It will take a little while before fans see The Flash Season 5 Episode 18, titled "Godspeed," on the small screen. But in its return, viewers will be in a big treat with Godspeed's coming.

After months of rumors, it is finally confirmed that Godspeed would join Barry Allen (Grant Gustin), Iris West (Candice Patton), and the rest of the gang on The Flash Season 5 Episode 18. In the series' comic world, Godspeed is a "very well-known villain." True to his name, he possesses incredible power of speed. He is even the most-threatening speedster compared to Savitar.

However, it is not yet revealed what Godspeed would specifically do on The Flash Season 5 Episode 18. According to CarterMatt, it is not confirmed if he will be fully evil or will follow the show's timeline. There is a big chance he will be seen in the future with Eobard or the reason behind seeing the future Cicada in the present time.

There is also a possibility that The Flash Season 5 Episode 18 is setting Godspeed to be the show's big bad. So far, there are only two possible characters that can be the series' supervillain, him and Red Death, seen in the Flash museum. Although it may only be an Easter egg, it is still possible.

It is also possible that the writers introduce Godspeed on The Flash Season 5 Episode 18 and he will be continuously seen until Season 7 or until the final season. Fans have been thinking of Godspeed's coming to the series since rumors began to circulate that a new supervillain would appear in Central City.

There were even on set photos that confirmed Godspeed would make an appearance on the TV series since February. A blogger also confirmed the news when it saw the script of The Flash Season 5 Episode 18 that included Godspeed in the storyline, per Express.co.uk.
