You’re all puppets… tangled in… strings!

Can you make grogar as Thanos?

i’m going to show you something beautiful everypony screaming for mercy

Radiance, a technomagological genius even at a young age, believed that the Power Ponies were too important to the world to ever quit their duty to the world. But what if one of them fell in battle? There needed to be a fail-safe. The Ponybots were planned to be this fail-safe. The first was SW33T13, whose physical template was based on Radiance when she was a filly, and an adaptive system to improve her combat abilities. Radiance doted on the young AI, who she’d planned on raising her to learn the concept of justice. But Radiance, being the creative type she was, slowly began to move onto different projects, unintentionally forgetting Sweetie, as she’d dubbed the robot. Sweetie’s processor grew bitter. Why did Radiance forget her? What made the world more important than her. So she developed her skills, slowly plotting to destroy what Radiance had ignored her for. Radiance and her Power Pony friends wouldn’t know what hit them.

“I’m going to tear you apart… from the inside”.

“You’re all puppets. Tangled in strings…strings”

It must be hard for Rarity/Radiance to have to take down her own demonic robot sister.

Oh wow, that’s a new one on me.
 
But I’d make it a tad more feminine.

@Haymaker  
Basically like this perhaps.

Works! Just need a really badass voice.

How about:
 
There are…no reins on me.

THERE ARE NO STRINGS ON ME.

Badass.

I’d originally pictured Tirek as Ultron like in this trailer mashup:

Still, this take on Sweetie Bot managed to make me laugh and cry in fear at the same time. Excellent work.

There are… no strings on me.

“Let me show you something beautiful…”

Okay, who’s the pony Pym?

Apostrophes wrong in several places!
 
‘s in this case is like saying “is”. “Mightiest hero is”? Nope. Just plain “heroes”.
 
Same with “strings” in your description. That’s “string is”.

Beautiful. And so much hype!
