Injustice: Gods Among Us hasn't finished expanding its roster, with further characters expected beyond the Martian Manhunter.
NetherRealm boss Ed Boon confirmed on Twitter that more DLC is planned beyond Martian Manhunter.
"No he is not the last," he said, adding, "Next one is a big fan favourite request."
Martian Manhunter is the fifth DLC character to be released; Injustice had planned on four, delivered via a Season pass, but responded to fan demand for a fifth.
The green vigilante drops on July 30.
