The Superhero World has three people undergo notable changes.
Bolt goes from boy scout superhero to supervillain after he became disillusioned with how none of his actions actually had a lasting impact and he began to take drastic measures to spark change for the better.
Echo: Under Metalheart's teaching begins to understand that helping people enough and that a superhero should never make decisions for somebody else regardless of their personal opinion.
Alexandra Stone: becomes nicer, more carefree, and more willing to act altruistically. While it's a huge change from before, she's still secretive and very nasty to be on the bad side of.
