To add in the context of my FoE au, its 20 years after the first FoE story, in this case, some of the raiders are also called ravengers, while some are called old raiders.
Bonehead - What’s even more morbid than ravengers using skeletons as props to immediate enemies, a literal bone armor worn by a crazy pony.
Bonehead found out that sometimes bone armor can resist some damage, and can be used for immadation. As for the cutie mark, he earned that when managing to use the skeleton from a dead pony. The side effects: Sometimes he cannot wear unicorn skulls due to the horn being there, and no wing bones due to not having wings himself.
There is a WIP Rainbow01 au variant of him as well
