Desna and Eska

"water"

- You amuse me. I will make you mine.

Desna and Eska are the twin son and daughter of Unalaq and the cousins of Avatar Korra. Eska is the current Princess of the Northern Water Tribe. They also traveled to the Southern Water Tribe for a festival which Korra attended.

Korra finds the twins annoying, as they look down on her Southern Water Tribe heritage, thinking she is a "rube", despite being the Avatar.

Abilities
The twins are very powerful waterbenders, able to cooperatively accomplish incredible feats of waterbending, such as launching entire icebergs at opponents.

Trivia

 * Desna and Eska have been described by the writers as "androgynous, creepy twins".
 * They are the third pair of twins shown in either series, the first being Poi and Ping, and the second being Lo and Li. However, they are the first twins of different genders.
 * They are also the first known twins to both be benders, as only Poi was an earthbender, and both Lo and Li were not firebenders.
 * They are also one of three known brother-sister pairs from the Water Tribes; the others being Sokka and Katara, and Rafa and Misu.
 * The twins seem to be able to communicate without saying a word to each other.
 * Bolin is infatuated with both twins, as he initially failed to realize that Desna is male.
