The Armor Knight (also known as the Heavy Knight) is a recurring class in the Disgaea series. Armor Knights are graduates of the Knight Academy and are trained to protect royalty. At the Knight Academy, they are taught the skill, courage, and etiquette needed to become a knight and receive their armor and first position on graduation. While initially a male class, female graduates have rapidly increased in recent years and now greatly out number the men.
Armor Knights are not agile but boast the strongest defense in the Netherworld, which makes them invaluable for any form of combat, from full frontal assaults to defense missions. Despite this, they have a mild personality and see the importance of teamwork.

The Armor Knight class is introduced in Disgaea 2 and is unlocked by having a character with 5 Spear Mastery, then passing the associated bill in the Dark Assembly. They have low movement and jump, but boast one of the highest HP and defence stats in the game, with their defence going up when their HP hits critical, as well as having the farthest throwing radius in the game. They excel at using Spears.
