Rodrigo is a sandy bay alicorn with a brown curly mane and tail. His wings are pale yellow-green and similar in shape to those of a butterfly, while his whorled, almost spindly horn is a shiny gold. His hooves are a sparkling green.
He is festooned with ribbons - gold around his lower legs and green in his mane and tail. He seems to have a green, multi-strand belt around his body, clasped by a medallion. Around his neck is a green collar studded with gems.
As Rodrigo is an alicorn and has wings, he can naturally fly.
Rodrigo seems to be a quiet horse, judging by his inspirational saying.
"It's okay to be quiet. Not everything needs to be said out loud."
