I will try to create a visual guide in the near-future but for now:

Iron Sight: grey guard colt, co-leader (seen above). Cure All: red filly medic. Bolt: little blue colt with fun shoes. Rosette: lilac filly/ Bolt's sister. Lily: Bat filly that's adorable Amber: brown and orange filly, oldest, leader Patchwork: green craftsman colt/ Nova's BFF...umm, Honeycomb: the best mom in the wasteland, everyone loves her- confirmed. I think that's everyone important. Obviously there's Nova too! He is the legendary antithesis of all the terrible FOE Mary Sue's that are master combatants, have pipbucks, save the wasteland, and try to be cooler than Littlepip. Which is impossible! Littlepip is the greatest haha
