaos Emerald. Coming to her rescue, however, was Sonic the Hedgehog, who would save Elise multiple times and ultimately help free her from her heavy burdens.

Elise is a tall, teenage, human girl with fair skin, short red hair, and light blue eyes. Her outfit consists of an off-shoulder short white dress with short-puffed transparent sleeves and a ruffle rim at the top, a golden strap with crossed black edges and white flowers on the chest, and rhombus pattern with the Soleanna symbol at the hem. She also wears white evening gloves, silver earrings, a gem necklace, orange pantyhose, and red and silver high heel shoes.

As a child, Elise wore a layered, orange shirt with short-puffed sleeves with red and white triangle-patterned trims at the middle, and a pink transparent collar at the top of the shirt. Her pants were also orange, with red and white triangle-patterned trims at the end, a golden belt of black edges with a bow at the back, and red Mary Jane shoes.

Princess Elise is portrayed as a kind, gentle, and compassionate individual who genuinely cares for her people and her kingdom. She is also intelligent and aware of her role as a monarch, striving to be a worthy princess. Elise is willing to sacrifice herself to protect her subjects from Eggman.*
