Yeah, I also read this article...
I'm a newcomer (actually this is my first post here) and I feel utterly disappointed how Disney/Marvel tend to disrespect certain characters (a great example is D-Man) bc they won't appear in future MCU projects or simply bc writers/editors have no idea what to do with them.
Anyway, if Blue Marvel has indeed any chance to appear in a future movie (or TV show) I'd be pretty glad bc I really like Superman-type characters.
