This version of Leonardo first appeared in Loops, summoned by Pai-Doth Noor to save the god's younger self, along with three other time-displaced versions of Leonardo. In Swan Song, Leo is revealed to have had a romantic relationship with Raven Shadowheart, also known as Radical. Radical's arch-nemesis, Complete Carnage, appeared from a brick wall one day whilst she and Leo were out for a walk, and snapped her neck, killing her.
