Hundred-Eyes Dragon is the signature Synchro monster of Kalin Kessler, a Dark Signer in Yu-Gi-Oh! 5D's, and a key card in his Infernity deck. The monster later appeared in Yu-Gi-Oh! Duel Links, where its summon gained a distinct audio cue that players recognised from duels. Its many eyes and copying ability made it memorable among fans of the series, and clips of its summon are still shared by duelists who recreate classic 5D's moments, post deck showcases, or add a dark, villainous flavour to their edits.
