Susie is the daughter of Lucille and George Tompkins and the niece of Lois Lane. Her preferred pastime seems to be making her aunt Lois's life complicated with her overactive imagination.

  • Susie was sometimes depicted as having red hair.
  • This version of Susan Tompkins (Earth-Two), including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
