OK, I've came up with one idea. Or even two. This is about White Zetsus and their abilities. All of us know, that their bodies are made of Hashi's cells, thus most of their abilities and even the aspects of their body are somehow related to the plants theme, right? But there's this ability, Substitute Technique, which can hardly be associated with the vegetation. So where did it come out from? I assume that the reasons for it's existence at all can be found in the WZ history and origins. We also know from BZ that once they were humans, yet were trapped into Kaguya's Infinite Tsukuyomi and became kinda the shells of their true self. And Substitute Jutsu allows them to gain any self they touch - every WZ soldier lost the identity long ago, he's nobody, that's why he can transform into anybody.

Besides, although Guruguru is a unique case, he still has a representation of this trait - he could encase anybody he wished to. And now I even see a link between this and Obito calling himself nobody - once he weared Guruguru as a suit and gained his nobody nature, i.e. the same mask as the Guruguru's face, which allowed Obito to be anybody we wished to as well, shifting names, identities and judgment with ease.
