The reason why, even though Banner was able to absorb the Infinity power, he couldn't save the world from the zombie apocalypse was because just absorbing the Infinity Stone energy was enough to destroy the ego of Banner, and the Infinity Hulk ego took its place.
Since Infinity Hulk was strong, and nobody was stronger than him in the present world. They couldn't even get the chance to go near the power source, much less absorb the Infinity Stone energy from Infinity Hulk.
Even if by some chance, someone defeats the Infinity Hulk, their body will be weak after the fight with the Infinity Hulk. If they absorbed Infinity Stone energy, then they would disintegrate.
Even Wanda was afraid of Infinity Hulk; that's why she raised an army of zombies as pawns to weaken Infinity Hulk and then absorb the power, or that is what Wanda had in mind.
But for Alastor, he not only defeated Infinity Hulk, but he was also in his peak state.

"Rest easy, Banner," I whispered. "Your fight's over."
Then, slowly, I raised my right hand and snapped my fingers.
A pulse of golden light erupted outward, brighter than any sun. The energy rippled across the world, stretching beyond mountains, seas, and stars themselves. Time folded, space rewrote itself, and every corrupted cell, every dead heart, began to beat again. The infection that had devoured the Earth reversed like a film running backward.
Zombies turned human. Cities rebuilt themselves. The screams faded into laughter. The bloodstained soil became green once more.
And as I stood amidst the void between realities, surrounded by the fading echoes of chaos, I smiled faintly.
If I truly wished to use the Infinity Stones' power, I could have reshaped this world into one of my own design—an empire built to worship me as their god. I could have stood above every soul, untouchable and divine. But what would be the point? I already had Nazarick. Its denizens revered me, obeyed my will, and called me lord. Another world kneeling before me would only bring silence, not satisfaction.
No, I wanted something different.
So my wish was simple: restore this world to what it once was—before the dead walked, before hope died. Let the people live their ordinary lives again. Let them forget this nightmare ever happened.
Except… not everyone.
Yelena would remember—after all, she still owed me that promise.
Kate would remember too; she had earned that much.
And as for the final touch… I made one more change.
"If I'm going to save this universe," I murmured, "I might as well make it worth something."
I focused my will, bending the energy in my hand. The stars realigned, their light flickering with a new pattern.
"I wish to make this universe… the Marvel Cinematic Universe."
The moment the words left my lips, everything fractured.
The battlefield vanished. The world peeled away like burning parchment, dissolving into light. I found myself standing in an endless void—empty, silent, infinite. Only Shalltear stood beside me, her silver hair glowing faintly in the white expanse.
"Master…" she said softly, glancing around. "What did you do this time?"
Before I could answer, the familiar hum of the system echoed in my head, followed by a cascade of bright blue screens materializing in front of me.

The blue screens shimmered, reconfiguring themselves as the system calculated. A progress bar filled at an agonizing pace.
Shalltear floated closer, peering curiously. "My Lord..."
Then the screen flickered again, displaying a final message.

I stared at the prompt in silence, my reflection shimmering in the holographic display.
