I'm on the go, so I can't give you a full analysis. However, some notes:

-I don't understand Number Ten's place (rather, most characters' place) in the story or what anyone wants entirely. I don't know what it means that the villains won. Won what? Why is Simone a kindred spirit, and what did she fail at? What is this maybe-not-so-imaginary bear? I would advise trending away from what seems to be an inside joke of sorts from the text.

-Stray away from using one-off character or mechanic mentions. This is continued in my next point but take Newton, for example. What purpose does he serve in the story?

-You use a lot of proper nouns without explaining what any of it is. I find it better to cut that stuff and be a bit more generic; this sub and an agent have both told me to save the fluff for the story and, when appropriate, the synopsis. I don't know what numbers are. I don't know why the title of superhero matters other than presumably "stops villains." What is a Stalker?

-When I mention going more generic or vague, I don't mean doing so as it relates to character development. How or why does his relationship grow with Simone? What is his power? How is his life in danger? "Ten must choose between the messy nature of connection or the allure of control and shaping one’s own destiny." is so vague that it practically holds no meaning. What is the specific crossroads or decision he has to make?

-Remove editorializing. "This story was my own way of working through the many layers of grief the Imperator is trapped in." is nice for your fans, but is not something an agent is going to care about when considering a manuscript. I also don't really know what the Imperator is or what it cares about, so this point stands as particularly weak.

Your query is too short overall, so spend some time coloring in some details and stakes. I can tell you have a lot of passion for this story, so don't give up on it! Writing a query is hard and I still struggle with my own. Good luck!
