Maybe you can get inspiration from some of those designs? For my current persona, the only version existing of a humanized version is a fun little FNAF Secruity Breach concept where my persona takes the role of Gregory but is named "Sally" and she's missing half an arm. Though if counting my last persona, Selareon, there also does exist a humanized version too but she eventually got her own character named "Starlynn" who would act as like the "Pokemon Trainer" for Selareon
