So with my thought on different yin-yang pairs that would cycle between 6/7 Miraculous, I also wanted to cover the different pairs for Felix and Marinette as I do think they are a pair that can easily use both Ladybug and Cat.
So I wanted to see if that could extend to my idea on other pairs, particularly Fox/Peafowl and Bee/Butterfly.
Which, for this, there are tweaked themes for these pairs.
Fox and Peafowl echo themes of Deception and Truth/Vision.
Bee and Butterfly echo themes of Order/Notion and Chaos/Emotion.
Bonus, Turtle/Serpent.
As this got long, going to exclusively focus on Bee and Butterfly.
With Lady Wifi introducing the concept of Head vs Heart, this is something I kind of applied to Bee and Butterfly. Emotions are chaotic and unpredictable, which can work off the butterfly effect quite nicely, while bees can reflect the Head, which relates to reason and logic, playing off the values of functionality, which has no room for being emotional and illogical.
With this in mind, it may be that this is the more limiting pair for these two.
Marinette works off both the Head and Heart. She works off what is logical, reasonable, and efficient. But Marinette is also very tied to her heart, she's emotional, she's empathetic, and it leads to her being very chaotic.
By how she is, I can believe Marinette can pull off both of them very well, but I do think there's more merit in her having Butterfly over Bee.
By how Marinette is, she naturally clicks with Bee. She is hard working, she is able to work with others and is also able to step up as a leader if required, but it's not a position she aims for or must have. She just fills that role if no one else does. Marinette naturally is a nurturer and is kind and compassionate, and reflects that mindset of others before myself. She is quick witted and usually approaches problems logically and based around what she observes (only exception is with her crush which logic goes out the window).
Marinette would click with Bee quite naturally, but by how Marinette is, there's not a lot Bee or Pollen could offer her growth wise. Only thing I can think of is Bee would help with emotional control and her self-confidence, but I do see similar issues Marinette has with Tikki popping up, as Pollen should push for work hard, be a team player, others before yourself, address disorder, ect..
Butterfly in contrast I find can match with her, but also offer better growth.
Given that Marinette is empathetic, able to work with others, can step up as a leader as required but able to step down, and canonly does grant powers to other, her with Butterfly is a pretty natural fit. It also works off Marinette's interest in meddling/giving others a boost, and having their best interest in mind.
Growth wise, Butterfly would also help with self-confidence and learning emotional control, but it would also come with learning to step back. Part of this power, in granting abilities to others, is giving others a chance to fix problems themselves. Usually it's Marinette stepping up to fix problems for others, which is fine as sometimes that's needed; but there are times people need to fix their own problem themselves. And that is something Marinette struggles with. She has to get involved, she has to fix the issue. And it just can't be like that all the time. It's not good for her, nor is it good for others to have someone come in and save the day for them.
So by power, it's a nice set up for her to learn to step back, she can still help and give what's needed, but needs to leave it to others to fix and address themselves.
Nooroo I also see being a good kwami to work off Marinette, being gentle and patient, and very empathetic himself. Given that he seems to pay close attention to his humans, given that Marinette already prioritizes others over himself, he'd probably prioritize her emotional needs. I also see him being a nice calm counter to her high energy, but able to roll with the chaos.
For Felix, Butterfly I do see being a struggle.
Felix I do see being a low empathy character, not able to really connect with others the same way, and often him caring largely extends to those who matter to him. He does know how to act and influence people, but this being a Miraculous that required emotionally connecting with others, is not really something he always clicked with.
A lot of concept art has him alone or outside the group.
And this Miraculous does require a social butterfly.
Which Felix is not.
Nor is he known to be someone inspiring and willing to uplift others, he's a more "everyone for themselves" sort.
Butterfly could be handy in helping him learn to connect with others, develop empathy more, and actively help others, but I do see it being a struggle and not something that would come too easily.
Bee though is a better stand out between these two Miraculous for him. He can match it in being dedicated to his goals, hardworking, and going about things smartly and efficiently. It also wouldn't discourage him from lashing out when justified to.
Bee would cover his need to learn to work with others, even more so than Ladybug as that's a bigger priority for bees. It will also lead to opening up to being more of a nurturer/provider, to have more compassion to offer others. Bee would be about finding his purpose, which can be him stepping up to the role of hero and helping those in need in comparison to Felix trying to spend his time living his life minding his own business.
With an adjusted Pollen to work with this, I see Felix having a similar dynamic to her like he could have with Tikki, but one that can be a little more harmonious with Pollen being more open minded/tolerable of how Felix is, as it's apart of who he is and will play into his role in the "hive". She does want him to engage and open his heart more, for a fully solitary bee shall not go far, but she can get it. She is also a 100% with him in "stinging" frustrating sources of disorder (like Chloe).
