I really don't want to see something like this, but I'm afraid that's the kind of things you can always expect from a "What If?". Since it's not the Mainstream continuity, that means it can happen either the best or the worst.
I just hope that some elements from this zone will survive. Basically, Spider-MJ and classic Agent Venom (I like this look much more than the new cosmos-one).
I'm honestly hoping the scenario I outlined isn't what ends up happening, either. And yeah, Spider-MJ would be great to take into the "All-New" Marvel. I'm not that fussed about Venom even if the new look is gonna take a long time to grow on me, mostly because I love what it symbolizes --- a vindication of the symbiote, proof it was never inherently evil and only taught evil by both Peter's rejection and then Eddie Brock's hatred and anger, and that given a genuinely good host, it could redeem itself.
The spider is always on the hunt.
As much as I'd love Spider-MJ to stick around like I did back at Spider-Island, at this point with Silk and Spider-Gwen around, it might be a bit redundant for MJ to have spider powers. I'd love for classic Agent Venom to stay because I hate the physical changes Bendis has put him through.
