By default, this is not necessary, as it will automatically use the article title. In certain cases, such as if an identifier is used in the article title, this can be manually specified.
A representative image of the character - ideally, artwork from the most recently released game. However, if the latest artwork is specialized for that game (e.g. the character's wearing sporting gear, driving a kart, etc.), an older image may be retained as the infobox image instead. Note that the infobox cannot be updated while a game is still upcoming: it can only be changed after the game is released.
The franchise(s) that the character is featured within. For third-party characters, this can refer to their franchise of origin.
The specific series of a franchise in which the character appears.
The first game, book, cartoon episode, comic issue, movie, etc. that the character appeared in.
The latest game (etc.) that the character has appeared in. This does not include upcoming games: the game must have been released before the infobox can be updated. Ongoing serialized comics are not included here.
Who voiced (or otherwise portrayed) the character in the most recently released game (etc.).
If only one person has portrayed the character, use this instead of "latest_portrayal".
The character's full name. Only use this parameter if the full name is not identical to that used in the article or infobox, as this would be redundant.
The character's species
The real-world species that the character is based on.
The character's gender.
The character's hometown of origin.
Important characters, groups or locations associated with the character in question.
