There's also Venom and Widow.

Each hatchling (except Noveau Rich) have follow up images, and a lot of them. It'll be easier to find them all on derpiboou

Also Eclipsa- daughter of Spike and Midnight Sparkle

Angel Cake-daughter of Mrs Cake and Spike

Serana-daughter of Spike and Cadance

Vanity-daughter of Spike and Nightmare Rarity

I have a bunch of them but in sort order they're all daughters of Spike and a bunch of anthro versions of MLP characters. (With the exception of Twi bot)

In order there are: Nebula, Twi-Bot, Sunflare, Noveau Rich,

There already is a hatchling her name is Vanity. And the breeding is next I believe

I mean I’ve got plenty of ocs left but I am broke

On second thoughts maybe widow would work better?

Well you can choose any of my hatchlings, but if you need me to choose one, then how about Nebula? Be interesting to come up with wild ideas for her
