Bio: Rover is one of the last Sentinels on Earth-15104. After 150 years of life, he has apparently become almost sentient.
Rover is a Sentinel who has gained a minimal level of sentience and who serves Tom Skylark. The circumstances are unknown, but Rover raised and fed Tom from the time he was a baby and remained with him from that point onward.
According to E.V.A., Rover loves Tom. Rover only ever said the word "Destroy". When Rover though Tom was in love with E.V.A., it sacrificed its 'life' and for the first time uttered another word: "Tom".
