Jacob "Jake" Grimm II is a member of the Grimm family, who was born in 1978. Named after his great-great-great-great-uncle Jacob Grimm, he is the younger brother of Henry Grimm, being the youngest son of Relda Grimm and Basil Grimm. He is a paternal uncle to the protagonists of the series, Sabrina and Daphne Grimm, who call him "Uncle Jake." First introduced in The Problem Child, Jake appears to be a care-free man who collects ; however, like his niece, he was touched or 'addicted' to magic until Sabrina wished (with the power of the Blue Fairy) that he always knew what the power his family and knowledge already gave him.
