I give you two minors that need some guardians that can put up with powers.
Klara Prast makeitgrow is from Marvel 616: The Runaways. She is technically like 13, but due to time travel she is pretty old. She can talk to and control plants. In her time she was called a Wonder, but that just means she is a mutant.
Bellatrix Black ringingbells is from Harry Potter and often known as Bellatrix Lestrange. This smol child is 10 and a handful. She isn't quite crazy yet, but she has her issues.
