"Right here, His name is Scampers."
-Yo, Digital Pet Cemetery

Yo is a character in Fanboy and Chum Chum.
Yo n lupe


Yo is a Japanese-American girl who has a big attraction to Chum Chum, even though Fanboy does not appreciate it. She is sweet and fun, and ready for anything. Nothing about her background has been mentioned in the series.


Yo is sweet, gentle, and is a collector of cute things. She owns Yamaguchi digital pets, one which is named Scampers. She thinks that Chum Chum is adorable, and "Chum Chummy". She even tries to steal him sometimes, which greatly annoys Fanboy. Yo is also known to be a talented prankster, dominating Fanboy whenever Prank Day comes.

Yo is usually in a good mood, but gets angry whenever Fanboy takes Chum Chum away, or other reasons. She usually acts as an antagonist toward Fanboy when he tries to take back Chum Chum, although she feels sorry for him a lot.
