Due to the fact the Eggman has promised his creations that one of them would become an "Ultimate Life-form" and that none he had made so far fulfilled that prophecy, Eggman decided to create another artificial life-form using energy, powers, and DNA structures from Blaze, Wave, Silver, and Shadow. His newest creation, first called "Project: E-451" took a total of nearly twenty months to complete. After his creation was finished, it did not act as Eggman expected. At first, Project: E-451 was destructive and violent; it would incinerate anyting it touched. As a result, E-451 was contained and restrained for months, until Eggman gave it special gear to minimize its power. E-451 was named "Daybreaker" by Sonic and his friends when they first saw her wreaking havoc in the Green Hills.
E-451, or Daybreaker, is a white Phoenix with gold-orange tiger stripes, deep red and yellow eyes, flaming hair, tan fireproof gloves and skirt, and gold armour with a red ruby on the chestplate, just for aesthetic.
- The "E" in her code name stands for "Eggman".
- The number 451 in her code name is a reference to Ray Bradbury's novel title, Fahrenheit-451, in which it is said that paper starts to burn at a temperature of 451°F.
- Daybreaker's name and attire is inspired by the villain, "Daybreaker", from the My Little Pony franchise.
