See, my first impression was that the city is old (clearly it takes time for a metropolis to develop), and the mad scientist and his mutant army are new (otherwise this conflict would have been already addressed).
Go children! Fight against change and for the status quo!
The "heroes" come from Skecher shoes(I work in the shoe department at a department store) and there are comics based off of them in the boxes with the shoes. There are different character sets for the different styles(super heroes for boy shoes, girl rock band for girl shoes) One of the character sets is a team of heroes that match up to light up shoes and all have names based off of forms of light(I think), except for the girl of the team who is named "Tesla".
5 stars for evil and making me think of work when I'm not at work.
