Is the figure really killer who killed three missing children in final secret tapes or is there unknown killer who did that but I was normally ask for who kill three missing children (as they can be seen in tapes and sound screaming can be hear)

Is mark will return to showman's the shadow with something was new and/or different but I'm not sure if he doesn't come back and his fate is unknown

What's a "origin history" I mean something was happened that animatronic were now become monster, three kids are now missing and there is unknown figure was the figure

And probably lastly, how about the figure but I think there's small known about it but can't wait for showman's the shadow release soon on 2026 or not, we'll see it
