Template documentation (for the above template, sometimes hidden or invisible)
This template is a navbox that lists the doppelgängers of an input character.
Type {{Doppelgänger}} where you want to use it with the character's name you're wishing to see the doppelgängers of in the first parameter. The second parameter is reserved for an earth designation. For example, Oliver Queen does not have an "(Earth-1)" tag next to his name, so we would add {{Doppelgänger|Oliver Queen|1}} to his page. Whereas, Oliver Queen (Earth-2) has an "(Earth-2)" tag in it's page name, so we would only need to add {{Doppelgänger|Oliver Queen}} to his page.
The show parameter is reserved for if the character is prominent in one show over another.
Be sure that all doppelgängers have the appropriate redirect pages. For example, in order for Oliver Queen to show up in the template, we would need the page Oliver Queen (Earth-1) to redirect to his page.
