Technically, the three Legionnaires pictured in the flashback below are
• Lightning Lad (Glorithverse)
• Saturn Girl (Glorithverse)
• Valor (teen) (Glorithverse)
At a subsequent point in their timeline, they will be duplicated by the Time Trapper; those duplicates will become the SW6 Batch.
They're standing in front of the Glorithverse Super-Hero Clubhouse, which will become the SW6 Legion's Headquarters on New Earth.
It's only going to get more complicated, folks.
