Gaston (KH III)

Gaston is a hunter who holds a grudge against Adam for "stealing" Belle away, even though she hated him. Now he's working with Maleficent to obtain Kingdom Hearts.

History in Kingdom Hearts
When Beast's Castle was destroyed before Kingdom Hearts I, Gaston was among the many inhabitants who fell into the dark pit along with the world. But like the Beast and Belle, Gaston refused to surrender himself to the darkness, and managed to keep his heart by the strength of his will. So, he wandered through the depths of the End of the World, fighting off against the Heartless that tried to attack him. Eventually, Maleficent found him by the beach and tried to recruit him to her Hellfire Club, but Gaston refused, saying he would find his own way out of the world without Maleficent's help. When Beast's Castle was restored thanks to the closing of Kingdom Hearts, Gaston was retuned to his world without any memory of his time in the Realm of Darkness.

It was after Maleficent met defeat in KH 3D that she decided to recruit Gaston once more to her Organization. This time, the egomaniac hunter agreed, hoping that the Heartless would help him finally take Belle for himself. Later on, Maleficent orders the hunter to infiltrate Xehanort's Organization, leading Gaston to don an Organization Cloak and changing his name to the false name of Atgonsx. Master Xehanort discovers the ruse all too easily and orders Ansem SOD to chase the intruder out. During the final battle in the Door to Light, Gaston is resurrected as a Heartless Lord by Chernabog and is summoned to attack Riku. The hunter falls to the blade of the wielder of Dawn only after a lengthy battle.
