Keroker

After Roxas, the lunar guard had borne a litter of three puppies, she was heartbroken when only one out of the three survived. However, over time she and the rest of the pack began to notice small changes in one of the pups.
it turns out a member of the Faelcu had attempted to swap Roxas' children with its own, and those two other Faelcu pups died due to unforeseen circumstances. Keroker, on the other hand, managed to survive, and he, alongside his pack, were mostly none the wiser to the change, except for the pack leader, Pandemonium. After encountering the aftereffects of the Faelcu on other neighboring packs, she starts to grow suspicious of Keroker, believing him to be the beginning of other wolves going missing, even though over the history of the Troublemaker pack, wolves did tend to go missing, but that was attributed to the Dark; a pack of wolves born from the shadow casted by the dark side of the moon, led by Kurai.
