Desutegoro's Quirk is described to be a straight-forward Strength Enhancement Quirk, that gives Desutegoro a level of superhuman strength. This Quirk has not been shown to need to be activated. Desutegoro is capable of holding large objects that are heavy and made of metal, such as telegraph poles.
Desutegoro's Quirk allows him to carry things that are far beyond the normal human limits. However, his Quirk has not been displayed to provide him with incredible speed, like One For All does. Nor has he been shown to be able to jump long distances, or have particularly high reflexes. Despite this, it can be assumed that his Quirk is very useful against most villains in close-combat.
However, this Quirk is shown to be totally ineffective against the Sludge Villain. It is also shown to not even come close to the power that One For All has.
