Here is the second form induced by Chopper’s special “Rumble Ball” he creates for Mira, Imp Point.
This form is speed incarnate, and allows Mira to become a speed demon in the air. She also becomes more flexible, and gains a greater reaction time. Assuming this form, however, takes away the benefits of being a dragon. She loses the ability to breathe fire, and her resistances to fire and heat.
She is also smaller than usual, 27 centimetres to be exact. Because imps are teeny little gremlins XD

My long-time friends will know that when I created Mira as an “Imp Dragon”, that it was just a to define her as a small dragon. So this was interesting for me, to actually have her as an imp and a dragon mashed together. It does explain her traits more, since imps are small, mischievous creatures, and Mirage the character is a mischievous thief.

I was using both Midna (tLoZ:TP), and Feral Imp (Yu-Gi-Oh!) as references to make Imp Point. This is why she is fluffy (or fuzzy) rather than scaly, I took the fuzz from Feral Imp.
Random trivia: Feral Imp is actually where I adopted the “Imp” for Imp Dragon.

Mirage the Imp Dragon (Imp form) is owned by me.
Bepo is owned by Eiichiro Oda.
