In infinite crisis he attacked the city of metropolis and fought with all his defenders, especially Alan Scott which he left in a coma.
He later summoned an army of vengeful ghosts from his enemies and fought with Stargirl, however the girl managed to defeat him and foil his plan thanks to her immunity to ghostly attacks.
In the New 52 Reboot he is a thief instead of a ghost, he steals the Mortis Orb and used Hawkman to charge the orb.
When the orb regained its full power he creates a portal from which Julius Gates comes out and grabs him, forcing the latter to fight with him inside the portal.
He disappears along with Julius when the portal was closed by Hawkman.
-He is similiar in appearance and personality to the Paperinik antagonist Mr. Invisible.
