Was inspired by the episode of MLP FiM when Princess Celestia was defeated by Queen Chrysalis.

I would say King Sendo getting defeated would not stop there because his student, Emblem, would protect this kingdom with his life.

Emblem: King Sendo!

Iron Tyrant: Wow...I didn't know I had this much power stored in me. That means this Castle is mine for the taking!

Emblem: This Castle is not yours for the taking, as long as I am around and all of the Kings soldiers, this Castle will never be yours!

Iron Tyrant: Okay Then you will fall, as your KING DID!
