Often, they show survivors as being tough and resourceful. For example, in 'The Walking Dead', the characters have to find food, shelter, and weapons while constantly on the lookout for zombies. They also have to deal with other groups of survivors, which can be just as dangerous.
The members of Team JNPR could also be likely survivors. Jaune has grown a lot in his skills. His leadership and swordsmanship could be useful. Pyrrha, if she were still alive in this fanfic scenario, would be a great asset with her combat abilities. Ren's calm and collected nature, along with his stealth and combat skills, would help him survive. And Nora, as mentioned before, would be a great addition to the group of survivors. They could work together with Team RWBY to face the zombie apocalypse.
Well, in the comics, Terminus is bad. It's a place where chaos and evil prevail. The story shows how it poses a significant threat to the main characters.
Definitely Harry Potter himself. He has faced so many dark and dangerous things already, so he'd be able to handle zombies. Hermione would also be a likely survivor. Her vast knowledge of magic and quick thinking would serve her well. And Neville Longbottom. He has shown great courage and has a deep understanding of Herbology, which could be useful in creating defenses or finding antidotes.
Well, Rick escapes Terminus through a combination of strategic planning and unexpected allies. He figures out the weaknesses of the place and makes a daring escape with the help of some characters who have their own reasons to join him.
