I have a feeling that ben won't turn into a Sotoraggian. But i think zerozero would be incredibly small and walks on all fours like a baby before they get to toddler. And i think oneone would be toddler style. Threethree would be be as tall as ben was in the original series. And ninenine would be taller, and would be much more detailed than the rest, and tenten would be the most detailed and most muscular.
Sixsix, sevenseven, zerozero, tenten and threethree would be dudes while the rest would be girls. I also think the PARENTS would be eleveneleven and twelvetwelve, eleveneleven being mom while twelve twelve being dad.
God, TwoTwo gets lost, Ben returns her to her siblings, only for all four of them to pull guns on him. That'd be priceless.
That aside, I'm beginning to suspect this family at least might be clones or something. They seem to bear some similarity to the Fett family of Star Wars, the ones we've seen so far all appear to be enhanced for combat, and their names do lend some thought to the grown in an order thing.
