Energy Saver

Energy Saver (エネルギー) is one of the several Quirks utilized by Gigantomachia.

Description
Energy Saver allows the user's body to function on very small amounts of nutrition and hydration, as well as allow them to process without much sleep.

Gigantomachia has demonstrated this by being able to initiate continuous assaults for over 48 hours without rest, and only requiring three hours of sleep before resuming. It is presumed that the increased amount of physical energy and stamina gained through his original Quirk, Endurance, grants him an ever lesser need for food, water, or sleep to survive.
