Supersuit - She hid his supersuit, so he borrowed hers.

"Honey?" He tried to keep his voice leveled, despite the colors of his walls flashing with orange with the explosions outside. He tried again. "Where is my supersuit?"

"What?" He hears his wife calling from her room, her voice partially muffled from the increasing noise outside.

Panic beginning to set in, he turned away from the window and began pulling out drawers and pressing all the buttons and the hidden chambers in their shared space. The empty space of where his suit had gone cold and he can see bits of frost where his wife's skin may have brushed against the aluminum. "Where. Is. My. Supersuit!?"

He can practically feel the heavy hesitation in the air. "I-uh, I put it away!"

An out of control chopper spirals across Lucius' luxury windows and another explosion blankets the room in orange light. "WHERE?!"

"WHY DO YOU NEED TO KNOW?" He can see a glimpse of blond hair as they both flitted about. They were beginning to yell now, not at each other but over the increasing volume beyond the windows.

"I NEED IT!"

"NUH-UH!" Lucius can see a shadow of a bathrobe from the corner of his eyes before her frame disappeared into their bedroom. "DON'T YOU THINK ABOUT RUNNING OFF, DOING NO DARING DO! WE'VE BEEN PLANNING THIS DINNER FOR TWO MONTHS!"

"THE PUBLIC IS IN DANGER!" He yelled into the hallway, trying to put as much distance as he can between him and the windows. He ran for the closet, checking if his wife had slipped his suit into the smaller compartments between hangers.

"MY EVENING'S IN DANGER!"

Patience was a virtue he was blessed with- his father always told him. Lucius pushed the hangers aside, their clothes swaying with the accompanying door. "YOU WILL TELL ME WHERE MY SUIT IS, WOMAN!" He cried. "WE ARE TALKING ABOUT THE GREATER GOOD!"

"GREATER GOOD?!"

One of Lucius's fingers pressed on a tiny white button on the back wall of the closet and his wife's ice dress slowly emerged from the wall, untouched, unmelted and immaculate despite the disuse.

Lucius runs his fingers over the ice dress, pausing silently to feel the fine cloak between his fingers. He narrows his eyes and scoops her dress in his arms. Meanwhile his wife continues. "I AM YOUR WIFE! I'M THE GREATEST "GOOD" YOU ARE EVER GONNA GET!"

The Omnidroid collapses on its side as Bob charged into its head. Bob tucked his chin and rolled with the momentum, stopping once he saw the ground. Along with the familiar groan of the enemy robot, a familiar sound of cracking ice fills his ears.

"Frozone! YE-!" Bob's whoop of delight dies in his throat as he catches Lucius skating down a sheet of of frost in an ice dress. The slit of the dress briefly exposes his hairy legs as Frozone slows to a stop near the robot.

Violet claps both her hands over her mouth. A force-field formed around her and Dash as her cheeks reddened. Helen gaped at him then closes her mouth, her teeth clacking noisily together. Dash shrieked with muffled laughter within his sister's force-field, tears streaming down his face.

Lucius held his outstretched hand, ice forming on the Omnidroid's joints. The monstrous machine groaned and fell over. "Don't say anything." Lucius deadpanned as he slowed next to his friend.

Bob raised a gloved finger pointing at his dress. "I-Isn't that...?!"

"Do you really want to talk about this right now?"

The loud whirr caught their attention and Bob barely sidestep the robot's claw, his eyes still glued on Lucius's dress.

"Baby, I'm sorry."

"Don't."

Head in hands and mortified, Elsa shook her head. Lucius smoothed out the texture of the dress, admiring the ice's reflection from the television light. They wound up missing dinner, two months of planning down the drain and reporters managed to catch up to Frozone before he made his getaway.

The television screen split so that a picture of Lucius was on the right and she was on the left. Elsa groaned and the tips of her ears burned red as segment of Who wore it better: Frozone or the Snow Queen? began its broadcast.

Inspired by a picture of Frozone in Elsa's ice dress.

Frozen/the Incredibles AU in which Elsa is actually Frozone's unseen wife.
