Thomas Wayne - Reanimated Corpse - Earth-32 - Batman: The Dawnbreaker (2017)

Having been gunned down in a dark alley during a mugging, Thomas Wayne's death had a terrible impact on his son Bruce, filling him with a void of darkness, despair and loneliness.

Bruce tried in vain to bring his father back, only for the process to reveal that it was impossible by Oan technology to revive his parents, forcing him to look for extreme measures and make a deal with the "Man Who Laughs". 

"Fear of the Dark" 

Believing that his Green Power Ring was capable of being the most powerful weapon in the Universe, Bruce demanded that the device brought his parents back to life so that he could continue living with them. He mused that he would even give up the ring if he could successfully carry out the resurrection. 

However, despite the Power Ring being corrupted by its new owner to operate far beyond the capabilities of previous Lanterns, the symbol of will was unable to completely bring back Thomas Wayne. Instead, what was produced was a reanimated corpse barely capable of performing human speech, quickly severing the ties to the ring and collapsing back into a heap on the floor.
