FAKE.

SCP Foundation Emergency Report: Item Number SCP-CN-xxxx "The Shapeshifter." In social settings, the Shapeshifter is an absolute chameleon -- they switch personality masks faster than you switch keyboard languages. One second they're in ride-or-die bestie mode, the next a boss walks in and they instantly toggle to dependable-model-employee mode; even the sheen and curl of their expression subtly recalibrates. You think you've made a friend who truly gets you? Wake up. You just got lucky enough to encounter a high-performance, expertly disguised android, that's all. Late at night, the Shapeshifter peels off their masks one by one, only to discover that underneath... it's empty. Those masks were the self all along.
