Beast Wars: Transformers1996

Megatron:
Now I enter these hallowed halls... a conqueror, yes. Autobots and Decepticons, still frozen in emergency stasis, awaiting a moment, four millions years hence, when they will awaken to start the Great War. Grr... the Great War. Where the Autobots defeated the Decepticons, and thus, their descendents, the Maximals, rule we Predacons. Archaic Energon-guzzlers... how dare they!

[begins to fly]

Megatron:
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... for those who made us slaves!

Megatron:
[arrives at Prime's seat] So, we are now face to face, Optimus Prime. In one future you'll become the great leader of the Autobots. But time, shall take a different track now. Computer, all available power to primary weapon.

Computer:
Weapon power to maximum.

Megatron:
[Tail weapon on right hand powers up to a full pulsing glow] 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! I unleash the storm of vengeance! Farewell!

[Megatron fires at Prime's head and light pulses out everywhere as Primal and the Maximals just enter the Ark]
