While I got a bit of time I'll just post some spoilers for those interested. Still a B+.
Spoiler
For those curious, it is indeed a sequel to Archie Versus Predator. It picks up a short while after the events of the first series with the Predator of that story having been converted into the new Archie (he still acts like the Predator of that series though and still speaks as he did in emojis). They all try to leave but there's a joke about the Mark Waid Archie book with it leaving them wondering if they're cancelled and given the original was a limited series I'm not sure how that makes sense..., or is Predator supposed to be canon to Archie? Granted some of the show's cast want Predator on Riverdale and I don't blame them but that's besides the point.
Eventually they end up in reboot Riverdale with a brand new cast to kill off and Dilton (I think?) has a Predator mask which somehow gets the attention of the other Predators. I'm not sure if it's native to this continuity or if it's supposed to belong to PredArchie but considering they comment about PredArchie not wanting to go home and the others find out through the helmet, it seems he doesn't want these guys to know he's here. It's also mentioned that PredArchie's transformation is temporary and that he'll eventually turn back into his normal self
Overall a lot of this is setup but considering that we have a fresh new Riverdale cast (including an Archie, Betty, and Veronica) I feel like this could've been it's own thing. But then again it is the first issue and it's setting the stage so I'm not as worried about it. As an aside, PredArchie is also indifferent towards "cancellation" which is somewhat funny considering despite The Predator's reception the franchise got this, two video games coming, and a series of toys. I can understand why he'd feel indifferent towards it. There's also a oke about the other Betty mistaking the Predator helmet for a Phasma mask. I'm not 100% sure if that's a joke about Disney owning Fox so they can make that joke now but I like it. All the other Predators however are modeled on the Assassin Predator, they just walk plantigrade and some have helmets. I feel like they should be modeled more on Fugitive considering Assassin was a one off. However as much of a distraction as it is, it's fine.
