Welcome to Harry Potter Theory. Today, we’re going to be discussing the TOP 10 most POWERFUL magical Beings of the wizarding world. 
‘Being’ is one of the three classifications used by the British Ministry of Magic to distinguish the different magical creatures that inhabit the wizarding world (the others being Beast and Spirit). 
The term ‘Beings’, at least for the most part, refers to the HUMANOID (or at least, seemingly humanoid) lives of the wizarding world.
And when I say humanoid, I mean possessing typical ‘human’ characteristics- i.e 1 head, a standard number of appendages, 2 eyes etc. Although, I suppose you could argue that possession of these traits being innately ‘humanoid’ stems from a relatively human-centric point of view. There are also a few exceptions to this which you’ll see down below. 
Anyway, with that distinction made, I do want to point out that there are still quite a few ‘humanoid’ creatures in the wizarding world beyond just conventional ‘human’ witches and wizards, which is why I think that this will make for a fun list.
This list will be ranked from least to most powerful and I’ll stick to CANON to support my rationale.
Anyway, let’s dive in.
