We were recently introduced to the New Harrison Wells who hails from Earth 19 (aside from the other three):
- Cowboy Wells (Possibly Earth-18)
- Steampunk Wells (Stated as Earth-17)
- French Wells (Earth-?)
- Hipster Wells (Earth-19?)
The funny thing is that the Hip Earth is Earth 16.
Earth-2 wells does not trust him and we’ll have to wait to see if his distrust and gut feeling proves that Hipster Wells is evil.
According to DC Comics:
Earth 17: A world wasted by nuclear war. This does NOT fit Steampunk Wells.
Earth 18: is the Wild West universe. This fits Cowboy Wells so we have to assume that he comes from here.
Earth 19: Earth Gaslight. The same earth with Gaslight batman. Mostly Steampunk style stuff which fits Steampunk Wells.
Unfortunately, the Arrowverse takes liberties so we gotta trust Cisco Ramon that Hipster Wells is from Earth-19. Maybe Earth-19 is Earth-Hipster in the Arrowverse?
Only time will tell.
