Team Kakashi (Kakashi, Naruto and Sakura) are sent on a mission to assassinate Republic City's council members. On their way they run into Team Korra (Korra, Mako and Bolin), who learn of their plan and are convinced that they are working for Amon. Everyone in this fight is willing to fight to the death, but otherwise they are in character.
Fight takes place on a riverbank (there is plenty of water).
Speed is equalised and all Naruto characters are as they were at the start of shippuden. Kakashi cannot use his mangekyou, and Naruto cannot use the Kyuubi.
After 2 minutes Tenzin and Lin will arrive to reinforce the team. After 10 minutes Korra will go avatar mode.
