- Author Existence Failure: Part 2 marked the end of Michael Jackson's twelve year partnership with Sega, and was both his last appearance on the Dreamcast, and last video game appearance in general before his passing in 2009. Jackson's character was also removed from Space Channel 5 VR: Kinda Funky News Flash, and his vocals from "Saving Space Michael" were removed from the game as well.
- Descended Creator: Takashi Thomas Yuda and Ken Okazaki, who voiced Fuse and Noize respectively in the Japanese version, are part of the creative staff for both games. Yuda works in animation and Okazaki contributed to the character design department.
- Irony as She Is Cast: Apollo Smile, Ulala's first voice actress, is a professional dancer and choreographer playing the then-rookie space reporter. She was also a singer for a time, releasing several albums during the early 90s. And wore pigtails for the longest time.
- The Other Darrin: In the English version of Part 2, all of the returning characters except Ulala (and Space Michael) have different voice actors. Ulala eventually got Darrin'd for Kinda★Funky News Flash, with Cherami Leigh taking up the mic for her role. note
- Flashback with the Other Darrin: The intro of Part 2 shows several scenes from the first game. The voiceovers for these scenes have been redone by the Part 2 voice cast.
- No Export for You: Thanks to Michael Jackson's ill-advised interview with journalist Martin Bashir that aired just before Part 2's release in Europe (which led to a second round of child abuse allegations, and the eventual 2004 trial over them), the game was never released in the UK until it was included in the Dreamcast Collection for Steam and Xbox 360. Said interview also resulted in Jackson's likeness getting scrubbed from the game's "Special Edition" release in the USA, which was upheld for the 2011 re-release.
- Playing Against Type: Jaguar's Japanese voice actor usually does characters that are evil.
- Promoted Fanboy: Michael Jackson loved video games and had worked with SEGA in the past; after a SEGA exec showed him a build of their upcoming rhythm game Space Channel 5, he was so enthusiastic about the project, he wanted to be a part of it. Although the game's near-finished state limited him to just a couple of lines, he had a much larger participation in its sequel.
- Screwed by the Lawyers: Averted, in regards to Part 2. Despite his death, Michael Jackson still appears in the 2011 re-release of Part 2 intact, though his likeness has been removed from the game's cover art.
- Sequel Gap: A 19 year hiatus between Part 2 in 2001 to VR: Kinda★Funky News Flash in 2020.
- Uncredited Role: Michael Jackson provided beatboxing and vocals for his rescue mission music in Part 2, informally known as "Space Dance".
- What Could Have Been: Ulala was meant to have a cameo in Bayonetta, but legal issues came up that prevented her inclusion.
