Dandy from Space Dandy.

Space Dandy practically feels like the absurdist bizarro version of Cowboy Bebop. The series both come from Shinichiro Watanabe, but Space Dandy is an overwhelming deconstruction of genre. Every episode indulges in a different staple of storytelling with radically different animation styles that take over each new planet that’s visited and every new alien that’s encountered. Space Dandy acts like an episodic anthology of sorts, but it reveals that it does in fact have a connected storyline. Repeated viewings help tie all of this together and accentuate the truly brilliant nature of Space Dandy’s structure.
