The Flash: 24 WTF Moments
4. Young Barry Dies (And So Does Dark Flash)
As Dark Flash faces off against Prime Barry, who is trying to stop his multiverse-meddling shenanigans, Dark Flash attempts to stab him with his bladed arm.
At this moment, Young Barry jumps in the way of the blade and is mortally wounded, in turn saving Prime Barry's life.
And of course, because Young Barry and Dark Flash are effectively the same person, if Young Barry doesn't exist then neither can his older Dark Flash self, causing Dark Flash to quickly evaporate to dust.
That's... one hell of a neat way to quickly deal with a last-minute villain, right?
