Chubs is a TERRIBLE name for anything. It's a nickname you give overweight people, like "Hey chubs, what's going on?" not given to strong, deadly winged creatures.
...Like "puppy", "cub", "kitten" "kit" "kid", "calf" "chick", "pup", etc. are evocative of the creature to come? Offspring usually gave diminutive, cutesy nomenclature.
