Blackbeards Role in The Final War (1138 spoilers)

I think Blackbeard will steal Imus devil fruit in the final war same way he did to Whitebeard. I don't have much evidence, except that Oda parallels pre ts and post ts arcs, and that a Teach adjacent figure is missing in the mural. If we go by the arc parallel idea, than that would mean Elbaf is Amazon Lily, making the next arc Impel Down. I don't think well get a full fledged Impel Down II, but rather something like the Koby chapters in Egghead, or god-forbid an SBS question. Regardless, what would happen is Teach goes to Impel Down, frees doffy, weevil, bonclay, and some randoms then goes to Marejois or wherever the final war happens. He then third-parties everyone again steals the devil devil or dragon dragon or whatever fruit Imu has, then kills Garp or something, and says he's gonna claim One Piece. This could also explain why Teach isn't in the mural, he is he's the final boss and Imu is represented by the dragon on the tree.

tldr; blackbeards gets a zoan theory never ends
