I have noticed that many recent stories are lacking the disclaimer for non-ownership of characters. Please make sure you include it within the author's notes or in story notes. Here is a standard disclaimer you can use (although you are free to write up your own, if inspiration strikes):

Disclaimer: All publicly recognizable characters, settings, etc. are the property of their respective owners. The original characters and plot are the property of the author. The author is in no way associated with the owners, creators, or producers of any media franchise. No copyright infringement is intended.

It would really be appreciated if you could make sure it is included in your stories, and add it in, if it isn't. Thank you so much for your help!
