An option that we could do in case we are worried about ever switching again is having a template in which you can either put in "Two", "2", "Earth Two", "Earth-2", etc. as the first parameter and it will style it the way that the wiki is currently wanting to style it. For example, if we change to Earth-2, then all of those inputs could make it into Earth-2.

But I do realize this is just another template to keep track of. But if we change the format now, we will have to go through every link anyway. As well using this, it would reduce the number of infobox edits because we could just take the homeuniverse input into that template and then be done.
