Sun's Bane

Description
Sun's Bane is a power that is said to be unlike any other. It is at his weakest at midnight and his power peaks at noon. Starting from sunrise, It's power begins to increase and he begins to grow larger and is able to summon heat from the sun. with the process reversing with the setting of the sun. In the daytime, the quirk boosts the physical strength dramatically of the user and they are able to radiate intense waves of light and heat easily capable of melting metal and vaporizing stone. A old wizard estimates it's power to that of the actual Sun, the source of all life. Sun's Bane is able to be imbued a sword (Excalibur) with magic power, which causes the slashes from his sword to also release waves of fire if he swings it. The Intense power of the Quirk is extremely straining and the user is unable to control the quirk as it passively activates during day time.

Weaknesses
Sun's Bane is weak against any poison type attacks, as well as any water or ice type attacks as they are likely to cancel out his heat. He also takes way longer than regular people to regenerate wounds. it is also extremely slow in his daytime form because of the increase in physical attributes.
