Omelette Robotnik Chao!
Various things I was embarassed to post either because they discuss Seahorse dad stuff or health stuff.
ALSO GENUINELY SHOCKED IVE NEVER SHARED THE FACT THAT STARLINE AND VOLTZ END UP HAVING A BIO KID TOGETHER. Her name is Plazma and she was designed by @berrycontrary (my online sibling GIVE HIM LOVE!) She is genuinely such a treat.
On the one hand, I’m not sure I like Eggman being a “father” to Sage. I think he works better when he’s an egotistical loner, as a foil to Sonic and his many many friends. I’d prefer it if Eggman saw Sage as a great creation and patted himself on the back for his genius, rather than loving her as a daughter.
On the other hand, I do like the idea of Sage, Belle and Omelette (a.k.a. Eggette) hanging out as a trio of sisters who can’t decide whether to suck up to their dad or call him out for his villainy.
And hey, let’s throw in Surge as a chaotic stepsister. Why not?
