First we have Thorax and Pharynx, twins. Since Thorax never had his metamorphosis, he took his place as a soldier along his brother.
Ocellus, the first try of Chrysalis into creating a heir, because of her weak state due to not consuming love, Ocellus came way too sick to be a fit ruler.
After the rise of Nightmare Moon, she moved to the Everfree Forest, and had an affair with Rainbow and had her pride and joy, Venom Sting.
She had two more childs with her “garden”, Naiad (pink and blue one) the child she had with Lotus, and Amanita (Red with white spots) her daughter with Lilly Valley. Of course they don’t have any specific role in the hive, but she is happy with them.
