Story
The Adventure really-begins when Avatar Korra and her friends, who-are sometimes called "Team Avatar": the bending brothers Mako and Bolin, her non-bender girlfriend Asami Sato and their four little-friends, who-are sometimes called "The Littles": Daniella and Dylan Spellman and Coraline and Max Jones are entrusted-with a mysterious dagger "The Dagger of The Animal Spirits" (Rumored-to belong-to "The Kingdom of Half-Moon's Missing Princess") and are drawn-into a threatened-world - the war-torn planet of Etheria - Struggling-to survive the two different forces who-are battling for control there (The Horde, with its skillfully trained soldiers and advanced technology, has one goal: to conquer all of Etheria in the name of Hordak. The other force, the Rebellion, is made up of princesses and has been fighting to maintain harmony and freedom for all of Etheria's people.), Team Avatar meets one-young-girl who doesn't need a hero. In-fact, She is a hero.... Adora (A.K.A: She-Ra: Princess of Power!) and the leader of "the Princess Alliance", a group of other magical girls that all-oppose The Horde and it's wicked-leader, The Evil "Lord Hordak". Upon-pledging their own-allegiances, Hordak and army of soldiers meet the might of Team Avatar and the bravery of The Littles head-on! But their Second-in-Command and Adora's former best friend, Catra, seems to have a strange connection to The Dagger of The Animal Spirits.

Weird! (And if Team Avatar thinks that's weird, it gets-weirder) Can this cat-like servant of the forces of evil be connected to the magical blade?

Team Avatar soon-enough gets their answers when Catra discovers (on her own) that the dagger once belonged-to "The Princess of The Order of the Claw! (A long-lost "Magicat" Princess who-is rumored-to be-able to manipulate, or "bend", the four-elements of Nature "Air, Water, Earth and Fire", exactly-like the avatar)" (Who, much-to her discovery, everyone-else's shock, Team Avatar and the littles' astonishment, Is Her!!!!!) Then Catra's true-self is uncovered the second a horde-bot attacks her, she holds-aloft the dagger and strongly-proclaims "Jungle Beast, Spirit Unleashed!" and then (Right-in-front of Everyone, including her former right-hand woman "Princess Scorpia") magically-transforms-into "The Princess Everyone's Been Waiting For!" (Much-to her own surprise!!).

Now Filled-with a New-found sense of good (And rocking a whole-new look), Catra must learn to-master her new rebel-princess powers to-lead the rebellion into "the greatest-battle of all-time" to-fight the forces of pure-darkness (The Place she once called-home) and save her world!
