I sound a lot older than I actually am. I'm actually 15 and have autism. I have no artistic talent whatsoever. I can also explain into further detail. Nick and his crew had to leave their home dimension because of the zombie apocalypse and they had to make a base on the Observatory, Nick's last hope of a peaceful civilization. After the course of about 20 years, he has made only two new allies, Sonic.EXE and Dark Nick. When the events of this animation take place, Nick just finished a civil war between him and Hunter, almost ripping his chances for a peaceful civilization into shreds. He only trusts himself, Sean, Emily, Ed, Carrie, Dark Nick, and Sonic.EXE. He can't trust even his only son, Sean the second because he didn't pick a side. I can have it where he loses his double jump and he can't change his form to anything higher than his Ultimate Form(Already had that in mind). He could also have his mind powers temporarily disabled during times of need and his sword being temporary be unable to break metal or wood and can only penetrate flesh. He could also, not use his guns period, if you'd like.
Hopefully this makes any since and you understand the pain I'm going through. I was really tempted to get Nick and Emily removed from the series, but I realized that it was my fault, not yours. Yes, my story is dark, but I have depression and was suffering at the time that my story was happening. My characters also have to deal with characters like the Reaper and an evil over lord that has an army of about 666 septilion soldiers, with deadly poisons and weapons that ether had explosive rounds, could snipe people from 700 yards, or can slaughter humans at the rate of a black hole. So that's why my characters have powers capable of destroying universes at their disposal. I need to know what powers you want to keep and what ones you want me to get rid of, but the Master Sword stays. That's my passion and it's Nick's most used weapon.
