|For the book, see VISSER|
A Visser is a rank in the Yeerk army, equivalent to an Andalite Prince or a human warlord or general. There are forty or so Vissers. They are one rank below a member of the Council of Thirteen. To obtain the rank of Visser, a Sub-Visser has to climb the large hierarchy, slowly going lower in number designation. Every notch up in the ranking is accounted for either by that individual's achievements or by the demotion (or elimination) of their superiors, so usually every Visser must be ruthless and brutal as well as conniving and powerful.
