So what IS Mary Poppins?

I’ve seen the musical play and the movie, but I’ve never read the books. Is it ever revealed what sort of being Mary Poppins is?

She obviously has powers, but is far from omnipotent, so I’d assume she’s some kind of witch. OTOH, she blends in perfectly with humans and seems to relate to them. Is it discussed where she came from (a Hogsmeade type place, perhaps)? Or if Bert is what she is?

Straight answer or conjecture welcome.

She’s a witch. Burn her!

The internet consensus seems to be Time Lord.

She’s a nanny.

Exactly. She’s Mary Poppins. No further explanation is needed or offered.

NILF.

My theory is that she’s a dream, escaped from Oneiros’s realm during his century long absence.

I’m gonna go with Time Lord too, especially given the new “Missy” character in the latest series.

Practically perfect in every way.

I don’t believe P.L. Travers saw fit to explicate her origins very much. I believe at one point one of the magical creatures they meet addresses her as a daughter of the Sun although whether that was meant to be literal or not is not clear.

As it is, you can make up pretty much any origin you like for her as there’s very little official canon to contradict you.

If we’re going to go with ‘Standard TV Tropes Insane Speculation’, ‘an incarnation of Haruhi Suzumiya’ fits her far better than ‘Time Lord’.

Beat me to it, QuickSilver.

She’s someone there to save Mr. Banks, according the P.L. Travers in the Saving Mr. Banks movie about the making of Disney’s Mary Poppins.

You don’t want to know. (shudder) You really don’t want to know…

the Green Hornet was descended from the Lone Ranger. both strong hero of different nature.

if you go deep into the original writings of Mary Poppins you will find she descended from Xena.

And how do you know she’s a witch?

Mr. Banks’ ex-wife in drag.

Sounds like this calls for a rebooted, gritty origin story.

The local 'shroom dealer. Uses the nanny business as a front. Doses up the brats to make them easier to handle and so they won’t rat her out.

Bert is one of her regular customers. His brain is so fried he thinks he’s a Cockney instead of an American.

She turned me into a newt.
