You want all the characters in Ray Bradbury's classic short story collection, "The Illustrated Man?" That's a tall order. All of the eighteen stories in the book are unrelated, and so they all have their own, individual characters. This is not a novel with characters who appear again and again, chapter after chapter.
I went through some of the book for you and have listed a mere fraction of the characters found between the covers of this imaginative, science fiction compilation:
First, there is the the Illustrated Man himself, with tattoos all over his body.
Now here are some of the individual stories with their major characters:
George and Lydia Hadley, Wendy, Peter, David McClean
Barkley, Woode, Stone, Hollis, Applegate, The Captain, Lespere
"The Other Foot":
Captain Hart, Martin
"The Long Rain":
The Lieutenant, Simmons, Pickard
"The Rocket Man":
Doug, Dad, Mom
And on and on. I'm not sure what you want such an exhaustive list for, but I hope this helps to get you started.
