So I’ve been watching M:LeCT
Alright, so we're gonna bust out some theories. Or maybe not theories, but more like observations. This may also correlate to some pretty important franchises other than Miraculous, because GUESS WHAT?
MULTIVERSE THEORIES lol jk
Ladybug is the Miraculous form of Marinette. She uses a yo-yo (can you believe it, they use YO-YO for a name?), with a Special of Lucky Charm, and has the purifying/de-evilising/exorcism effect on Akumas. It's pretty evident how Ladybug is clearly much faster than Marinette, specifically displayed in S1EP4 where Marinette tells Tikki that "I might not be able to reach there in time...but Ladybug can."
That's pretty obvious of a trait to me.
Marinette also experiences a confidence boost when becoming Ladybug, and this seems to be evident. Which brings up a good point...
Observation: Marinette and Adrien are definitely not normal human beings, and have some sort of baggage that propels the personality difference between their two phases.
The first part may seem unimportant, but it explains a lot of questions. Why do we see everyone else have relatively little baggage, while on the other hand, Marinette and Adrien are constantly facing events that mimic that of a tragic anime character's backstory? Which leads us to the second part.
Marinette constantly gets bullied by Chloe, even though she is clearly more talented, and seems hopeless in pursuing her dream of finding Adrien. Adrien, on the other hand, is burdened by his father's position, and wants to be free without having to worry about these kinds of things. This is why the confidence boost increases upon them transforming.
We'll be seeing most likely more characters onward that alike, have Miraculouses. It's clear that none exist as of now, as Hawkmoth refuses to address anyone other than "BRING ME THE MIRACULOUS OF LADYBUG ET CHAT NOIR..." in his ominous voice. However, judging from the episode title of Episode 25, ORIGINS – STONEHEART, there's a possibility that Stoneheart becomes a character? Again, all of this is speculation based off on only watching the first four episodes of the franchise.
But yeah, personal baggage leading to the unlocking of Miraculous. Perhaps Plagg and Tikki chose the two, unless...
The trait of being a Miraculous is in their blood. There are currently three possibilities of who Marinette and Adrien are, as of right now what I can see: one, they are humans who were chose by Plagg and Tikki due to their baggage and giving them something of joy in life. Two, they're humans who have special blood within them, that allows for the transformation of themselves. Three, they're non-human beings who were (by plot reasons) cast down on Earth, and destined to meet each other.
I'll throw in the franchise connections once I've decided that enough proof is evident to propel more information towards the final truth: LADYBUG-MARINETTE <3 CHAT NOIR-ADRIEN CONFIRMED
We'll see how it goes on.
