Part 2/9:
The chaos begins with a bank robbery instigated by metahumans using their powers to incite rage and violence among the civilians. Barry, in his capacity as the Flash, intervenes to thwart further bloodshed but fails to apprehend the criminals. After the event, the police work to track down the metahumans involved, leading to the eventual entry of Oliver Queen—the Green Arrow—who is also in Central City to handle a separate case linked to a killer armed with a boomerang.
