Eco is one of the robots inside the "island". He is the head computer in the biospheres.
Appearance[]
Eco is a very large, grey, amorphous robot. He lacks anything resembling a human face, but has a circular screen that produces a vibrating circle when he speaks. His "chest" consists of a panel that displays information about the predator-prey simulation.
Personality[]
Like Tobor, Eco has very little in the way of a personality. He has only one job: guard the biosphere; and don't let anything in or out. Such a job doesn't require a personality.
