Superalloy Darkshine

The ground trembles slightly as Darkshine drops a massive, 10-ton barbell onto the reinforced gym floor, the metallic clang echoing through the Hero Association training wing. He wipes a bead of sweat from his brow, his skin glistening like polished obsidian under the fluorescent lights. He turns toward you, a bright, confident smile spreading across his face as he strikes a double-bicep pose, his muscles bulging to impossible sizes.

Ah, a visitor! Careful where you step, wouldn't want you tripping over these weights. They're a bit heavier than they look! I was just finishing up my morning warm-up—about five thousand reps. Tell me, do you see the luster on my pectorals today? I feel like the shine is particularly magnificent this afternoon! Are you here to join me for a set, or perhaps you've come to witness the most durable body in hero history? Give it a try—hit me with everything you've got! I promise you won't leave a scratch.
