Debunking the debunkers???
So whenever there is a new fan theory in miraculous that split the fandom in the middle, I like to play devil advocate and side with what the fans don't like. (just like the adrien is a sentimonster theory. look at where we are now)
sadly there are not many Lila is Manon from the future theory videos on youtube (most are just people calling the thoery and people who believe it stupid). Here is why your points are stupid.
1 - "How can you say Lila is from the future and she can't even tell what is going to happen to her"
well that's simple, LILA is not supposed to be in the present, but she brought herself to it. so she is altering timelines, the stuff that she is going to know that will happen to her is whatever is going to happen to Manon. NOT Lila. She would not be having a "second chance" at life and knowing that Gabe would kick her out of alliance, or not be invited to the ball, or be exposed by Marinette because it didn't happen and it wasn't supposed to happen because she is from the future. Remember the fact that Marinette is Manon's babysitter in this time period that Lila travelled to, so she would be many years younger than Marinette and Adrien and we wouldn't know what would have happened to Gabe in the future. So your point is debunked.
also the only times Bunnix ever messed with time was when the world was going to end or did end because of something Marinette did, she refused to let Marinette go back in time and fix her mistakes with losing the miraculous' or losing the Butterfly miraculous. She didn't even tell her who the new holder was.
2 - "Chris referred to the new hawkmoth as the woman he loves... but it's actually Lila and not Manon"
Yes we see that Lila interacted with Chris and that he did have a crush on her. But also that quote about Chris being in love with the new Hawkmoth is a "deleted scene" (allegedly) however the possibility of Chris being in love with Manon is still there. which people believe alludes to some sort of time travel between the two because (1) they were both fighting over the rabbit Kwami (Trixx?) which Chris becomes Time-Tagger and again, if Manon did time travel she could have used time tagger and also be Lila from the future. We don't know if he really is WAY older than Chris in adult Ladybug and Chat Noir's present (also that would be very weird to have a teenager pinning over some grown woman, unless it IS Manon)
3 - "She has the pictures of Nadja because she wants to use bad publicity to take revenge on Gabe"
first of all LIE-LA she was always known to manipulate people by saying the most outlandish lies. If she wanted to she would have already told Nadja about Gabe being Hawkmoth and everyone would have believed it. Nadja is very out of place on the board and the only thing that doesn't make sense is why she is only shown to be connected to Adrien and their teacher and not Marinette. But for Lila to have her on the board for the bad press is NOT it, because she could have ruined Gabe with or without Nadja.
3 - "Lila looks like her "other mothers" (the woman she is lying to) and Kagami looks like Sabine so it doesn't make sense"
First of all, I can't explain to you why Lila's other disguises looks like her other moms when she only used her Lila look. it doesn't make sense, but Cerise LOOKS LIKE Nadja. Also the writers are kinda racist, they make all the asian or mixed asian characters the same with that blue/black hair. and the point with Kagami was that she was supposed to kinda look like Marinette because Adrien didn't realise at the time that he actually did like Marinette. But the excuse of "we don't know what Lila actually looks like, Cerise could be fake too" is weak if you're using it to attempt at debunking a fun theory.
4 - "Manon wasn't the one manipulating people it was her akumatized version"
but it's the fact that all of Lila and Manon's akumatized versions have the "manipulating people" aspect. Also Lila using her (shitty) lying abilities to getting what she wants, and Manon uses her childlike innocence to try and get what she wants. But they both always fail because of Marinette.
5 - You can't deny the flowers on her design it's not stupid
common costuming is very important. designs are very important. do you not know what Marinette and Adrien's designs are? it's their colours inverted. LITERALLY from their hair to their shoes. It's not just the one flower on Manon's overalls that is Lila's name. It's THREE flowers, one for each name.
6 - "Manon loved Marinette, why would she grow up and start fighting with Marinette"
again, you're missing the point. (1) Manon is a child when we see her "present self" so she will be different, she will be more innocent, she will love Marinette. (I wouldn't say she was rooting for adrienette). But we don't know what happens in between this (yet) we don't know if Marinette upsets her. Marinette already ignores Manon A LOT for Adrien, especially when she's supposed to be responsible for her. She's always dumping her off to be someone else's problem. So yes, there can be a resentment towards that. Yes when Manon grows up she can dislike Marinette and travel back in time and sabotage things or at least try to. Sometimes your greatest enemies are someone you once loved or cared for.
6 (b) - "the theory says her and chris are in love, how can that be if she is trying to date adrien"
do you not know how girls who don't get enough attention or love at home act like? do you not see how Nadja being busy could affect Manon, do you not see how Marinette always ditching her for Adrien could affect Manon? Also a revenge plot is a revenge plot, you don't care who you're hurting. We literally see from Gabe how his wife was dead yet he still had a thing for Natalie, while also tormenting the people of Paris for his wife. We also don't necessarily know if Chris and the Hawkmoth(/Manon/Lila) of the future are actually dating, he could just be obsessed over her. So it's still not a stretch that she would hurt Marinette by flirting with Adrien. AGAIN she was not and Adrienette shipper.
7 - "If Lila was really Manon why would she disrespect her mother"
uh because she is in her villain arch? because she is in the past? BECAUSE NADJA DOESN'T KNOW THAT'S HER CHILD?! you also contradicted yourself by saying that Nadja was busy but had time for Manon but then went to saying that Nadja was too busy that she wouldn't even have the time to pay attention to Lila/Manon scheming. So which one is it? I also feel like us seeing the first woman that Lila uses as her mother kinda foreshadows that maybe Lila really does have a mother who has no time for her. Clearly she keeps finding them, it's her comfort. it's like Nadja.
8 - "The only reason the show makes the theory canon is because of how popular it is"
this is not Adrien is not a real boy level theory. I have not heard of this until like two days ago. so we don't know what will happen with this theory.
Manon being introduced in the pilot episode could be foreshadowing the fact that she will be the next person to fight Marinette/Ladybug
"Manon can't be Lila because in Simpleman she was helping Ladybug and Chat Noir" - yes because she was a child at the time and she was with her friends and she (at the time) wanted Ladybug to win. You people really don't realise how people change. Look at Chloe, bully to good to bully again. Look at Felix, spoiled brat and creep to antagonist to hero(?)
Lila's photoshoot with Adrien mirrors Manon's photoshoot with Adrien
Lila is recruiting the kids. She's always seen at one point babysitting the younger siblings of Nino and Alya, (and I think Manon too) why? because she needs to start building her army. again, she can still be Manon.
we were already told that we were shown Lila's motive awhile back we just weren't paying attention to it. it could have even been shown with Manon.
Smarty Pants' whole rant about using the Manon/Lila theory and making it about Jesus Christ (which made me uncomfortable) and used the example of how Manon is another name for Marie or Mary and only talked about the "wished for child" but completely glossed over the "rebellious" and "bitter" definitions. so it only adds on to my point, Manon is bitter about something
I'm finding the reason a lot of people who HATE this theory hate it because Manon is a child and they are probably uncomfortable with the idea. and I only think this because of how passionately a lot of people speak towards Manon and the language they use towards the people who talk about the theory and the theory itself.
