The Little Witch of the Stark Family

Blurb:

What do you think of Cynthia?

Tony: Hmm, my little girl? She's only the second-greatest genius in the world. (￣▽￣)~* (Obviously, I'm number one.)

Captain America: She's a thoughtful, attentive young lady who's great at taking care of people.

Natasha: Come here and snuggle up in your big sister's arms, cutie! (*^▽^*) Face-in-cleavage.gif

Hawkeye: She makes the most delicious cookies! (Emphasis) My daughter (emphasis) loves them!

Banner: [Before he can say anything, the impatient Hulk turns green.] Hulk likes sweet honey!

Thor: Cynthia is just like my mother, a gentle and intelligent lady. (Narrator: What kind of comparison is that?!)

Doctor Strange: Dr. Stark? One of the rare surgical assistants who's actually convenient to work with.

Spider-Man: Sister Thea is super nice, super gentle, super amazing, and she even gave me Avengers-themed desserts and the same glasses as Mr. Stark. She taught me quantum physics and agreed to go with me to a school reunion... It's just that sometimes she's a tiny bit strict. Looking-at-fingers.gif

Loki: (Going crazy.gif) A bunch of blind, brainless idiots! Can't you tell that she's a vicious monster of a demon queen?!!!!! She's obviously devious and cunning, sweet-talking while hiding a dagger, smiling while plotting against you, cold and heartless, ruthless and murderous... (Sobbing, dragged away by Thor with a gag over his mouth.)

Thor: Sigh, my brother is lying again. ╮(╯▽╰)╭ (Loki: Thor, you big idiot!!!)

A pile of purple potato ashes: (I think I can still be saved, Er Kang reaching out.) That woman is no good... Could you at least listen to Loki...

Doctor Strange (stamping it out, while his magic cloak disdainfully sweeps away the ashes drifting through the air): You know too much.

The east wind is coming.

The story begins with Iron Man 1, and its direction is similar to the movies in some ways and different in others.

No Civil War. The outline and basic direction of the plot were decided while Avengers: Infinity War was in theaters.

If you don't read too deeply into it, it's a sweet, satisfying, lighthearted story. If you do, it's a sweet, satisfying, lighthearted story that becomes more unsettling the more you think about it.

JARVIS is around the whole time, and there is no Vision. There is no Friday, but there is a female AI named Alice. Her personality is similar to Friday's in some ways and different in others, since the heroine is the one who mainly raised her.

The heroine has no romantic pairing in the main story.

She's adored by the whole team. Whether the Avengers dote on the heroine or the heroine dotes on the whole Avengers team is a matter of perspective.

Happy ending, by the usual definition. But if you insist on looking for tragedy, think it over and read between the lines, and you can find some.

No X-Men. Professor X, Magneto, Jean, and the rest are far too overpowered for the author to handle the plot logic, and the author hasn't properly watched the related movies either.
