River City History is just that: peaks into the past of the setting of Walking Shadows. Bits and pieces from this feature may very well come to play in future installments of the tale, as the long dark history of River City slowly comes into light.
But Nita Dell wasn’t finished with her attempts to remove Captain Flash as a potential adversary. But she wasn’t yet willing to expose herself or Hannigan to the public yet. She knew River City wasn’t ready to accept a female crime boss, nor that Hannigan could serve as a strong enough figurehead to secure the city.
She turned to dark magic to unleash a threat strong enough to stop Captain Flash. She connected with an interdimensional monster with a name unpronounceable by any human tongue. The monster was dubbed Mirror Man and started a rampage across both River City and Atom City.
Captain Flash had no choice but to confront the weird being, which only vaguely resembled a human in appearance. The monster’s shifting frame and ability to travel from one mirror to the next made him a formidable challenge.
Ultimately the Mirror Man’s own powers backfired against him though. Captain Flash lured the creature into a house of mirrors. The thousand frames overwhelmed Mirror Man’s shifting abilities, fragmenting him into a million pieces.
Captain Flash had saved the city and in the process foiled Nita Dell’s plans again. The city’s secret crime boss now knew she would have to deal with Flash in a more direct manner.
