This template is essentially a quick way to both add a link to Category:Flight (where the power is described) and also include the article in the category. What this does is both add a link to the powers description while also adding the character to a list of other characters who have this ability. Further details on the applications of this power should be included on the Character's page.
Type the following in a character's powers section. For the sake of organization the bulleted version is often used.
An override term can be added if "Flight" is inappropriate for the character.
The parameter |equip=yes can be set to move categorization to the subcategory Category:Equipment provided flight.
