Any one anyone, who like Pony as well as Transformers...
Here is a perfect fusion. (not really)

A pony called Soundwave.
with his pet as much as Fluttershy in her treehouse.
Savage the cat, laserbeak the sparrow and ratbat the... bat. :)
He carrying his pet in his portable bag that also shoot Soundblast.

The idea just brainstorming of the show itself.
1. i saw a blue "brony" that has the color Like soundwave. :)_
2. FLuttershy`s various of animal she tend.
3. the bags that the pony carry or travel with.

a spark happen seeing this things.
