"Legion recently became intrigued by my muscles and he wanted to test how it feels like having them. And so I gave him a sample to apply to himself and boy did it help. It fixed up the hole he had gotten during a battle quite some time ago and gave him a nice and strong new body. And even more surprising is that he actually got a little more "human" so to speak. He now refers to himself as I, me and such, the type of thing you would expect from a non hivemind being. And he's really happy about it. It has given him the feeling of having a soul."
This was done as a request by  24Momochi here on FA.
