[Context: The devastated battlefield stretches with rubble and smoke everywhere. The smoke curls around the towering figures of the two ancient warrior titans. Optimus Prime, leader of the Autobots, versus Megatron, leader of the Decepticons. The noise of battle (clashing metal, explosions) resonates, but the epicenter of the conflict is the personal confrontation of the two ancient warriors.]

Megatron:Looks at Optimus, his red optics glowing with dark resignation.

—"We were once brothers." He says, his deep, resonant voice heavy with a cynical and melancholic tone. Megatron holds Optimus immobilized with a giant hand on his chest, holding him to the ground.

Optimus Prime:Looks at Megatron, his blue optics glowing with seriousness and suppressed pain.

—"Once... In the past." He says, his voice deep, husky, and heavy with finality. Optimus brings his left hand to his right chest, feeling the weight of his memories. With a determined movement, he reaches under his armor. Megatron watches with a newly calculated suspicion of what Optimus is doing. His mind spins, wondering what hidden weapon, what last-minute trick he could be pulling.

Suddenly, Optimus pulls out a small, shiny, red-colored metal box and opens it, revealing a shining gold ring (or a fragment of high-purity Energon embedded in it). Optimus, with a sudden effort, stands up, pushing Megatron's hand away from his chest.

Optimus Prime:Looks at Megatron, his optics now shining with radiant determination.

—"¡Marry me, Megatron! From now on, we're family!." He says, in a firm and powerful voice, his tone absolutely serious, but filled with unusual joy. Optimus smiles happily, a rare gesture in the midst of war. While Megatron looks at him, completely confused and paralyzed. His metallic face blushes slightly (a faint red pulse is visible on his faceplate) at the unexpected and absurd proposal.

With a swift and unexpected movement, Optimus removes Megatron's right hand from around his neck (where he had pinned him) and takes his clawed left hand. He places the ring on one of Megatron's fingers.

Optimus Prime:Looks at Megatron, with disarming sincerity.

—"¡You're handsome!." He says, his voice soft yet deep, his tone filled with genuine affection. Megatron blinks, stunned and overwhelmed. The roar of battle seems to silence at that precise moment as the two former friends, now newly engaged, stare at each other through the smoke.

Optimus waits for a response from Megatron.

[It could be the Alpha or the Omega].
