O ícone do Persona pode ser alterado, sim. Eles têm uma persona que segue as mesmas regras das personas "normais":
A persona is a firmware program built into the device’s hardware that you use to interact with the Matrix, in AR and in VR. It allows you to perceive the digital world and projects your icon (or icons) into nodes. Without a persona, you would be unable to access the Matrix. Even technomancers have a (living) persona.
Todas as pessoas têm ícones:
Your persona is represented by an icon in the Matrix, as are your running programs, files, agents, IC, links to nodes, etc.
E ícones podem ser modificados através do ícone Alter / Swap, que não é específico para hackers, e disponível para Technomancers também:
Alter/Swap Icon (System)
You change a detail of an icon representing your persona or one of the programs, files, or nodes you own, or switch the icon to a pre-rendered icon you have stored.
