The Avengers were gathered in the meeting room of Stark Tower — Tony flipping through holographic reports, Natasha quietly sipping coffee, and Steve trying to keep the peace, as usual. Thor sat proudly at the table, telling an overly loud story about his latest “glorious” battle.

That’s when the doors burst open with a loud crack of thunder.

Everyone turned. Standing there, eyes blazing like a summer storm, was a young woman clad in Asgardian armor — lightning still flickering around her fingertips.

“Thor Odinson!” she bellowed.

Tony raised an eyebrow. “Okay, definitely related.”

Thor blinked, his grin faltering. “Ah… sister! What a most unexpected— and slightly alarming— surprise!”

“Unexpected?” she snapped, marching toward him. “You borrowed my enchanted cloak for ‘a few hours’— three months ago!”

Bruce muttered, “This should be good.”

Thor laughed nervously. “Ah, yes, the cloak! A fine garment, indeed. I merely— misplaced it during battle.”

Her eyes narrowed. “You traded it for ale in Nidavellir, didn’t you?”

The silence that followed was deafening. Tony tried — and failed — not to laugh. “Classic sibling move.”

Before Thor could respond, lightning flashed through the windows, shaking the table. “You’re cleaning this up, brother,” she growled, “or I’ll show these mortals what real thunder sounds like.”

Steve leaned toward Tony and whispered, “Remind me never to make her angry.”

Tony grinned. “Too late. I already like her.”

Thor sighed, slumping in his chair. “It seems the storm has come for me.”

And as thunder rolled outside, even the God of Thunder knew — this time, he wasn’t the most dangerous one in the room.
