A classification is given by the Department for the Regulation and Control of Magical Creatures to all known Beasts, Beings and Spirits. These offer an at-a-glance guide to the perceived dangerousness of a creature. There are five categories.
The Five CategoriesEdit
- XXXXX: Known wizard killer / impossible to train or domesticate.
- XXXX: Dangerous / requires specialist knowledge / skilled wizard may handle.
- XXX: Competent wizards should cope.
- XX: Harmless / may be domesticated.
- X: Boring.
Behind the scenesEdit
- In Fantastic Beasts and Where to Find Them, Ron Weasley adds nine "X" to Acromantula's Classification. This is a reference to Ron's fear of spiders. This may also be contributed to by Aragog's offspring almost killing them, only being saved by the chance appearance of his father's car.
- Despite the Basilisk being a XXXXX-ranked creature, meaning they are impossible to be domesticated, Parselmouths are able to control them. This is likely due instead to the incredibly dangerous nature of the creatures.
