The relaunched title was given an initial printing of 45,000 copies, and will be followed by a reprinted edition with a wraparound cover on Wednesday (June 20).
Valiant is rolling out a third edition featuring Cary Nord's original pencils on the cover in anticipation of continuous high demand for the title, Bleeding Cool reports.
"This is an outstanding performance for an independent publisher, especially with a debut title. We look forward to great things from Valiant in the months and years to come," said Bill Schanes, VP of Purchasing for Diamond Comic Distributors, Inc,
Eisner Award winner Nord entered an exclusivity deal with Valiant in March, and will continue to provide artwork for X-O Manowar.
X-O Manowar #3 goes on sale on July 18.
