Maybe a fanfiction, but in Marvel itself, you can count with your fingers the amount of alternate universes where Peter and Felicia end up together for a while and you wouldn't need to use more than one hand, even less the ones where they stay together.
A solicit for issue#3 vaguely says that she'll have a trick that lasts "far beyond King in Black", assuming they're not lying, this could be talking about Anti-Venom.
Either way, read the issue#1, it's honestly funny how Felicia was just doing her thing, then King in Black suddenly interrupts her thefts.
Interesting she stole the Spider-Mobile from somewhere too
.
Felicia says she stole from Strange twice, so King in Black is happening after Last Remains, then again, not like Marvel would remember a detail like that lol.
Also funny that they say that Felicia has experience in dealing with symbiotes because of Eddie and Lee Price, but they don't mention Carnage at all, and while Venom vs Carnage can be considered more obscure (Since that story was only done to introduce Toxin, but Toxin wasn't really popular), she did deal with Carnage back in Maximum Carnage, so it's at least twice, and one of them was kinda major.
Either way, this was fun enough, and it made me realize that the heroes really should've gone to Alchemax to get Anti-Venom suits, or at least if making those is complicated (Don't remember the detail of how that happens, only remember that Flash got it back in Venom Inc somehow), get whatever it was that chemical that made the Anti-Venom suit back in Venom Inc to begin with and throw that shit in the symbiote dragons to hurt 'em, looks even weirder they didn't do that 'cause they did somewhat know in advance that Knull was coming, and they did kinda prepare for it, so Anti-Venom would be really helpful...
