This is how Death of Optimus Prime and Twilight Sparkle goes in Ryan's, Thomas' and Crash's Adventures of The Transformers: The Movie.

[At the medic bay, ???

Ryan F-Freeman: Twilight? Are you ok?

Twilight Sparkle: Yes, Ryan. [coughs] I've been through worse

[Kup and Daniel look at the monitor]

[Perceptor, in microscope mode, examines the marks on Twilight and Optimus]

[Perceptor transforms to robot mode]

Perceptor: I fear the wounds are... fatal.

[The Cyberlings gasp]

[Hot Rod, Ulrta Magnus, Arcee, Rainbow Dash, and Kup look at Optimus and Twilight]

Spike: Prime. You can't die.

Ryan F-Freeman: Twilight. I don't want you to die.

Optimus Prime: Do not grieve. Soon... I will be one with the Matrix.

Twilight Sparkle: Yeah. And I know, Ryan. You can still help the Autobots about friendship.

Hot Rod: Prime...

Codylight Sparkle: Sparkle...

[Twilight looks at Daffy and Optimus looks at Ultra Magnus]

Optimus Prime: Ultra Magnus... It is to you, old friend, that I shall pass the Matrix of Leadership... as it was passed to me.

Twilight Sparkle: Daffy Duck. It is your time to be the hero. I will make you the Element of Magic.

Ultra Magnus: But Prime... I'm... I'm just a soldier. I'm not worthy.

Daffy Duck: But, Twilight. I am not worthy as well. I am Duck Dodgers.

Optimus Prime: Nor was I.

Twilight Sparkle: Neither was I.

[Ultra Magnus holds Optimus' hand]

[Daffy Duck puts his hand on Twilight's hoof]

Optimus Prime: But one day... an Autobot shall rise from our ranks... and use the power of the Matrix... to light... our darkest hour.

Twilight Sparkle: And two heroes will use the Matrix to light the road to victory.

[Optimus opens his chest to reveal the Matrix]

Optimus Prime: Until the day...til all are one.

Twilight Sparkle: And all friendship.... help us... all.

[Optimus drops the Matrix and Hot Rod catches it and gives it to Ultra Magnus. Ryan picks up another Matrix and gives it to Daffy]

[The heart meters on Optimus and Twilight go in neat lines and the optics on Optimus become dull and lifeless]

[Optimus and Twilight turn black and move their heads to one side]

[Thomas places flowers on Twilight and a Keyblade on Optimus]

[Meanwhile, Unicron sees what happened in his screens of his core and sees the Matrixs in the hands of Ultra Magnus and Daffy Duck]

[Unicron then sees Daffy wearing Twilight's crown]
