Godspeed (Infinite Multiverse)

On this Earth, things diverge from the norm. Eobard Thawne succeeds in killing Barry as a child and now has to create another speedster for him to go back home. From the comics, we know that Godspeed was Barry's partner in the CCPD before his brother died and he lost himself, so I want to show the hero that Godspeed could have been. its my first time writing. Please enlighten me.
