This is how Orion and Nightfall rebel goes in Orion Pax and Nightfall Twinkle Part 3.
Vehicon #1: No one told you to stop, Pax and Twinkle.
[The Vehicons point their blasters at Orion and Nightfall]
Orion Pax: We believe Megatron intends to use whatever he finds on Project Iacon to harm the Autobots and Ponies.
Nightfall Twinkle: Please. We can warn them.
[The Vehicons start beating them]
Vehicon #2: You have to admit, it's a privilege to stomp a former leader of the Autobots and a former Princess of Friendship.
Orion Pax: No, please stop.
Nightfall Twinkle: Enough!
[Suddenly, Orion brings out his cannons and Nightfall's horn starts to glow]
Orion Pax: I'm... I'm armed?
Nightfall Twinkle: And I have magic?
[The Vehicons look at each other then fire at Orion and Nightfall but they fire back and kill both Vehicons.]
