The reveal that The Flash’s Solovar will be a villain with evil intentions toward Earth-1 means that the two-parter will probably take viewers in some seriously unexpected directions.
The character from comic lore was actually an ally of the Flash and a just ruler of Gorilla City.
Comic fans may be surprised to learn that Solovar will be a bad guy.
