Sandy Cheeks

Sandy is a member of the Society and the official wielder of the Ultimagauntlets.

Appearance in Ultima
Sandy does not actually become an official Society member until The Crossing of Universes when Spongebob returns to Bikini Bottom.

Later down the line, Sandy returns to assist the Society during the Chaos Emeralds Arc revealing that she now possesses the Ultimagauntlets. How she obtained them has yet to be delved into, but will eventually be revealed soon. When the Ultimacrystal Arc began, Sandy replaced Squidward as the fourth member of Nicks group.
