Series writer Joshua Dysart will team with artist Mico Suayan on the comic, which arrives in February.
"Toyo Harada has a vision for the perfect future - and it's one that he will realise with or without the consent of the rest of humanity," said Valiant. "In order to achieve it, he's built a private army of hyper-telekinetics within the Harbinger Foundation.
"But what was the turning point that led Harada to the despot's path? And how will his vast ambitions soon impact the whole of the Valiant Universe?
"As the 'Renegades' storyline spotlights a new generation of heroes monthly in Harbinger #6-10, discover who - or what - changed Harada into a force beyond all human reckoning."
Harbinger centres around the struggle between Harada and a group of rogue psychics who oppose his plans for world domination.
The title was relaunched in June as part of Valiant's revival.
Harbinger #0 will be released on June 6.
