Mordred, the king who was long ago deposed for his unethical experiments in cybernetics, has been using the pseudonym "Binary Bard". He is stealing equipment and material to build robot creatures with which to rule the Poptropica solar system. His diabolical plan included kidnapping the Princess of Arturus.
His identity is only revealed when you reach his castle in a far galaxy, having withdrawn the Golden Key which controls the portal on the Secret Planetoid.

Mordred, the evil dude in Astro Knights Island who kidnapped the princess.

He says "bard".
The Binary Bard is Mordred.
You can't costumize him in Astro Knights Island or Super Villain Island but you might search the common rooms for someone with his face.
The Princess has been captured before the start of the quest on Astro Knights island, and is not seen until the final battle in the lair of the Binary Bard.
Since Mordred / Binary Bard only appears in the pre-recorded scenes of Astro Knights Island, you can't use the Costumizer. You may locate someone on the islands who copied the Bard when he was promoting the island in May 2009.
The Binary Bard is on the Giant Asteroid near coordinates X-8 Y-82. But you cannot reach him until all three planets have been defeated and you have all three space knights with you.
on astro knight you have to save the three knights and after that a they take you to a this place that takes you to binary bard lair
Back in 2009, you could costumize as the Binary Bard. So you could copy it from somebody who did.
The "Binary Bard" half-robot face is not currently in the Poptropica Store, but some users copied it when the "real" Binary Bard frequented the multiplayer rooms prior to the release of Astro Knights Island.
You can't costumize him in Astro Knights Island or Super Villain Island but you might search the common rooms for someone with his face.
