The wind blew gently across the rooftop as Izuku Midoriya stood at the edge, staring down at the streets far below. His heart was heavy with the weight of Bakugou's words, which echoed in his mind like a cruel taunt.

"Go take a swan dive off the roof and pray you're born with a quirk in your next life!"

Tears welled up in Deku's eyes, blurring his vision as he looked at the pavement below. He had always dreamed of being a hero, but those dreams had been shattered time and time again. Now, with no hope left he took a step forward, closing his eyes as he prepared to plunge into the darkness.

But instead of the cold embrace of the ground, Deku felt himself being pulled into an abyss. The sensation was disorienting and when he opened his eyes, he found himself standing in a vast, dark expanse. Shadows writhed and shifted around him and in the distance a towering figure clad in ancient, menacing armor approached.

"So, a soul has wandered into my domain. How intriguing..." The voice was deep and resonant, filled with malevolent power that made Deku's knees weak.

Deku stumbled back, his eyes wide with fear and awe as the imposing figure drew nearer. "W-Where am I? Who... who are you?"

The armored giant adorned in dark, gothic plate armor stopped before him, his glowing green eyes glowing through the slits of his helm. "I am Mordekaiser, the Iron Revenant. You have been brought here by your own despair. I see potential in you, boy." in his cold and merciless tone with commanding presence. 

Deku looked down at his trembling hands then back at the fearsome being before him . "Potential? But... I'm quirkless. How can someone like me have potential?"

Mordekaiser chuckled, a sound that reverberated through the void lace with echoing effect. "Quirks are but fleeting sparks. True power comes from within. I shall grant you a fraction of my strength and in return you will become my vessel in your world."

Deku hesitated, the weight of the decision pressing down on him. He recalled Bakugou's cruel words, the hopelessness that had led him to this dark place. But he also remembered his dream in hopes of becoming a hero who could save others.

"If it means I can make a difference... if it means I can stand up for myself and others... I'll accept your power" Deku finally said, his voice trembling but resolute.

Mordekaiser's eyes gleamed with approval. "Very well. Embrace the darkness, and rise as a harbinger of doom."

The air around Deku thickened with an oppressive weight as the dark energy surged into him, tendrils of power winding through his veins like serpents. Each breath became a struggle, the oxygen in his lungs replaced by the suffocating force that was invading his body. He gasped, desperate for air, but it was as if the very atmosphere had turned against him, pressing inwards constricting his chest.

His muscles seized, locking in place as the power flowed through him, burning with an intensity that threatened to consume him whole. His vision blurred, darkness creeping in at the edges, but the energy kept coming, relentless and unyielding. It felt as if he was drowning in it, the weight of it pressing down on him, crushing him from the inside out.

The void around him trembled, the dark energy bending to his will and then with a sudden, violent lurch it began to collapse, pulling him back toward the world he had left behind. But he was no longer the same. The power had reshaped him, twisted him and now as he returned, there was no mistaking the presence of Mordekaiser in his soul.
