Snake Mother

This is how The Storm King steals the Alicorn magic goes in Crash's, Thomas', and Ryan's Adventures of My Little Pony: The Movie (2017).

Twivine Sparkle: It's time, Your life-force will be released Father from his prison and He, the Storm King, and I will rule Equestria! You will be nothing but a princess.

Twilight Sparkle: [weakly] You won't get away with this.

Twilight Sparkle: Tempest, don't do this. Don't give the Storm King—

Tempest Shadow: Your magic? Did you think you'd keep it all to yourself? Time to share. I'd love for everybody out there to know what I can really do.

[

The Storm King: Ooh, fascinating! What can you really do? [

Grubber: Your bidding, of courth, Your Mighty One.

[

[

The Storm King: Bidding's good. I like bidding! [ ] Um, what are you supposed to be?

Twilight Sparkle: I'm the Princess of Friendship!

The Storm King: [laughs] Oh. That's nice. [to Tempest] Why are all these princesses still moving?

Tempest Shadow:

The Storm King: Yeah. So, speaking of problems, this place, it seems a little too—oh, I don't know—cute!!! I don't like cute! I never did like cute! Doesn't really go with my whole "big bad powerful magic guy" thing, does it?! Deliver the punchline, Tempest, because this has gotta be a joke! [grunts]

[

The Storm King: Huh? [gasps]

[She opens the Mallet Duck's head and founds a Key]

Twivine Sparkle: Yes, I search for centuries!

[She puts a Key into the hole, draining Twilight's Life-force and Magic]

Twilight Sparkle: [struggling] No!

The Storm King: [laughs] Check out the light show! Wow! Wow!

[

[

[

Twilight Sparkle: [gasps]

The Storm King: Let's get this storm started! Ooh, hey, that's good. I should trademark that.

[

[

Twilight Sparkle: [yelps]

[

The Storm King: Not bad. Actually, kinda first rate. What else does it do?
