Paragon: A strong Spark and Tinker, and rumored to be a 'Heterodyne' as well - He's able to make high quality gear on the fly from anything, and the synergy is powerful enough that he has a Shaker rating when Tinkering. Donates a lot to humanitarian causes. Extremely popular, extremely personable.
Exemplar: His power is superpowers, basically - He can emulate any Parahuman power, and use a massive library of his own. His main limit is he can only have three powers of a type, including other members of his team. He's pretty much the strongest parahuman, period.
Luminary: Leader of the Protectorate, an Inscribed Parahuman whose power is All The Lasers. Did a whole lot for the LGBT cause before New York was brought to the Neath, still does a lot now but it's kind of slowed down by his limited appearances on the surface. Mainly it's just at Endbringer battles and other events like that.
Akashic: Namer of the Akashic package, she's invincible, unstoppable, and has a potent Thinker ability that lets her replicate Tinker/Spark works in a limited fashion, among a lot of other things. She used to have a few weaknesses, like exotic dimensional effects and oxygen-destroying effects, but Paragon was able to shore that up a few years after her career began, when they became apparent.
