Rex. He was a police doggo and was later turned into a cyberdoggo. After the bombs fell, he became a doggo for a warlord although he was lost in battle. A prospector found him and he was sold to an Elvis Presley cosplayer. Unfortunately, his brain is starting to give away so Elvis Presley tasked a deranged and possibly mentally handicapped mail man to find a brain replacement for him. Rex hates rats and also hats, dunno why he hates hats. Maybe it’s because it rhymes with rats? Anyways, Rex good cyberdoggo.
