That’s because star wars has an actual tight leash on its lore and it fucks with Disney’s marketing. SW had an “official EU” that attempts to tell some kind of story. Predator does not and every single comic, novel, and peice of media have 0 consistency with eachother (in anything thats not a direct sequel ofc) because Fox doesn’t care and signs people on to do whatever and they’re all standalone so its not like it matters. Every single AvP game are under the official AvP license and the plots, timeframes, designs, and characters aren’t even remotely consistent.
Predator and AvP have both always been a wild west free for all because they are all standalone stories with Fox’s “everything is canon” approach as none of this was meant to be a big grand coherent cinematic marvel universe. Do preds have kill glands? Do they lay eggs? Hate climate change? Harvest autism? Have rocket launchers and iron man suits? Alien dogs? Are they slavers? Are they inviting people back to their planet and dressing them in armor because they did a cool thing? Engineer nanomachines? Does eating preds give you superpowers or doesn’t it?
Its a wild west free for all and probably will be forever because this isn’t star wars tier EU to begin with and nothing has any impact on what the next writer of the month does anyways. There’s no grand plan or star wars endgame here lol. Disney doesn’t give a damn either as they’re also just wanting to do silly crossovers.
Someone made a good point about wishing Fox would differentiate “stories of aliens vs predator,” avp, and pred canon just to get something that remotely resembled a shared universe & the plot could go places beyond just being weird set peices but probably unlikely to happen.
