These are units which have been flagged as Male in the game.
Administrator Note: You may not agree with the gender flag set by Gumi, but the wiki will match the in-game data, not your personal preferences. These typically are reserved for "human" units, as monster/robots/etc. fall under Genderless regardless of how they appear or are referred to (e.g., "him", "her", "it").
You can see a unit's gender in-game by going to Home\Menu\Unit Guide\<select character>\<check icon in bottom right of unit nameplate>
