Karis

Karis is a playable character of Golden Sun: Dark Dawn. She is a Jupiter Adept, but at the moment, her true relations to the other characters and to characters from past games is uncertain and can only be speculated on. She was first revealed for the game alongside her party members Matthew and Tyrell.

As a playable character
It is evident from trailers that she is one of the main party members that appears in battles in Dark Dawn, and she uses a fairly typical collection of Psynergy for a Jupiter Adept in Golden Sun games. The E3 2010 floor demo footage showing her in battle shows her selecting and using the Plasma Psynergy (whose appearance has apparently been changed to resemble what one might expect from the Bolt Psynergy series), and she is also seen to possess the Whirlwind and Impact Psynergies. Unlike previous Jupiter Adepts Ivan and Sheba, however, she has an all-new Jupiter-aligned healing Psynergy series named Fresh Breeze and Healthy Wind, the first Jupiter-aligned healing Psynergy of any sort. In the 2010 floor demo, she has the Jupiter Djinn Gust and Waft Set onto her, and also has the Sleep Psynergy.

Biography
In contrast to fellow party members Matthew and Tyrell, Matthew of whom greatly resembles his father Isaac and Tyrell resembling his possible father Garet, Karis' parentage is a much more contentious source for debate. Green is a hair color previously untouched by past Adepts (with the possible partial exception of Piers and his turquoise hair), and it is often stated that it comes from being the color "in between" the colors of the two parents' respective hair colors. Her purple eye color is important to note, too, which is shared only by Ivan (Sheba's eye color is green in all of her appearances in official artwork except for her in-game battle sprites in the GBA games). Complicating issues is the fact that she has the Fresh Breeze Psynergy that did not exist in previous games. Furthermore, it was confirmed from press releases that 30 years had passed in between Golden Sun: The Lost Age and Golden Sun: Dark Dawn and that the main characters of the game are the children of the main characters from the previous games, which may include Karis in this equation. For the time being, who were the father and mother of Karis cannot be appropriately determined.

At any rate, in the E3 2010 trailer, she and Matthew are seen at a town watching a Psynergy Vortex pulsating in the vicinity.
