Fuzz

Fuzz is usually very excitable, typically very kind and understanding to just about anybody. he oftentimes likes to listen and is almost always the first one to come running if someone needs help.He’s usually an optimist and has very high empathy. He’s also very cuddly in general, expect random cuddle puddles if you’re friends with him.

Fuzz was created originally with one purpose. Emotional support. Whilst his sentience was limited, he was able to wander wherever he wanted. He typically stayed in the therapy wing of the building he was assigned to, but also wandered and acted as emotional support to those getting treatment in all wings of the building. Despite the lack of complete sentience, he had his own room, which was connected to the break room. If he's ever having a bad day, you'll probably find him there. 

When Fuzz awoke in the post-apocalyptic world, he first searched around the building. With nothing but bodies around, and parts of the building destroyed including the therapy wing, he didn't leave his room for a few years. When Spark found him was the first time he ever got emotional support, even if Spark was ridiculously bad at it, though the engineer was able to convince Fuzz to keep moving. Spark was able to remove the line of code keeping him from complete sentience, and now he makes it his life mission to meet others and learn about their stories and the world around them. He still stays around the hospital, and always somehow ends up back in that somehow perfectly intact room, but now he has friends to drag him out of it.
