 * Moonstone (ego): She had to balance the evil nature of her boss, the influence of an idealist Jolt who didn't know the Thunderbolts were the Masters of Evil pretending to be superheroes, and the unstable personalities of her other colleagues to manipulate the Thunderbolts into what she saw as more realistic and beneficial options than trying to rule the world or making it a better place.
