Thermal Vision
The hero can see infrared light and heat images. This allows the hero to see in the dark, perceive temperature differences (especially those left by a living person's contact with an object), and partially see through solids. In the last case, the hero can only see the heat patterns of objects touching the other side of the barrier.
With practice, the hero can judge the temperature of a target by its thermal color. The hero has an increased risk of being blinded by strong heat sources, even those that don't affect normal vision (-1CS). Thermal vision may be a consciously-activated mode or the hero's normal means of vision.
