The two-part story - titled 'Shrouded' - will focus on David-Lloyd's character from the television series Ianto Jones, who was killed off in the recent 'Children Of Earth' storyline.
"I feel I know this character implicitly. The narrative of this comic focuses predominantly on Ianto, and integrates a number of characters who have been missed by Torchwood's ardent followers," David-Lloyd said.
'Shrouded' is illustrated by Pia Guerra, whose previous credits include Vertigo's Y: The Last Man and Doctor Who: The Forgotten.
The strip will debut in the next issue of the official Torchwood magazine, which arrives in stores on April 15.
