Can't say that feels too likely? Angela was never Todd's character -- she was Neil Gaiman's character, created for the issue of Spawn he guest-wrote way back in the day. The legal beef between Gaiman and Mcfarlane over Angela and Miracleman and everything else is a really long story, but I recommend reading up on it sometime, it has a great twist ending. Anyway, by that point botching Angela as a solo character would have stuck it to Gaiman far more so than Todd, and Marvel had no beef with Gaiman.That was Marvel's Angela, the Spawn angel they managed to negotiate away from Todd McFarlane & retconned her into Thor's long-lost sister. The concept had potential but they handed it off to a cunt who tanked it. Which may have been intentional, that could be a long overdue "fuck you" to Todd for the bad blood when he left Marvel after gifting them Venom and going off to make his own comic book and toy company to great financial success.
When an American comic book publisher fucks something up, it almost always happens just because American comic book publishers are run by a bunch of fuckups.
