My Stand Is Steve(Minecraft X Multiverse)
"Child, do you know what this is?"
Thanos raised his golden gauntlet, the six Infinity Stones shimmering with ripples of light. "With a snap of my fingers, you will turn into dust in the wind."
"Father doesn't believe it."
Fang Mo, clad in the Infinity Gauntlet, slowly shook his head, his Cosmic Sword pointing directly at Thanos's gleaming purple skull. "Today, not even the Infinity Stones, not even the Heart of the Universe can save your dog's life!"
"Do you know what this is? This is the Truth-Seeking Ball!"
Uchiha Madara stood in mid-air, laughing wildly. "It is the strongest spear, and the strongest shield; nothing can withstand its destruction!"
"You've never seen anything truly hard before..." Fang Mo grinned maliciously, pulling out a piece of bedrock. "Dare to test your skills against it!?"
"This is... the Philosopher's Stone?"
Edward stared blankly at the red crystal before him. "It can ignore the law of equivalent exchange?"
"Uh, in a sense, it can only be considered the basis of equivalent exchange."
Fang Mo touched the portable conversion table in his hand. "But if you want one, I can consider giving you a set."
When the Fourth Calamity meets the Mysterious Island mod, this blocky being finally begins to wreak havoc across the myriad worlds.
(To reiterate, the stand-in is Steve, the protagonist of Minecraft, not Captain America. This is a Minecraft story...)
(Also i am just translating this novel.)
