The long awaited "Cobra Kai" Season 4 trailer has been released. Yes, Miyagi-do and Eagle Fang Dojo may unite to end the Cobra Kai Dojo once and for all, but Cleese has an ace up his sleeve in Terry Silver.

And in this trailer, we get to see Terry's new look, unveiled in the previous clip. Silver has shed his leather jacket and greasy, gathered hair and transformed into a sophisticated look of sport coat, aviators, and dress shoes. But he is still fighting, ready to train a new generation. And he is a little hard on one of them. See:

Yes, unsurprisingly, Silver is giving Robbie Keane (Tanner Buchanan) a no-holds-barred lesson. Could it have something to do with the fact that Robbie is Johnny's estranged son, whom Silver probably does not trust?

For those who don't remember, Silver (Thomas Ian Griffiths) appeared in the "Karate Kid" film world in "The Karate Kid Part III," funding the old Cobra Kai dojo for John Crease (Martin Cove). The show's creators Josh Heald, John Hurwitz, and Hayden Schlossberg were quoted by Deadline as saying that the show has been building up to his appearance for a long time. They said, "Since the series began, we have carefully staged the right moment to unleash Terry Silver, co-founder of the Cobra Kai Dojo, into the universe. That moment is now. The entire world cannot wait to experience the majestic return of Thomas Ian Griffith"

.

Elsewhere in the trailer, we see that Johnny's rather unorthodox training methods are causing a bit of concern from Daniel. Cleese objects to Johnny's decision to work with Daniel and is a bit uncomfortable about whose idea is best for everyone in the combined camp of Miyagido and Eagle Fang.

The end of the trailer reminds us that the stakes are higher for this year's All-Valley 18 and Under Karate Tournament.

One of Netflix's best shows, "Cobra Kai," will return for Season 4 on December 31, 2021. As for shows that won't last that long, Netflix just canceled one of its biggest shows of 2021.
