Unless that butterfly is somehow also Kryptonian, as its color scheme implies, I’m pretty sure that it’s just common knowledge that you can fly faster than a butterfly.
They’re not exactly speed demons.
I’m kind of surprised that we don’t just have Atom riding that butterfly. Just for the hell of it.
