Stan Lee's daughter has revealed that the pair were in the process of creating a new superhero called 'Dirt Man'.
The Marvel supremo and comic book kingpin is said to have been working on the character just days before he passed away aged 95.
Speaking to TMZ about her father's legacy, J.C. Lee has said that she will be continuing with the development of the superhero, who said her father Stan was 'hands on' involved with, including the weekend before he died.
Speaking about 'Dirt Man' and what his powers are, she would only give away that 'it's very interesting'.
She said: "I've been trying to get him to do a character with me my entire life. He did listen to me and we have been working on a character called 'Dirt Man'.
"The last little angel we've got tucked away is Dirt Man. Let's get down and dirty, let's do what's going on and about love - let's do Dirt Man."

The 68-year-old actress and artist was choked up when speaking about Stan's love for his fans.
She said: "My father gave it all up for the fans. He loved each and every one. When I was in my very early teens and I worked at Marvel, I used to open up the fan letters. When my father could he answered every fan letter that he could answer.
"He loved them and it's all about the fans. My father loves them so much."
J.C also revealed that the family are creating the 'Stan Lee Literacy Foundation', adding: "The importance of the written word and the importance of reading is not to be underestimated. One reason why Stan is Stan The Man is because he took his craft very seriously."

Stan Lee was rushed to the Cedar-Sinai Medical Centre - not far from his Hollywood Hills home - on Monday morning. He was then pronounced dead at the hospital.
The Fantastic Four was Lee's first Marvel endeavour back in 1961. He then went on to create Spider-Man, The Avengers, Iron Man, X-Men, The Incredible Hulk, and Black Panther to name just a few.
He also appeared in all of Marvel's movies - from 2000's X-Men onwards - in a cameo role, with the latest Sony/Marvel film Venom possibly his last ever film credit.
It's been revealed that he will crop up in the forthcoming Avengers film.
Avengers 4 co-director Joe Russo confirmed a short while back that Lee has already shot his cameo for the film, telling BBC Scotland: "He doesn't love to fly, so typically we try to get him out for his cameos around the same time.
"So if we have other movies shooting on the same lot that we're on, for instance Ant-Man 2 or Avengers 4, we group his cameos together and then move him from one set to the next and kind of get him through his cameos in one day."
If we didn't have enough reason already to watch the film, which is set to be released in May 2019, then we have a very important one now.
