This thing again? Crono is the name in the US version. Chrono is his Japanese name. There's a difference. Smash Ultimate's site sometimes uses the Japanese spelling(but not it Katakana, Hiragana, or Simplified Chinese) instead. So the idea it uses Chrono instead of Crono has a possibility.
Graizen's correct. Citing the US Chrono Trigger website is meaningless(which wasn't even cited, just a GameFAQs topic). It applies to the official US spelling. Of course it's going to list that. Just like Isabelle is listed on the EN-US Smash Ultimate site when you look at the physical site itself. It has nothing to do with the coding alone. On the US sites, Crono will be viewable till a US remake redubs his name as Chrono. The French version also has Chrono, literally listed among that GameFAQs topic. I'm not sure if people even understood the point Graizen was making anymore. That the site's JSON files used Chrono's Japanese spelling. That was it. Which is why the leak in question doesn't have any spellings actually wrong.
Doesn't give it any real credibility, it just killed the only real thing against it. It's still pretty easy to claim regardless, heh. JSON files can be made by people, though the only picture given was just showing how easy it was to display the words in the coding on the website, not showing a literal leak of an updated website. Leak still is hard to swallow on its own due to just being a text leak in practice, but that's the main thing against it at the moment(that at least makes sense). Other things to think of is if Brave is Fighter 72, which means "Brave" would have to be Crono. Considering Jack seems to be significantly related to Joker, I doubt any heroic character could be Brave. I'd argue it should have some remote significance. It doesn't have to even be a lot, just something that actually would tie to the character. Like, anyone could be courageous. But it should tie to them in various materials. Erdrick's Hero class is effectively called Brave in a way, then there's the whole Brave(Courage) stuff like the Agumon line. Those two directly tie into the characters. I remember some group or whatever(I forget the details) that relate to Yuri from Tales of, which is another example of it being possible. I realized that there was no good way to tell how Brave should relate to the character as soon as Jack wasn't obvious what it meant for Joker(playing cards? Jack of all trades? Jack Frost?), but multiple ways. So as long as the character has a legitimate relation to the word brave(or its synonym courage, perhaps), it feels at least worth noting as a possible character. Of course, that's imo.
