the Guardian
He’s a white colored teletubby wearing a cow-print top hat. He’s known as an investigator, smart and very much intelligent, slightly less than Lenny

Lenny is a humanoid covered in dark blue fur with his face, including the inside of his large ears, depicted to have caucasian skin. He is wearing glasses and prefers to hold a knife at all times. He does not have an antenna.

From what little is seen of him, Lenny is impulsive and easily irritated, judging by the way he maniacally kicks faulty equipment or hits a peer for stealing his knife. On the other hand, he also seems to have more knowledge than the other characters, as he is recommended by the other soldiers to learn more about the origins of the infection and the Guardian's statements.

His bluish colour and workplace suggests that he may be a leading member of the Workers.
