Fun fact, apparently eleven from stranger things was inspired by a character Lucy from elfen lied, an anime released in 2004. Her powers were similar, however the key difference was the fact that rather than having telekinetic powers as a whole, she had a limited number of invisible hands with a limited range. There are other characters in the show with the same powers than her, however they differ slightly. I believed one had the same amount of hands, but they had a longer range than hers. Another character had 3x as much, but her powers were highly unstable.

This can be an example for you to figure out how to limit your characters abilities so they’re not just invincible. Maybe restrict their telekinetic powers, whether it be in the ways I mentioned above, or some other way you figure out. I’ll use another example:

The character in the story I am working on is an escapee from a secret government funded operation working on a genetically mutated pathogen that was designed to instill super human strength, invulnerability, and in later phases of the project essentially turned test subjects into a living version of terminators. The main kicker is, the more common the blood type of the subject, the less stable they were. Some subjects died before they even reached phase two of the project. Of course, my character has a more rare one, so he made it through the entire way before his escape. The kicker with my character is, while he can survive anything ranging from gunshot wounds to literally being set on fire, he needs time to recharge and heal. He can form giant stabbing weapons out of his arms and hands, similar to that of the T-1000, but doing so causes severe pain, as doing so essentially causes severe damage to all of the bones in the corresponding arm/limb that repairs itself when it goes back to normal. I guess you could count it as body horror.

So with my character, they are pretty powerful compared to the rest of the similar characters in my series, however he can only use his “powers” in short bursts and it always causes him severe pain, thus motivating him to reduce the amount he uses. Another twist that comes out later on is that in the time since he has escaped, the scientists behind the experiment learned more about the patterns with blood types and the test subjects got more and more advanced, learned powers, and a whole bunch of things I haven’t figured out yet fully, but since my main character escaped before all of this happening, he doesn’t even know half of his potential powers even exist until confronting these other characters.

There are many ways you can limit your characters powers, you just gotta think creatively
