A/N: To the two people who voted for a Miraculous crossover on my poll, this is for you. I'm sorry it took me so long to get inspired for this and post it. But here it is! Miraculous/Avatar! (The name is open to change, though, if you have any suggestions.)

Disclaimer: I own no characters. The interactions, however...maybe.

TIKKI

"Now, Katara, I kno-"

"HOW DO YOU KNOW MY NAME?" Katara freaks out. "WHAT EVEN ARE YOU?"

"I'm Tikki!" the bug-mouse says. "I'm a kwami. Your kwami!"

Katara pauses in the middle of her waterbending form, letting the water fall back into the river. "My...What's a kwami?"

Tikki smiles at her. "A kwami is like a god, but bound to something specific. I'm the kwami of creation, bound to these earrings." She holds out two beautiful red-and-black earrings in her tiny paws.

Katara pokes them. "What am I supposed to do with them?"

"Wear them!"

"...and?" Katara knows these things never come without a price.

"Then you'll be Ladybug! You'll have the powers of Lucky Charm, creating one object that is whatever you need at the moment, and Miraculous Ladybug, which fixes things! But after you use Lucky Charm you have five minutes before you transform back and I'll need to eat."

Katara smiles. "That does sound pretty cool," she admits, reaching for the earrings.

Tikki helps her fasten them into her ears. "Now, to transform, all you do is say, 'Tikki, spots on!' Try it now! You say 'Tikki, spots off' to detransform."

"Tikki, spots on?" Katara tries.

Tikki vanishes, and during what seems to be about five minutes but is probably actually five seconds, a black-spotted red mask appears on Katara's face, black-spotted red running down her arms and legs, with blue-black gloves and boots. Her hair, as well, gets red streaks, her hair loops turning blue-black...since when can she feel her hair color? Or know the color of things she can't see?

Katara runs to the river and looks at her reflection. Sure enough, she looks exactly like she imagined.

"I'm beautiful," she breathes. "Thank you, Tikki!"

Tikki doesn't answer.

Katara grins at her reflection. Then a thought strikes her. She goes through a form, and the water obeys her like it should.

She has her (extremely powerful) bending. She has magical creation powers. She has a bug-mouse god on her side.

The Fire Lord doesn't stand a chance.

A/N: I spent awhile thinking up which kwamis go with which Avatar characters, and what their costumes would be. The first7 chapters are going to be pretty short, but then we'll get into the action!
