I'm sorry I can't properly introduce myself, but I don't have a name anymore. (1.1.1)
It's hard to describe yourself if you don't have a name. If someone asked who you were, how would you describe yourself without using your name? I'm this guy, here. No, not him. Me—with the thumbs!

I am Perry Kelvin, a nine-year-old boy growing up in rural nowhere. (1.2.26)
Talk about an identity crisis. R starts to absorb Perry's memories and, in a way, starts to become him. By the end of the book, it's hard to tell the two apart. Which is creepy if you think about it for too long, so let's not.

Who are you? Let the memories dissolve. [...]
You're you again. You're no one. (1.2.43-1.2.44)
We can see why R gets so absorbed into Perry's memories (or the other way around, perhaps). As a zombie, he has no self-esteem or identity. He sees himself as no one.
