Sunshine

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

Description
Much of Escanor' power is a mystery whether it was a gift or a curse when he was born with such ability, but it is shown to be emitting a dangerous amount of light to dispel darkness and slowly burn and melt away his enemy along with anything in his immediate vicinity. It is also greatly amplified by the rising of the sun at dawn and severely weakens at noon. According to Merlin, it is the source of all life.
