Alien beauty and the cat

True form

The next day

"Hmm I wonder of this ladybug and chat noir are the ones with the magical energy?" Musa muttered looking at a TV store window on local news.

"You a tourist or something?" This stranger said lurking in an alley next to Musa "Cause everyone knows about Paris's super duo lady."

"You could say I'm a tourist." Musa said narrowing her eyes "Where could one go about with meeting these superheroes?"

"Ha! They only show up when a supervillain shows up or some big shot wants them to do public appearances." The stranger said chuckling.

"I see I'll have to go to them." Musa said then focused her energy in reading the strangers mind.

"girl is pretty smokin maybe I'll go easy on her taking her wallet" the strange man thought smirking while Musa frowned "Hey mam could help me with a problem in the alley?" He said taking her wrist.

"I do not think so!" Musa growled punching his face and throwing him into a door making people gasp "Do not freight people! He was just trying to rob me I got it!" Musa ensured.

"Nice moves! That was awesome!" Some woman said to Musa who just nodded and walked away.

"Now to trap the ladybug and chat noir into coming out!" Musa said making Mana stairs as she runs over buildings making a giant Mana wall over the city as she does it. After several minutes the entire city is in a giant dome causing panic "In urbe domi retinere firmamentum operiretur!" Musa chanted keeping the mana strong until she says so.

"Ahh!" Many people screamed at the giant pink dome over the city.

"Tikki!" Marinette questioned "What is that!" Her little kwami swooped to the window and gasped.

"I don't know but I think ladybug should find out!" Tikki said sharing a nod with her friend in understanding what to do.

"Tikki spots on! Yeah!" Marinette said transforming into her superhero alter ego ladybug wearing her polka dotted suit and mask she leaps out her balcony and swings away. 

"Oh no! Plagg look at that!" Adrien said looking out his bedroom window with concern but his kwami just continues to eat cheese.

"If its not cheese related I'm too busy." Plagg said yawning and curling into a ball.

"We can talk cheese later! Plagg claws out!" Adrien said sucking plagg into his ring.

"Not again!" Plagg whined being dragged into the ring unwillingly transforming Adrien into his superhero alter ego chat noir.

"Ostendit futura et flava pigtails purus vires ad minima.Ego ad virtutem potest eripere perscrutandam Top blandit." Musa said into her wrist computer recording herself again. She glides around on her back without a care smirking till something roped her waist causing her to crash to the ground "Dang ea quae nocere!" Musa snarled at her assaultant.

"Hey I recognize you!" Ladybug said the one who roped Musa up.

"Really where?" Chat noir asked not showing he knew her too.

"Uh I have my sources." Ladybug lied gracefully smirking "Your time is up Akuma!"

"Akuma? What are you talking about?" Musa asked eyes glowed white untangling herself of ladybug's yoyo "My name is Musa I am an anodite."

"Well Musa care to explain the massive dome around our city?" Chat noir asked getting into fighting position staff in hand.

"Simple give me your source of powers and I'll release your people." Musa said hands on hips.

"Not going to happen!" Ladybug said twirling her yoyo threatenly.

"Yeah what she said!" Chat noir said making ladybug roll her eyes.

"Listen power you hold has no place for humans! Give them to me willingly or I'll take them by force!" Musa said standing her ground but when they didn't budge she smirked "Well if its a fight you want then its a fight you'll get!" She said taking a step back and a strange light blinded the heroes and when it went away they gasped to see something else.

"What are you?" Ladybug and chat noir said in unison eyes wide to see Musa's skin come off leaving a womanly figure there not wearing any clothes she has black and purple skin and long waving white hair with pink illuminating around and eyes completely white.

"I've told you an anodite from the planet anodyne."Musa said her voice having a little echo to it "Not this so called akuma villain where I'll revert back to human after you destroy some object!" Musa said floating above them hands holding pink spheres "I suggest you run."
