I'm guessing Belos won't be part of this group when Owl House shows up.
Ah right, they'll definitely be hunting a lot of magical beings here, hopefully Rose was able to get away from them.
And that Jake wouldn't be to busy in New York.
Has he met the old version of himself from Batman Beyond or Terry?
Has he thought of using the Knightfall protocol here or is he still saving it?
The Owl House has already technically appeared. Came out in January 2020, so Luz is already in the Boiling Isles. So far , only Luz's Mom knows that she, her daughter and everyone else are fictional. The Boilimg Isles are still unaware and will proceed with the normal Canon Timeline... until Vee arrives on Earth. Then, Luz will start to suspect thing. And by the Time Luz and friends re-appear on Earth, the Owl House Plot will be about ready to wrap up.
What you should be scared of, is if Belos decides to NOT Go back to the Boiling Isles. After all, he could just latch onto some other Magical being, and then we'd bee on a wild goo-se chase to catch gim.
Rose and Jake (American Dragon, I think) are bunkering down in a safe place. And trying to get therapy.
Yes, BTAS Batman has already met his Beyond self. In fact, Both BTAS (And later on TNBA and JLU) and Beyond versions of the Gothamites are around. Timelime's got scrunched because of stuff, mainly Chrono Trigger and Majora.
Yeah, I'm Man. *beating ensues*
For a serious answer, Arkham!Bat got taken after taking out Knight Riddler. So he was 2 missions away from activating Knightfall Protocall (he still had to deal with Nora and Pyg)
