Marder said that when he started, Mr. Nimbus was in a lost "Rick and Morty" episode, "but everyone internally was like there's this character, he's amazing ...the nemesis [of Rick]. This is one he's got a unique relationship with him, he's definitely ashamed of him being his nemesis to some extent, looks like they have a really storied past." After he called it a "super-cool episode," Chalke asked about where they got Mr. Nimbus' look. "David Bowie was definitely an inspiration there," Marder responded.
Harmon then chimed in, saying, "I think it started with the question, how could you be into Sub-Mariner in high school without getting beaten up every day, and then we asked ourselves, 'What if the goal was to get beaten up?'" Which, honestly, is a pretty hilarious thought right there, and goes oh so well with the Bowie vibe: the androgynous look, the mullet-style hairdo, colorful eye makeup, and body decorations.
Mr. Nimbus, a play on the word "nemesis," sports a thin build that is a bit of a departure from the Marvel character Sub-Mariner, who usually sports gold cuffs, green Speedo-style swimwear, and not a whole lot else, although he does carry a trident that's similar to Mr. Nimbus'. Once you see it, you can't really deny the similarities. Sub-Mariner, also known as Namor, is a half-Atlantean, half-human who hates humans but has also fought alongside the Fantastic Four and various Avengers. Yeah, Mr. Nimbus is definitely a Sub-Mariner style guy you could beat up. Unless you're Rick, that is.
