>>11014561Redeemers are, in the Spawnverse, Heaven's version of Spawns. With Angels kidnapping born again Christians who did horrible things before renouncing evil and changing their ways and turning them into "Redeemers", who themselves are disposable foot soldiers who if their armor is damaged/opened, explode into Heavenly napalm that burns everything around them when they explode.
The original Redeemer was a former asshole teenage delinquent who found Christ in juvie lockup and became a born again Christian who worked at a soup kitchen and training to become a minister. He was purple/gold and only appeared once, mainly to promote his action figure (as Todd created a TON of Spawn villains for the 90s toy line but only used a bare handful of them in the comics and only once.
The current Redeemer is the gold/blue version, who also has wings that the original version didn't. I don't recall the new one's backstory except that he's now an ally of Spawn due to how Todd writes Heaven as being just as evil as Hell/Satan.
IIRC the silver/black version is just Todd repainting an existing figure as a chase figure for his fanboys to hunt for at stores.
