Dr. Bluestein is an alien of an unknown race. He is first seen in a flashback in "Chapter 1". He is voiced by John DiMaggio who voices Bender from Futurama.
Appearance[]
Bluestein is a humanoid alien with a single, yellow eye. He has large teeth, that seemingly prevent him from fully closing his mouth, since he always bares them.
Background[]
Five years prior to the events of the series, he and Derek were chasing Gary Goodspeed through a rainy night in New York City. They wanted a diamond Gary had, and which they claimed to be theirs. Gary evaded them by fleeing into a bar, where he first met Quinn Ergon.
Alternate versions[]
Dr. Bluestein from Nightfall's timeline.
In "The First Times They Met", it is revealed that in Nightfall's timeline, Bluestein was a member of the Infinity Guard and good friends with her timeline's Gary Goodspeed.
