I'm working on a character that is a mixture of what I found interesting about cybernewtypes from Gundam (admittedly not a ton), Clanners from BattleTech (less the society obsessed with bad tactics and more a upbringing in a very rigid caste system), the Bene Tleilax from Dune (more the whole Ghola / vat born created from centuries old genes vibes than shapeshifting peeps) and tossing in some sweet Undertail psy vibes.
