Let's talk this out a bit, mostly because we had precisely zero discussion of Nimbasa's character up until now.
There's a ton of overlap between Nimbasa's character and Herr Brackhaus' PC. Nimbasa has some cyberlegs (that probably could benefit from some Strength and Agility enhancements) with hydraulic jacks, but otherwise has the same skillset as Herr. Perhaps the overlap makes sense if we are a sneaky crew, but I want to make sure CraterShip is comfortable with it and feels like the group can accommodate both.
If we (or, more specifically, CraterShip) decide that some diversification would be in our better interests, then I might point out our current lack of fire support. Again, perhaps this makes sense for a stealth crew, but Herr is our current heavy hitter with about a dozen dice in Automatics. Rednblack and Raiderjoseph both use Pistols, Raider with about 4 dice. I can cast a few spells and summon spirits, but overall we're light on firepower.
Nimbasa mentioned a concept for a Yakuza assassin, which could be interesting and a good fit that also diversifies our skill base somewhat. Alternatively, we could rework Rabbit a bit to emphasize those cyberlegs and jumping, kicking, and parkouring.
