The Redeemer is Heaven's answer against the ongoing war against the Hellspawn. Tasked with the goal to kill Spawn, the righteous warrior was gifted Heavenly abilities and powers to use them to protect the heavens.
Scott Keck sounds absolutely awesome, but he sounds a bit too on the nose as a bad guy. Redeemer isn't really a bad guy, but more of a nemesis to Spawn, if you catch my drift.
Alec McClure is forgettable.
John DiMaggio I could see working. The performance is good but coupled with barely any material and a voice that doesn't really scream Redeemer (Heavenly but willing to get down and dirty) I kinda have to put under Scott. Sorry, John, still love ya.
