ideas for time-eating Fate?

i am currently running a wild west motw game (with the IMPS team playbook) for some friends.

one of my players leveled up last session and decided to take the Chosen’s I’m Here For A Reason move. we picked her fate tags (Visions, Sacrifice and No normal life, The end of days) and talked briefly about what the character is here for.

the character already has past lives (established by the Searcher’s background, a secret to the character), so she stated she liked the idea of having multiple reincarnations who have to defeat some very powerful evil (destroying dimensions/time powerful).

i asked for any particular style or vibe and she only expressed that she wanted to be surprised by it and discover it over the course of the game. i’m glad she has so much faith in me, but eek! i am drawing a total blank on a monster that could be reincarnated and needs to be destroyed relatively soon. i run into an additional problem where i’ve run for this friend often, so id want to avoid snake monsters, eldritch monsters, and demons because of previous games.

i’m sure a few days of research will yield something, but i wanted to see if the collective could come up with anything! thank you for reading, happy holidays!
