Con man Dan Rivers operated under the alias Swami Riva in Metropolis in the 1940s. He was the first criminal to use Kryptonite against Superman, although at the time he was unaware of what he was actually doing.
- This version of Swami Riva, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
- The Kryptonite seen in Superman #61 was colored red, but affected Superman like Green Kryptonite. Reprints and flashbacks have re-colored the Kryptonite green.
