Unicron's defeat

This is how Unicron's defeat goes in One Shall Rise Part 3.

Optimus Prime: Matrix of Leadership, I call upon you.

Twilight Sparkle: Magic of the Alicorn come to me.

[

Unicron: You cannot defeat me, disciple of Primus and Princess of Friendship. I have transcended physical being. By my will alone, all upon this world shall fall into chaos.

Optimus Prime: Not while we still function, Unicron. The power of the Matrix will light our darkest hour.

Twilight Sparkle: Lead you down the path of Friendship.

Unicron: NOOO!

[Optimus uses the Matrix and Twilight uses the Magic of the Alicorn on Unicron]

Unicron: Aahhhh!

[Everything returns to normal]
