Sunshine

is a unique power possessed by the Lion's Sin of Pride, Escanor.

Description
Much of Escanor's power is a mystery. Whether it is a gift or a curse nobody knows. The ability itself relies on the time of day to determine how powerful Escanor is, midnight being his weakest and Noon being his peak. It also seems to affect Escanor's body and personality, making him larger and more muscular. His ability seems to be uncontrollable and can burn,melt or reduce to ash anyone with his presence. Sunshine is shown to be an incredibly dangerous ability emitting dangerous amounts of light, which can dispel darkness, and can be turned into a large scale implosion of magical power, with Escanor at it's center. According to Merlin, it is the source of all life.

In his fight against Galan, Escanor's power level was shown rising by 5 points at an unspecified rate. This shows that his power level increases steadily from one hour to the next, instead of him getting sudden surges of power.
