Buttercup Raiko

Buttercup Raiko is the wife of President Raiko, and became the First Lady of the United Republic of Nations following her husband's inauguration in 171 ASC, shortly after the dissolution of the United Republic Council.

History
Buttercup and her husband attended the finale of The Adventures of Nuktuk: Hero of the South as honored guests, having been invited by Varrick in hopes of convincing them to help support the South in the Water Tribe Civil War. Buttercup was flattered by Varrick's many compliments upon their arrival, but remained silent as her husband reaffirmed his position to remain diplomatic in internal Water Tribe conflict.

In the middle of the movie, Buttercup and her husband were nearly kidnapped by a trio of waterbenders, but were promptly saved by Bolin, who subdued the attackers with his earthbending. The president and his wife were secured by several of Chief Lin Beifong's officers to ensure their safety, while Varrick was apprehended for masterminding the attempted abduction.
