He has recently moved to Los Angeles from his native New Jersey with his mother, Lucille, and takes up Karate with his Sensei, Mr. Miyagi, to defend himself from bullies. One of the main characters in Cobra Kai where he is married to Amanda and together have two children named Samantha and Anthony, and he runs a dealership with his wife called LaRuso Auto; he gets back into Karate and eventually becomes friends with all of his main rivals from the 1980s, Johnny, Chozen and Mike. |

Mr. Miyagi served in the US Army fighting in World War II before ending up as a maintenance man and later a karate master. While he doesn't physically appear in Cobra Kai as he passed away between the events of The Next Karate Kid and Cobra Kai, he does get mentioned numberless times (mainly by Daniel), is seen in photographs and newspaper clippings, appears through archival footage, and in Cobra Kai season 6, appears in Daniel's dreams a couple times. |

He was the top student of the Cobra Kai dojo back in the 1980s, a two-time defending champion of the All Valley Under-18 Karate Championships, and Daniel's high school rival, whom Daniel ultimately defeats in the All Valley. They meet again a few decades later in Cobra Kai. While he originally brings back Cobra Kai to help kids gain great strength and confidence, he later sees the negative effects John Kreese and the dojo's philosophy is having on many of his students. He quits being a Cobra Kai sensei in the season 2 finale, and opens his own dojo in season 3: Eagle Fang Karate.

In season 6, after escaping from prison, he forms a new Cobra Kai dojo in South Korea alongside Kim-Da Eun, the granddaughter of his original sensei.

In The Karate Kid II, after Kreese starts attacking Johnny for his second place win, Dutch doesn't attempt to try and save his friend and instead turns his back; this would be the last time Dutch is seen onscreen.

In the second film, he congratulates Daniel on his win. In the third film, he deducts points from Mike Barnes for his flagrant rule violation and warns him to stop.
