Hmm, a story line possibility...

Chris Thorndyke sees Sonic's head off like that and Chris goes "EEEK!", he rushes to go get some crazy glue. Sonic goes "HOLD IT! I like how I am right now, but at anytime I can screw my head back on my own body."

(Yes I have a very wild imagination)

Headless Loona still attempting to check her phone despite not being able to see anything~

You can have Amy as a toy looking for her head

Headless and armless girl with a vibe stuffed into her that she cant remove?

I just want to see how well Your art has been improved so far over the year. Could You draw Lucario training while headless?

How about drawing headless tails comic?

That would be cute. 😅
