Original Description:

The young Auto Pony Gang in gen 5 style (a base that is). Left to right; Windblade, Hot Rod, Sunstreaker, Sideswipe, and Bumblebee. There’s two other ponies in the group too but there wasn’t any room, but these are the main ones. I call them the “Young Gang” because they’re similiar in age to our main characters in gen 5, well except for Bumblebee but his alicorn magic keeps him from aging so he never aged past 25, and since he never became powerful like some other alicorns, he never grew and is normal Stallion height, shorter than an average young alicorn.

As you can guess, Sunstreaker and Sideswipe are twins, and they’re big trouble makers. They’re kind of crazy, although Sunstreaker is more insane than his brother.

Hot Rod is probably the youngest pony in the group.
