My Stand-in is Steve

"Child, do you know what this is?"

Thanos raised his golden gauntlet, six Infinity Stones shimmering with dazzling light: "With a snap of my fingers, you will turn into dust in the wind."

"Dad doesn't believe it."

Fang Mo, clad in the Infinity Armor, slowly shook his head, his Universal Sword pointing directly at Thanos's shiny purple head: "Today, forget about the Infinity Stones, not even the Heart of the Universe can save your dog life!"

"Do you know what this is? This is a Truth-Seeking Orb!"

Uchiha Madara stood in mid-air, laughing wildly: "It is the strongest spear, and also the strongest shield, there is nothing it cannot destroy!"

"You really haven't seen anything hard, have you...?" Fang Mo grinned, pulling out a piece of bedrock: "Dare to compare it with this!?"

"Is this... the Philosopher's Stone?"

Edward stared blankly at the red crystal in front of 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 crafting table in his hand: "But if you want it, I could consider giving you a set."

When the Fourth Calamity meets the Mystcraft mod, this blocky person 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 an MC fanfiction...)
