Nebula as seen in Episode 12, in his usual cat-ear form
|First Appearance||Episode 12|
Black Nebula is a supporting character in Sgt Frog Abridged. He is an amorphous alien that sits atop his daughter Alisa's head in the form of cat ears. He comes from a race of aliens that eat other aliens; he brought Alisa to life from a doll in order to help him find his food. He can transform into any shape, be it tentacles, a scythe, or a chair.
He generally speaks in a fatherly, firm but calm voice to Alisa and others. His voice is Thorn's normal speaking voice processed through delay and flange, then pitch-shifted down a step.
