These are a family of wolves that got lured into a lab with food and forcibly injected with spider DNA as an experiment. This made them mutate into having 8 eyes and legs, venomous fangs, and the ability to create silk and stick onto surfaces with their paws. They escaped that abusive environment and now live in a cave within the forest. However, despite now being free, Luna (the mother) still feels resentment against the entire human race and refuses to trust them again.
