Our Battlebabe became a Skinner as part of her attempts to win her old (NPC) lover back. She still feels very much like the same character, to be honest--just now she goes around calling out people's names to the psychic maelstrom when she gets in trouble, or just feels like it.
Last session, our Chopper lost control of his gang and became a Gunlugger. That felt very natural. The player said he'd been planning it for awhile.
Our Brainer is talking about becoming an Operator, which seems like a less obvious/natural choice. I'm excited about it.
Our Hocus is thinking, possibly, about becoming a Hardholder.
Our Angel just set up an infirmary inside a ghost tree. Who knows what's going to happen there.
