The comic book-based role would mark yet another feather in his cap as the 64-year-old actor has previously played Yondu Udonta in Gunn's "Guardians of the Galaxy" series, reported The Wrap.
Rooker has also worked in Gunn's productions -- "The Belko Experiment" and "Brightburn".
Gunn will write and direct the movie, which is expected to get into production later this year.
"The Suicide Squad" sequel is slated to be released on August 5, 2021.
