Sara and Kara (voiced by Tara Strong) are twin Oracles who first appeared in "Dragon Breath" in Season 1. The two are friends of Jake's and recurring characters in the series. They are great descendants of the Oracle of Delphi of ancient Greece.
Because of their ability to see the future, Sara and Kara are considered a part of the magical realm and live there along with other magical creatures. But, aside from that, they are perfectly normal teenage girls.
