'Cobra Kai' Season 4 trailer turns old rivals Daniel and Johnny into allies

It seems that all roads lead to the All Valley Karate Tournament.

Netflix just released the trailer for the fourth season of "Cobra Kai," which sees the continuation of the rivalry between Daniel LaRusso (Ralph Macchio) and Johnny Lawrence (William Zabka).

In the trailer, the Miyagi-Do and Eagle Fang dojos join forces to take down Cobra Kai at the All Valley Under 18 Karate Tournament.

It looks like Daniel and Johnny have to try to bury their decades-long hatchet to defeat Kreese!

"Cobra Kai" picks up decades after the events of "Karate Kid," with Macchio and  Zabka reprising their iconic roles.

The upcoming season highlights a new All Valley Karate Tournament, over 30 years since the iconic 1984 tournament in the "Karate Kid" film.

"Cobra Kai" Season 4 will premiere on Dec. 31 on Netflix. —JCB, GMA News
