  • This version of Joan Shanley, 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 event and later restored following the rebirth of the infinite Multiverse during the Dark Crisis of 2022–2023. Even though other versions of the character may have appeared, this information does not apply to those versions.
