Rosechu (pronounced "rose'chu" ([ˈro:ztʃu]) in canon;[2] ro'-za-chu ([ˈrozətʃu]) in the Audiobooks) is the second Electric Hedgehog Pokémon created by Chris, and the girlfriend-turned-wife of Sonichu.

As the primary female character in the Sonichu universe, she represents Chris's idea of a perfect woman, which unsurprisingly amounts to a bleating wall-eyed semen receptacle with no personality. Rosechu's interests include kissing Sonichu, shopping, gossiping, sucking Sonichu's pickle, posting nude photos of herself on the Internet to uphold her reputation, and stripping for Women's rights. Chris will occasionally have Rosechu refer to him as "father" (or more likely "papa"), just like Sonichu. Rosechu is extremely defensive about rumors that she has a penis.
