Hearing about the death of Arion during the attack by the Princes of Darkness, Knightley took the name of Arion and began using it to gain respect from members of the magical community. He assisted Earth's mystics during the Infinite Crisis.

However, a year later he had fallen on hard times and took to hanging around the Oblivion Bar, hitting on women to little effect. When the real Arion appeared from the past, he kidnapped his "successor" and used him as an advisor. When he was defeated, he returned to his own time, leaving Knightley to be arrested in his stead.
