Orko is the heroic court magician. He is a character appearing in the Turtles of Grayskull comic series.
Turtles of Grayskull[]
The Turtles, having chosen to remain on the planet Eternia, wish to communicate with Splinter on Earth. Orko weaves a magic spell which opens a window, allowing the Turtles to speak to Splinter and April in the lair. After Michelangelo finishes telling their story, Orko reminds them that it's time for the gathering and that Man-At-Arms is very into punctuality. Donatello asks Orko to wait while he poses a question to his father. Before Splinter can answer, Orko closes the window.
Orko is among the Masters of the Universe, Turtles, and their allies who join the major battle against the forces of evil. Turtles of Grayskull issue 1
