I finally got to this, have 3 of my comfort characters on a road trip together and made the pain car!
From left to right:
Cybersix (Cybersix)
Adora (She-ra 2018)
Reed Richards (Fantastic Four)
Reed and Six would not get along, just flat out, Reed would set off her trauma.
Adora and Six could probably get along but that would require a mini version of Catra's season 1 arc minus Lighthope fucking with them and Reed not butting in every 5 minutes.
As for Reed and Adora, it just wouldn't have much chemistry, just kinda eehh? There isn't much there, Reed is kinda less fun Entrapta.
My original 3 were Rainbow Dash (MLP:FiM), Allison Goleta (SLARPG), and Adora but I realised those 3 would get along. So I changed it up to better match the scene from A Goofy Movie, so I grabbed some different comfort characters (Keeping Adora) and accidently made the pain car.
