...
I'm sorry for that terrible, terrible pun.
It's not even a pun.
It's an anti-pun.
Also, I see it as "Dib-er-us" instead of "Di-ber-us". XD

Here's my early Halloween art!
Being Pre-Halloween and all, I need to get started already!

This seriously stemmed from me saying "I want to draw Di as Cerberus."
And, here we go!

Middle head has permanent angeriness (and possible rabies).
Left head is Dopey Di. ...that was my fault.
Right head is Edge Di.
Because she's always on the... edge? Ehhhhhhhhhhhhhhh?
She's also spread out away from the other heads, for good reason. She's the only sane one...
