Snow White

Snow White is a character from the 1937 Disney animated movie, Snow White and the Seven Dwarfs. She is one of the Princesses of Heart whose heart was required to open the final door in Kingdom Hearts.

Story: Snow White's first appearance in Kingdom Hearts Birth by Sleep is when she is encountered by Terra in a meadow in her home world of Dwarf Woodlands, the girl not at all surprised to see the Keyblade wielder standing before her. Terra is told by the Queen to kill her, but he decides to put aside the plan. When the Unversed arrive, Terra summons his Keyblade to defeat them, but he also frightens Snow White and she flees into the woods in fear.
After Ventus arrives in Dwarf Woodlands and meets the Seven Dwarfs, he hears Snow White scream and finds that she has been cornered by Unversed and monsters that inhabit the trees of Dwarf Woodlands. He manages to take her to safety at the Seven Dwarfs' house where she stays until the Dwarfs come back. Her beauty and kindness persuades them to let her stay and keep her company.
As soon as Ven returns after checking the woods, she tells them what had happened when she fled into the woods, and about meeting Terra. The Dwarfs claim that it was Terra who'd sent the Unversed after her, but Ven disagrees and Snow White is willing to believe. After defeating the Mad Treant, Ventus heads to leave, but accidentally leads the old hag to where Snow White is.
By the time Aqua arrives, Snow White has already taken a bite on the poison apple and fallen into a deep slumber and placed in a glass coffin by the Seven Dwarfs. Later on, Aqua arrives with the Prince, who turns out to be Snow White's first love and the only person who can break the spell. He kisses her on the lips and awakes her from her slumber. She takes her farewell to the Dwarfs before the Prince sweeps her away.
During the ending credits, she is seen with the Prince and the Dwarfs in the meadow where her little friends throw flower petals around them. She and the Prince look at the petals in delight.
Snow White becomes a D-Link to Aqua and Ventus after their encounters separately.
