Megatron, in the name of the Pax Cybertronia and the Predacon Alliance, you are under arrest.
S2 E11The Agenda: Part 1
S2 E12The Agenda: Part 2
I served under the original Megatron. You have his name, but not his army.
Perhaps. But what does it matter if your ship is too Energon-depleted by battle to return to Cybertron?
The Maximals--
Have nothing. They were expecting rescue. I, on the other hand, have a secret store of Energon cubes, yes. Release me, and it is yours.
I think I will take it anyway.
Its location is encrypted, and my minons have fled.
Remember the defence shutdown that triggered your capture?
Yes... how did you...?
Permit me to introduce, Lt. Tarantulas of the Predacon Secret Police.
A mole, within my own organization all this time. [dryly] And I never suspected.
MMegatron (G1)
This is Megatron, leader of the Decepticons. And if you're hearing this, it means I've failed... this time. [chuckles] But I know that transwarp technology is being developed. And so I leave this message to any Decepticon descendants that may find— [message shorts out]
Decepticons forever!
S2 E13The Agenda: Part 3
[flying through the Ark] Now I enter these hallowed halls... a conqueror, yes. Autobots and Decepticons, still frozen in emergency stasis, awaiting a moment, four million years hence, when they will awaken to start the Great War. Hmm, the Great War... where the Autobots defeated the Decepticons, and thus, their descendants, the Maximals, rule we Predacons. Archaic energon-guzzlers. How dare they! [growls] Unwilling though I was to follow my namesake's instructions, it has all come down to this! The ultimate risk, for the ultimate prize! A day of reckoning with those who made us slaves!
So, we are now face to face, Optimus Prime. In one future, you awaken and become the great leader of the Autobots. But time shall take a different track now. Computer! All available power to primary weapon! [charges up his tail-based weapon]
CComputer
Weapon power to maximum.
And now, Optimus Prime, in memory of the Decepticons, for the glory of the Predacons, for the Cybertron that is rightfully ours, and mine to rule...
[as Rhinox tries to force the Ark's doors open] Come on! COME ON!
... I unleash the storm of vengeance! Farewell! [fires at Prime's head, unleashing a powerful storm of energy that spreads across the planet and into surrounding space. The Maximals are engulfed and scream in pain]
OPOptimus Prime
TIME... ITSELF... IS ALL... BEING DESTROYED!
[laughs evilly] Say goodbye to the universe, Maximals! The future has changed, yes! The Autobots lose! Evil triumphs! And you, YOU, NO LONGER EXIST!
