Princess Elise
From Sonic Earth
Princess Elise The Third is a character from Sonic the Hedgehog as the princess of Soleanna. She is voiced by Lacey Chabert in English and Maaya Sakamoto in Japanese. When she was seven years old, she was with her father, the Duke of Soleanna, when he tried to extract energy from Solaris, the sun god of Soleanna. The experiment accidentally splits the deity in two entities, but the Duke manages to transfer one half, Iblis, into Elise. He then tells her that she must never cry, as that would release the destructive Iblis, also known as the "Flames of Disaster".
When she first met Sonic, she thought he was the 'silver' hedgehog she saw as a child. It's later revealed in Silver the Hedgehog 's story that he and Shadow went back in time to uncover the truth of Solaris. Shadow encased Mephilis in the dark sceptor while Silver helped the young Elise after Iblis was sealed within her. The blue Chaos Emerald that she's had since she was a child was given to her by Silver.
In the present time of the game, Elise celebrates the Festival of the Sun in Soleanna. Doctor Eggman then attacks the city and kidnaps Elise, out to get the power of the Flames of Disaster she keeps inside her. Sonic quickly chases after them. Elise is later killed when the Egg Carrier explodes due to unstable engines, but Sonic and Silver use Chaos Control to go back in time and save them.
In the "Last Story", Sonic is killed by Mephiles the Dark. Elise breaks down and cries, releasing the eternal flames of Iblis, who fuses with Mephiles into Solaris. After Sonic's friends find the seven Chaos Emeralds within the distorted reality, Elise uses their powers to heal Sonic with a sort of 'kiss of life', the energies reviving him as well as transforming him into super form. Super Sonic thanks Elise, then gives some of his power to Shadow and Silver, transforming them into Super Shadow, and Super Silver. After Solaris is destroyed by Super Sonic, Super Shadow, and Super Silver, Sonic and Elise go back in time to when Solaris was just a flame. Elise takes the flame and tells Sonic that if it blows out, the flame that will become Solaris in the future, it will result in her and Sonic never meeting. Though she doesn't want their friendship to end, Sonic convinces her to abandon their meeting. With tears in her eyes and a small smile, Elise gently blows Solaris from existence, thus erasing the whole game's events and happenings. Afterwards, the timeline changes so she is never kidnapped, and never meets Sonic. All the events of the game never happened.
