Bartholomew Allen (Earth-4605)

"Imagine this, you're home alone, it's late at night, and you live in a bad neighborhood. You're scared. You've heard rumors about a gang that's been breaking into your neighbors' houses, and you're worried they'll be coming for you next. There's a knock at the door. You answer it, and you're instantly knocked to the ground as the burst in and start trashing your house. All hope seems lost. But in a flash, everything's changed. The gang's all tied up, your house is fixed, and you see a costumed man standing triumphantly. It's him. It's the Flash!"
