"This unauthorized use of Bandai/Namco's intellectual property falsely suggest Bandai/Namco's sponsorship or endorsement of your website."
Sounds like a disclaimer at the top of the webpage or when you enter for the first time to the effect of "This is a fan-created website. This website is not sponsored or endorsed by Bamco. All rights reserved blahblahblah" or whatever the proper legalese is would take care of that quite nicely.
