I started out with the idea that my hero was a mega fanboy of all the supers, he studies them, tracks them, knows everything about them. Then at a superhero signing there is an attack and he steps up, manifesting lightning/electrical powers. Later in the creation it came up that he now manipulates supers and events to form his super-team and to bring the titanic forces of heroic good and super villainy into conflict. His Benevolent Mastermind aspect will be fun to see in action and combining these two things together he became The Conductor.
As things evolved, it turned out the members of our super-team all went to school together, Nigel Goldstein loved everything about supers then and went on to study them at uni looking at the psychology and philosophy of heroism, vigilantism and the arch nemesis.
I havent worked out the details of his powers yet though some will include his hovering, levitating objects, electrical device control, EMP and shocking things. And somewhere in all of this his weakness became 'Destined to be a Super-villain' - he will do what he must to bring the struggle to earths mightiest heroes...
I like the other characters as well, Steve with his Minecrafty powers and cultist backstory, Seraph fun loving career super fueled by fire and her un-super sister Val whos troubled past combine with her training to complete the team.
Here is The Conductor in his special suit complete with conductor plates, protective padding (they are not fake muscles, nope not at all), the headset, aerial and more.
