This is how Twilight vs Kylo-Tron and Kylo-Tron's death goes in The Amazing Equestria Girl Star Wars Tale.
Kylo-Tron: Why come to this place, not to simply just hide from me?
[Twilight cocks her head]
Kylo-Tron: Ah. You have a purpose. Perhaps you're protecting something.
[Twilight raises an eyebrow]
Kylo-Tron: No. Protecting someone.
[Twilight ignites her blue bladed lightsaber and charges. Kylo-Tron ignites the other half of his red double-bladed crossguard lightsaber and also charges]
[Kylo-Tron and Twilight get in a duel and Twilight wins by bisecting his double-bladed crossguard lightsaber in two while simultaneously mortally wounding him with a slashing blow to the torso]
[Kylo-Tron, shocked at being defeated so quickly, falls to the ground as his two lightsaber halfs deactivate and Twilight catches him and Kylo-Tron looks at her]
Kylo-Tron: Tell me...are you the chosen one?
Twilight Sparkle: Yes. Why?
Kylo-Tron: I always knew you had it in your heart to defeat me.
[Kylo-Tron dies as his optics return to normal black]
[As a sign of respect for him, Twilight picks him up and puts him on a display]
