A random Akuma was attacking everything when Marinette, in her Miraculous Ladybug persona, came in. "Hahaha! Beware all citizens of Paris, I, the Tidal Destruction, will be the end of you all!" shouted the akuma as they got ready to murder some children.
However, Marinette soon came to the scene and saved the children while simultaneously making the akuma's hand explode into pieces. "Who dares interrupt my attack?!" hissed Tidal Destruction.
Marinette released the children and crossed her arms as she gave the Akuma a determined glare. "A girl who's a ladybug for fun."
...
"Your ridiculous and stupidly short backstory is a disgrace to herokind!" growled Tidal Destruction as they got ready to attack Marinette with their remaining hand. "Prepare to die!"
Literally a second later, Marinette punched the original person that was Tidal Destruction out of their akuma form and jumped out of the scene as a nearby Adrien could only ask, "Who is that Marinette?"
