Jack Black is coming back as Po for the fourth Kung Fu Panda film and the actor just hinted that he'll be preparing the next Dragon Warrior while facing off against his most formidable foe yet.

Jack Black was at CinemaCon last week where he reassured fans that Kung Fu Panda 4 is already in development over at DreamWorks Animation. The actor has voiced the tubby, martial arts master since the first movie came out in 2008.

Unfortunately, the upcoming film doesn't have a trailer yet, so Black went ahead and shared details about the project.

"Po faces his biggest challenge ever. Will he survive?" Black teased.

In Kung Fu Panda 4, Po will leave the Valley of Peace for the big city where a new villain, The Chameleon, will become the Dragon Warrior's newest adversary. What makes The Chameleon particularly dangerous is their ability to summon enemies that Po has fought before.

Po will be facing off against one of Master Shifu's previous students and a crane that wants to eradicate pandas. It is also possible that The Chameleon will usher in the return of Ian McShane's Tai Lung, Gary Oldman's Lord Shen, and J.K. Simmons' Kai.
