If Buffy the Vampire Slayer (TV series) and her friends were in the Walking Dead Universe, could they survive and thrive in the universe? The Walking Dead-verse is the opponent

Most who would wins is based on person a vs person b, but I had a thought of putting someone very OP and powerful in one universe against an entire universe made to drive people to insanity, self-destruction, and other horrible ends.

Buffy the Vampire Slayer and friends has left Sunnydale and entered a portal that sends her to the Walking Dead Universe filled with zombies. She does her obligatory hero thing and kills some zombies, easy. She meets up with various people and adds to her friends group, but over time, her old and new friends die and she starts getting into Season 6 levels of depression.

The Walking Dead universe is tragic, filled with poignant and pointless deaths, plus no one is ever safe or happy. It might seem fun at first, but it is a terrifying opponent to survive and thrive agaisnt.
