Samurai Jack (2001)

S5E1 XCII

Fifty years have passed since Samurai Jack's last adventure, and the passage of time has not treated him well. With all the time portals obliterated by Aku, Jack has ceased to age—a consequence of his time-traveling escapades. Now, he faces an endless existence wandering the desolate landscape, tormented by memories of his past. To make matters worse, a cult of assassins has emerged, intent on hunting him down in the name of Aku, further complicating Jack's already cursed fate.
