Superman is the ringleader of this team, the man who started it all. He is DC's first superhero and came from the planet Krypton. On Earth, he uses the alias "Clark Kent" to protect his real identity and so he can be a reporter at the Daily Planet. Superman's character has gone through many different developments - whether that be a change of his origin or, in Rebirth's case, an entire rewrite and merge of his history. He's Lois Lane's husband and Jon Kent's father.
Lois Lane is a reporter at the Daily Planet, Superman's wife, and the mother to their son, Jon. She has had her fair share of villain experiences and even had to deal with mysteries surrounding her Earth-52 counterpart. She is an excellent reporter/journalist and a great supporter of Clark's.
Jon Kent is Superman and Lois Lane's son from Pre-Flashpoint. He has gone on many adventures, mainly with his father, and is Damian Wayne's best friend.
