Prompt by @demigodseameg16
Going off of the Maribat Salt, and being a lover of the Teen Titans (The 2005 anime show) I propose this prompt.
In Starfire's lore, she has a missing little brother named Wildfire, who was sold into slavery as a baby and disappeared.
What if instead of creating a sentimonster, the Agrestes, who had knowledge about...the other side, actually bought Wildfire as a child and used the peacock miraculous to hide his powers, causing it to break like in canon.
So Adrien is actually Tamaranian, and Starfire's long lost little brother.
We end up in the present where Ladybug has finally decided to contact the Teen Titans as she believes her "Miraculous Team" could be great allies to the Titans, and be the start of the "Titans Paris". She is wanting to dispose of Chat since as guardian, she knows that the Titans are on a next level, and Chat, in her mind, isn't it. Good minions don't question her orders, and Chat has been questioning her a lot lately (in reality, it was his idea early in the beginning to ask for the Titan's help out of genuine need, but Ladybug is using it now to prove herself to a wider audience and gain more glory.)
So imagine her shock when the Teen Titans answer her call, only for Starfire to immediately clock Chat as not only a fellow Tamaranian, but her long lost brother?! Her Intel said nothing about a brother?!? Now the Teen Titans are agreeing to train her team, but it's only because of this stupid cat!! Apparently, he's now the go-to between the Teen Titans, and because of his "stupid new powers", which are his dormant Tamaranian powers being awakened after Raven broke the spell, he gets extra training from all of them?! It's not fair! This was supposed to be about her! Whatever, at least she has a new good reason to take away his ring, he can keep his stupid alien powers, she'll just find a BETTER black cat, like her beloved Adrien.
Only, Plagg isn't leaving. See, the Tamaranians worshipped a cat god as their creator. Plagg wasn't just a kwami, he is pretty fond of the Tamaranian race for a reason. Finding out his kitten is one of his own? Oh, there ain't no way he's leaving now. And for Marinette, Every time she tries to get near Adrien, this weird girl named "Kori" steps in and blocks her, apparently she's Adrien's new bodyguard? That's clearly a front for a crazed stalker fan trying to take her away from him! I mean, Kori's friends, "Victor", "Rachel", "Garfield" and "Richard" are CLEARLY bad influences on Adrien, always sneaking him out to hang, probably to do who knows what! It's like the universe is against her!
Of course it would be very bad on the Teen Titans part to not do their due diligence and research fully into Adrien Agreste, and finding out about his background, have humanoid covers to help blend him to rescue him from an obviously abusive household, and finding out that Adrien is Chat Noir? Well, Ladybug may have her own plans, but the Teen Titans are the ones you call when there's trouble. And from the war on the horizon, they are definitely gonna be staying for a while.
Some fun tidbits would be seeing how Chat Noir's powers and Adrien's powers start to blend together, which is why he needs training from both Starfire and Raven.
Chat Noir also gets training from Beast Boy regarding his heightened animal instincts
No Class Salt, but only a few of the class/heroes are keyed in on the Teen Titans true Plan, which cements them as becoming the Titans of Paris. Cyborg trains Alya and Max (both high intellectuals prone to technology). Raven trains Juleka and Luka (empath powers align with her strengths, helping Luka focus his heart song ability and teaches Juleka about her own abilities.) Robin trains Kagami and Nino (Kagami being a martial artist and world class fencer isn't lost on him, but there is always more to learn, and Nino wants to learn both offensive and protective styles of fighting.)
Ships aren't the main priority, but within the Teen Titans it's Starfire/Robin and Raven/Beast Boy. No ships with Adrien as this is focused about him discovering who he truly is and the found family aspect.
Long term ending is the Teen Titans and co defeating Hawkmoth and finding the broken peacock miraculous, which Raven fixes with her magic, seeing as she has the answer in her Grimoire, and setting up the Titans Paris, with Kagami and Nino being team leaders, and Adrien moving with the og Teen Titans to be with his sister, and taking the miraculous box with him as the new guardian (who better to watch over a bunch of godly aliens than an alien himself?) Short term ending is everything with Marinette/Ladybug coming to light, Marinette losing the Ladybug earrings and having her guardianship revoked. The new Ladybug wielder is Marc, and Nathaniel gets the rooster (because goats represent being aligned with satan ((aka how the rest of the world's religions sees Jews)) and Nathaniel is Jewish.)
As for the logistics of Marinette losing her memory? Raven could definitely create a spell that makes a work around that Makes It impossible for Marinette to say, do, talk, basically align with anything about her time with the miraculous or the miraculous itself, while still keeping her other memories intact so she lives out her punishment properly.
