Dr. Usa and Rubber Bunny Villain Barbit Fused TF! (Patreon)

A character born from a collaboration(?) with 羊谷日辻 san,

 It's like Dr. Usa and Rubber Bunny Villain Barbit have fused together! 
(Below, I'm only posting my own drawings, and linking to others' comments)

There was this conversation on Twitter, after which I posted this,
Then we talked more and Hitsuji-san drew on their end too, The color scheme was finalized here (so cute)
Then an overseas artist named Ariana drew this (super skilled)
And Hitsuji-san colored it! (wonderful) That's how it went!

As a extra, I found a doodle I drew around 2022.

I hope you all could feel the... torrent of Dr. Usa and Barbit...
