The terms "tsundere", "yandere" and "kuudere" are most often used when describing female characters. However, all the definitions of them start with "a person, who...", which kind of suggests that these terms should be applicable to male characters as well.
So, can they be used to describe a male character, and if they can't, are there any other equivalent terms that can be used instead?

is the term used for male tsundere. I'm not sure if there are other terms used for kuudere and yandere but all three are also applicable for male characters, though they are more common in females.
