Cobra Kai showrunners discuss the selection process for bringing back characters from the Karate Kid universe, focusing on the story's progression and adding value to the narrative. The final season of Cobra Kai on Netflix is highly anticipated as it wraps up the story of Daniel LaRusso and Johnny Lawrence after 40 years. The close relationship between Ralph Macchio and William Zabka off-screen, initially strained but later reconciled, significantly influenced the success and authenticity of Cobra Kai, culminating in a deep bond that mirrored on-screen chemistry.
