Dr. Starline the Platypus from the IDW Sonic the Hedgehog comic series is inspired by a glitch character from Knuckles' Chaotix - a silver, red and charcoal Knuckles recolor, known by fans as "Wechnia", but by the game itself as "**********", seemingly based on unused data for Tails. Starline's color scheme is taken directly from Wechnia, his name is a literal take on the name "**********", (or "star-line") the black streak in his fur resembles the red streaks all over Wechnia's fur, and the choice of a platypus seems to be inspired by how certain Wechnia sprites would make the bottom of his muzzle yellow and loosely resemble shading for the underside of a flat bill, alongside platypi being Australian like echidnas.
