In the future...
Peter panted for air - he felt his muscles ache, and his ears ring. He was unable to feel his surroundings, nor pay attention to the battle raging around him. He had just fought with a threat that few could have even predicted. That few could have even imagined before. The fact that he hadn't died yet surprised him.
The son of Princess Celestia, Thor, valiantly used his hammer, forged by the Sun itself - swinging it, and casting arcs of electricity. Thunder struck the foes - the myriads of hostile ponies, humans, and other creatures that believed in the cause of a mad, mad being.
The son of the Element of Generosity, Tony - felt his suit wearing down. It had its limits. Whatever functions he was able to perform were now hindered by a partially broken power source. Not even the ingenuity he received from his mother could be of much use. His arms produced beams of power to strike right through a massive beast that attempted to destroy him.
The son of the Element of Kindness was, at the moment, anything but the representation of that Element's offspring. He was now a massive beast that only partially resembled that of a human - with muscles that reached such impossible sizes that it was truly a miracle of either science, or magic - whichever granted Bruce this boon from birth. He pummeled at the waves of foes - his thoughts only of the protection of his family and country. Perhaps from this, he could associate it with kindness.
The son of the Element of Loyalty on the other hand, was a more straightforward example. Steve used a special shield - one decorated into the colors of the Equestrian flag and their symbol - the two circling Alicorns. His connection to the half-magic, half-scientific shield, made out of a rare material, had allowed him to use it as an efficient throwing disk, splitting foe after foe with ease, before returning into his hand magnetically.
The son of the Element of Honesty, Bucky was his comrade. One could confuse him for being an ordinary human - but with a metal arm, and a magically enhanced firearm, he was able to both beat and fire at his opponents with intense precision and lethality. The arm was a feat of ingenuity and allowed for many features - with many weapons hidden inside, such as a flamethrower, and miniature rockets that tore through the enemy.
The son of the Element of Laughter learned much from his mother - the idea of valuing and cherishing life and his friends made his bow fire true. He pulled back the string and shot the various arrows - learning also from his mother how to utilize various tricks and tools into his arrows. It only took a bowstring, and a single arrow for him to defeat a myriad of foes with just one shot of a special high-pressure, explosive arrow.
The daughters of Princess Cadance and Captain Shining Armor, both armed with immense agility, and a pair of firearms each, all used their immense dexterity, and skill to gun down, and fight through them with their knowledge of martial arts - working together to synergize. Though one was older than the other, they each trained often, and were united through the effort.
And of course, there was the son of Discord - a mysterious man who produced magic from his very hands that could commit unbelievable, wonderful feats of chaos magic. To describe his actions would require an entire story of his own - for who better to cast volatile magic and use the power of the unpredictable than the very son of the Draconequus God?
The battle had been ongoing for hours. No victor seemed to be in sight.
And none saw that their foe - the Titan of Death, was close to the power that would ensure his victory once and for all.
Except, Peter was closer to it.
Peter panted for air - he felt his muscles ache, and his ears ring. He was unable to feel his surroundings, nor pay attention to the battle raging around him. The fact he hadn't died yet surprised him.
Though perhaps, this surprise was only temporary. There was no guarantee he could survive this. No guarantee that what he was about to do would even leave a single of his atoms standing.
But if he does not act here and now, there was indeed the possibility that it would all be over.
The injury meant nothing. The pain meant nothing. It did not distract him. It did not distract him from his goal. Not even the sound of his mother yelling out for him.
As Peter looked at the tool of immense change and power that sat on his very knuckles, as he stared down at the colors that each represented unthinkable forces that controlled the very life itself - and the Infinity beyond it...
He wondered, deep in thought. Past the terrible injury that quickly sapped him of his strength and blood...
"How did it come to this...?"
