This is how Umarak's sacrifice goes in
[Umarak presses a button]
Umarak the Hunter: Umarak to Autobot fleet. Return to Cybertron. That is my final command.
[The Autobot fleet heeds his call and return to Cybertron]
Quintesson Judge #1: What?
Quintesson Judge #2: The Autobot fleet is escaping.
Quintesson Judge #3: And one of the flagships is on a collision trajectory with the detonator!
Quintesson Judge #2: Direct all firepower on that flagship. Obliterate it!
[The ship remains undamaged. Inside the ship, Umarak remains in his seat even as the explosions blow chunks of the ship]
[The Quintessons watch]
Quintesson Judge #1: It's not stopping.
Quintesson Judge #2: No hero could survive that.
[We see Umarak inside the ship]
[The ship is about to blow up]
Umarak the Hunter: Until all... are... one.
[Umarak holds the throttle tightly]
[The ship collides with the detonator asteroid planet and explodes with Umarak and the Quintessons]
[The explosion makes a nova as Kuryan sheds a tear]
[The Autobot fleet flees]
[We see our heroes seeing the nova and feel sad]
Pohatu: Goodbye, old friend.
[Rudolph and Clarice cuddle as Ultra Magnus and Rodimus Prime look out to deep space]
Ultra Magnus: This nova will be his memorial.
Rodimus Prime: Guess he had seen the light.
Ryan F-Freeman: We will miss you.
[The Autobot fleet continues to return to Cybertron and an image of Umarak wipes in across the stars]
Sonic: May your heart be your guiding key.
Kuryan: Rest in piece, brother.
Narrator: But is this really the end of Umarak? Find out in tomorrow's exciting episode, Umarak's Return.
