From Apple
22.2 - Apps that contain false, fraudulent or misleading representations or use names or icons similar to other Apps will be rejected
22.2 Details
Your app or its metadata contains misleading content. Specifically, your app creates a misleading association with X-Men.
We’ve attached screenshot(s) for your reference.
Next Steps
Please remove or revise any misleading content in your app and its metadata.
Since your iTunes Connect Application State is Metadata Rejected, we do NOT require a new binary. To revise the metadata, visit iTunes Connect to select your app and revise the desired metadata values. Once you’ve completed all changes, click the “Submit for Review” button at the top of the App Details page.
NOTE: Please be sure to make any metadata changes to all App Localizations by selecting each specific localization and making appropriate changes.
