Yacker is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. He is a Wisp that Sonic and Tails met and befriended during their visit at Dr. Eggman's interstellar amusement park.
Yacker's basic shape is that of a sphere with three tentacles, two of which are used as arms. He has one pink eye in the center of his head, and two very alien-like antennae on top of his head. Yacker's most distinguishing feature that sets him apart from the other White Wisps however, is a strand of curly blue "hair" on his head between his antennae.
Yacker was among the Wisps whose planet got captured by Dr. Eggman, who sought to harness the Wisps' power for a special supply of fuel. While on the run from Eggman's henchman robots in Dr. Eggman's Incredible Interstellar Amusement Park however, Yacker was saved by Sonic the Hedgehog, who managed to drive off Yacker's pursuers after taking out most of them with a display of the Cyan Wisps' power. When Yacker tried communicating with Sonic and his sidekick Tails in his native language, the latter turned their handheld into a translator, allowing them to understand Yacker, who told them of Dr. Eggman's plot. With Sonic and Tails promising to help him, Yacker and his fellow Wisp headed out with Sonic to stop Eggman.
Yacker is a talkative, but friendly and playful Wisp.
