I mean it has been revealed that she was killed off in Agatha

So yeah sadly she died during the events of Doctor Strange 2

Death is simply a Meaningless thing in all of Comics especially for a character like Wanda (Girl has been killed like 99 Thousands times in the comics), one way or another the 616 Wanda is going to come back sooner or Later.

The More interesting character to me is I can't believe I'm saying this but actually Agatha as her character really don't do Revivals as much as Wanda does, she might actually be gone for good.

this has been discussed multiple times.

timeline book seems to indicate that she died; pilot episode of Agatha All Along seems to also indicate that.

and seemingly no contradictions after those from Marvel.

^^^ If anything, Agatha All Along is the only show so far to officially create some actual doubt towards Wanda's death, like with Agatha's "yes, no, maybe" answer to Billy's question about Wanda being alive. I'm also pretty sure I heard that the showrunners were explicitly told to refer to Wanda as "gone" rather than dead, so that's pretty telling

I swear if anyone mentions that dead body in the pilot of AAA one more time as Wanda I'm gonna screamed, that ain't her, it's either the Darkhold or most likely not even their in the first place as everything that happens during the "Crime Tv show" Part of the plot is in head of Agatha and isn't real at all.

No. Billy/Wiccan is alive and well while working with Agatha's Ghost. Tommy/Speed is also alive as we saw in the finale of Agatha All Along. Vision is alive and his whereabouts will be revealed in Vision Quest. That leaves Wanda/Scarlet Witch. There's been multiple rumors that a Scarlet Witch film is coming after the Maximoff trilogy ends on Disney+ and possibly post Secret Wars. So, I would say she's not dead yet.

Vision Quest; that Vision would be White Vision. White Vision was rebuilt from the original Vision.

Willaim; kind of ressurected when Maximoff's consciousness entered Kaplan's body.

Thomas; seemingly ressurected in Agatha All Along episode 8.

I would guess some form of ressurection for Wanda if the main universe's version ever appears again.

1. White Vis is OGVis, they are the one and the same.

2. There is no "Kind of" nor Seemingly, they were resurrected just like how in the comics the Kids Billy and Tommy were resurrected into their new bodies.

3. Again if Wanda was 100% dead then the show would have just say she was dead and buried into the sands of time just like how 616 Tony and Nat are mentioned to be Dead not "gone". Marvel is leaving a door open so that 616/199999 Wanda can come back.

What about the rumored Scarlet Witch series?

Lol even if you die there’s a chance to come back as a ghost lol @IronWidowMaikuB
