Question: are the human torch and invisible woman related

Answer: Yes, Created by writer Stan Lee and artist Jack Kirby, Johnny Storm is a renovation of Carl Burgos's original character, the android Human Torch, created for Timely Comics in 1939. Storm first appeared in The Fantastic Four #1 (cover-dated Nov. 1961), establishing him as a member of the titular superhero team. In his plot summary for this first issue, Lee passed on to Kirby that the recently-formed Comics Code Authority had told him that the Human Torch was only permitted to burn objects, never people. Over the course of the series, Johnny being the little brother of teammate Susan Storm a.k.a. the Invisible Girl was one of several sources of tension within the group.
