Onyx and Opal are minor characters who appear in the Disney Junior animated series Sofia the First, with Kevin Schon as Onyx and Grey DeLisle as Opal. They are two griffins who live in the castle jewel room along with their son Jasper.
Role in the series
They first appear with their son in "The Amulet of Avalor", when Roland takes Sofia and Amber to the castle jewel room. Roland tells Sofia that they guard the treasure because griffins love shiny things. They take their job of guarding the jewels very seriously.
They reappear in "Minimus is Missing" to help Sofia, James and Amber recover the missing flying horses. It is revealed that despite their fierce appearance, they are actually very gentle creatures, who are happy to help Sofia, whenever she asks. Opal is very tolerant with Amber, who did not know how to fly, and would accidentally interfere with her flying. Onyx tries to be a good example for his son, such as trying to teach him to sit still and learn what the task at hand is. Both love Jasper very much, though they both agreed they never would get him back into the jewel room after this adventure.
