Lois Lane
In DC Rebirth, the "New 52" Lois and Lana gained superpowers due to the solar energy explosion caused by the death of the New 52 Superman. This results in both Lois and Lana becoming Superwoman, with Lois possessing all of Superman's traditional powers, while Lana has the ability to absorb solar energy and release it in other forms. Lois later dies at the hands of a female Bizarro, being overloaded with solar energy the same way Superman was killed.
