Well now, this is different. A shaker/master/trump of sorts, likely tagging him during the first chapter. Depends on how much is real and how much is hallucinations.
If the only way to be immune is to be a perfect human being, nobody's surviving her attacks. And of course, she goes after heroes for their flaws instead of something more productive, likely tied into her trigger.
I will put here something I said on SB:
Faith's trigger event involves learning a secret about a hero she looked up to the hero was afraid of people knowing, and the hero freaking out and either threatening or hurting her in the attempt to keep her silence. The revelation of someone's fear turned against her, and she got the of revealing people's fear and turning them against themselves.
Faith directly targets heroes out of a misguided attempt to
help people. Everyone knows the nazis, drug dealers and human traffickers are bad and need to be stopped, but no one else can see whether the heroes are actually
good, are actually
heroes, and no one else will reveal those who aren't and stop them from hurting the people who trust them. Her belief of people only affecting bad people only compounds the problem. The reason she targeted Armsmaster specifically is because he's a very high-ranking hero and at the head of his own team: it's especially important to be sure someone in such a position is
actually a hero.
Revelations' powers manifest as Stranger/Master in this case because Colin's fears are focused on the way people see him and interpersonal relationships. It could be completely different on other people.
I haven't thought about it much, but I think the PRT would put her as a Trump, in part because of the way her powers switch with every encounter, and in part because the fear of helplessness, manifested through power nulliffication, would likely be somewhat recurrent.
Revelations' power isn't a thinker one. She doesn't directly gain any knowledge. What it does is turn someone's fears against them - for example, Colin is afraid of being helpless/powerless, and had his power nullified and lost the ability to remember his training and other things that could allow him to fight back/protect people. Revelations herself doesn't know what the fears are, although she can make educated guesses based on the results of her power.
Revelations' attack are based on both a fundamental misunderstanding of how her own power work (since she believes it attacks "sinners" and "sins" rather that fears), and an over-idealized idea of what a hero should be like.
Finally, Revelations is very minimally affected by her Shard. She's just a zealot.
