Beta Suiter does not have an official name, nor does he have a nickname. While Beta Suiter is suggested to be male their gender is not explicitly defined, suggesting they could also be female.

The Beta Suiter follows Krone after he used the Alpha suit to make a Time-Jump. The Beta Suiter's use of the Beta Suit which is the major defining mechanic of the game.
Although initially he seems to be a scientist working on the time travel suits later cut scenes suggest he is an agent of a unknown agency assigned to eliminate Dr Krone if he attempts a time jump.
