Scans or it didn't happen.
you don't know what you are talking about
1.prime beat 3 falshes before they BRF him into the speed force
2.prime beat a flash from another universe after he escape the speed force
3.in the sinestro corp war prime beat 2 flashes who were trying to speedblitz him but they didn't have a chance
SBP only lose to flashes whe kid flash was bring back to life and when flash was fully tapped into the speed force and prime was still dodging his punches
Not that it matters. Being able to beat characters that can't touch Zoom doesn't mean you're fast enough to catch Zoom
The same way Bart broke his nose,and why are you still using Countdown?Because it's all he's got.
Countdown: The series so bad that the event it counted down to ignored it completely.
