Tardis:Infoboxes

Infoboxes are cool, but they're not the main purpose of an article. They should be only a summary of what's in the article.

With in-universe articles, you should avoid putting information in the infobox that is not within the artilcle proper. There's greater leeway with real world articles on this point, as it's uncommon to put things like an episode's runtime, for instance, within the body of an article.
