Module:HeroBattle

For use on Hero Battle and possibly other locations later on. This module can be used to output Hero Battle data, including the next rerun date, total number of reruns, and the current active Hero Battle.

Only one parameter is used, the name of the relevant Hero Battle:

{{#invoke:HeroBattle|Sophia}}

This outputs:

Rerun 187 times to date
Next rerun: April 9, 2023
