- Actor Allusion: A very subtle one, if at all intentional, to Keiji Fujiwara in the form of Axel Hughes.
- Cross-Dressing Voices: Mikako Komatsu as Joey.
- Development Hell: Despite all the hard work Stan Lee put into making the anime version accessible to Western audiences, infighting between Buena Vista Entertainment and Studio BONES have ensured an English dubbed version won't be coming any time soon (well, not outside Malaysia anyhow). As of August 2012, there is no news of a release (whether on disc or broadcast) in the US or any English-speaking region.
- Six years in at the time of this writing (2019) and still no word. What's more with Stan Lee's death, it doesn't look like sequel or continuation will be forthcoming either.
- I Knew It!: Viewers correctly guessed that Will was the one in the overcoat and hat.
- Name's the Same: Voice actor Sumie Sakai shares hers with a Japanese professional wrestler.
- No Export for You: Despite this being one of the most American anime you could probably watch, this strangely hasn't received a release stateside.
- Made its debut in Super Robot Wars with Super Robot Wars UX.
