While their presence certainly requires more work for farmers and trainers, Durant have often been described as the laziness pokemon. Unlike Slaking, whose lethargy only impacts themselves, those few Durant who fight only half the time have the mysterious ability to make other pokemon every bit as lazy as they are.

Battles involving these Durant are extremely slow affairs, where continual damage from attacks such as toxic and leech seed can acquire immense importance. They are marked by frequent pokemon switches on both sides, for no one wishes to be caught with a lazy pokemon, although it can not always be avoided. Durant teams typically rely on transferring that pokemon's laziness onto a foe, than bringing out a teammate which can force their newly lazy foe to remain in battle while powering up until they become practically invincible. Typically, these Durant are unable to compete in top-level leagues, but in alternate battle formats, especially those which restrict replacing pokemon, the Durant can turn their laziness into virtual invincibility; there, they are as popular as Garchomp.

Although this ability is rare among all but specially bred Durant today, it is thought to be basal to the Durant species, so early biologists described these Durant as the "true Durants". In time, this term was shortened to Truant, and applied both to Slaking and to anyone who fails to give their full effort in important tasks, or worse, fails to appear at all. It is said that if Durant ever learn to spread truancy directly to humans, civilization would collapse, for there would be no one left who could work quickly and productively enough for society to function. Yet enough people would still go through enough of the motions to fool many others into believing that nothing had changed.
