- Adored by the Network: Cubix was rerun for years after it ended in 2004, returning in 2010 for the Toonzai block on the CW 4 Kids and lasting on Vortexx until late-2012. Justified, as the show is one of the few on each of the blocks to meet the FCC educational and informative regulations on broadcast television.
- Crossdressing Voices: Maddie Blaustein as Dr. K and the Mayor.
- Keep Circulating the Tapes: Only the first 3 episodes were ever released on VHS and DVD as a "Movie", the first two episodes were also released on a Sneak Peek DVD. The entire series was available on the 4kids website and Hulu for a while but has since been removed.
- Name's the Same: Odds are that this Dr. K won't get upset if you call the suits worn by the RPM Rangers spandex, or that the Solex featured in the show won't be used to power a laser cannon.
- Official Fan-Submitted Content: Towards the end of the first season, Kids WB held a contest for viewers to submit their own robot designs with the winners being used in the show. The two winning entries "Correctix" and "Demolishix" were featured briefly in "Tomorrow's Robot Today" and were voiced by their creators.
- What Could Have Been:
The show takes place in Bubble Town, 2040, where robots are ubiquitous. Everyone on Earth owns a robot, which can be programmed to be good or evil, according to the tendencies of its human master. A boy named Bobby discovers Cubix, a one-of-a-kind prototype in a junkyard and the two become fast friends. What makes Cubix unique is that aliens have hidden a special energy force inside of him, giving him extraordinary powers. The show will feature two running, intertwining plot devices: Bobby and Cubix battling the show's villains, Dr. K and Charles IV, and the aliens' quest to reclaim their lost power supply inside of Cubix.
- The original concept for the show was slightly different. Major differences included the fact that Connor was originally named Bobby and was depicted to be much younger and Charles had a much larger role a a recurring antagonist. To quote from this source
- A sequel was planned for a 2016 release date and would've featured most of the returning voice cast, but the project has since been cancelled. Not much is known about the cancelled sequel, expect it would've explored the concept of there being more than one Cubix model, and a much newer model dubbed C-Bix would be the central antagonist, along with a female model named Q-Tix who would be a love interest for Cubix.
