A brave male warrior and a beautiful maiden from his village could be the main characters.
The main characters could be an older, experienced warrior and a young healer. The warrior gets injured often in battles and the healer takes care of him. Over time, they develop feelings for each other. The story could explore how their different roles in the community - one as a fighter and the other as a healer - influence their relationship.
Perhaps it could be two warriors from rival clans. They start off hating each other because of their clans' enmity, but as they interact more during battles or truces, they fall in love. So the two main characters would be these two warriors from different sides.
There could be a brooding leader, perhaps named Darius. He has a tragic past that led him to embrace the dark powers. Another main character might be a female warrior, like Lyra, who is skilled in stealth and has a special ability to manipulate shadows.
I don't know for sure who the main characters are in the 'time warriors story' since I don't have the details of that specific story. But they could be brave and strong - willed individuals.
Ganondorf from Hyrule Warriors could be a very interesting main character in this fanfic. His villainous nature could create a lot of conflict in the MLP world. On the pony side, Fluttershy could be a main character. The contrast between her gentle nature and Ganondorf's evil would be quite fascinating. And perhaps a character like Midna from Hyrule Warriors could also play a major role, using her unique abilities in the MLP world.
I'm not sure exactly who the main characters are without reading the novel. But they could be Feral Warriors, perhaps a strong and fearless male warrior and a female character who catches his eye.
