The identical cowboy bebop and Naruto fight are both a homage to a Bruce Lee film, the Boondocks made it as a reference to Naruto.
And from a commenter on the topic from reddit “It’s called Sakuga animation. When the animation team needs to animate a scene that requires more skill than anyone currently on staff possesses, or they just want to make it really beautiful, they’ll call in a specialist to animate THAT specific scene.
In a series like Naruto, which has hundreds upon hundreds of episodes and is released on a weekly basis year-round, the standard animation is pretty simple, and not a ton of work gets put into the production of each episode, relatively speaking. Because of this, they need Sakuga animators to do the complex scenes. But, even in conventional and higher-quality shows, like Bebop, Sakuga animators are necessary, just because they are THAT talented and can really make a scene stand out and look flawless.
There aren’t a huge number of people who are talented enough to be free agent animators, so it’s totally plausible that they were the same guy.”
So there we go ouo Personally I think Boondocks and Cowboy Bebop looks better because it’s not as close up as Naruto, showing off more of the entirety of body movements used to deliver the kicks and punches
