Entering the character creator, I knew his name, archetype, and power sets. Several weeks before, I had created Cluster Buck, a thugs/pain mastermind. I was curious to see how the Pain set would work for a corruptor. "Pain Domination" does not sound like what it is, which is mostly a healing and team buff set, with a couple foe debuffs. The developers did their best to bring something like Empathy to villains, having already committed to never bringing Empathy itself.
He got transferred from Infinity at the same time as Cluster Buck. I don't think I purposely moved both my Pain guys, but I did want to make some room. He eventually would have aligned himself as a rogue.
