Single post in Zenith mode Marshadow

This doesn't fall under that rule assuming OP means "Zenith" mode, as it's a canon form that just isn't on the site. There was a large thread about this but it was deleted due to inactivity... I don't remember a lot of the details but one argument I do remember is that since Xernas got its active mode in the party instead of just in sparing, why not Marshadow? Also there's Darmanitan, which uses a form change item instead of battle. And the shiny/regular difference I think is more noticable too? Anyway here's the original thread link, for reference: https://pokefarm.com/forum/thread/220562/Adding-Marshadow-Zenith-form/ Fair warning: even if this was accepted, it may take a while to get it done, the art staff seems busy (the "this should already exist" tone of your post likely won't help either tbh)
