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 heads, 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.
Being a Wisp, Yacker is peaceful, helpful, and friendly of nature, and he enjoys spending his time with others.
Assuming that Yacker is like the other Wisps, he is not much for fighting, but he is still a brave and good-hearted soul who does not approve of amoral behavior.
Powers and abilities
Yacker is able to levitate in midair at will, which serves as his main method of transportation.
Being a Wisp, Yacker is able to generate and store his own unique variant of a powerful energy inside his own body, which he can pass on a fraction of by phasing into the recipient.
