Free (OGL)

The Mutants & Masterminds Character Builder is a LibreOffice spreadsheet intended to facilitate creation of Mutants & Masterminds characters. It may or may not work with Excel if converted to that format from within LibreOffice, but I make no promises, and I do not intend to spend any time working on that.
