Jeremy Johnson

Jeremy Johnson is this hippe dude who Candace is always stalking. Eventually, they do get together, but I forget if they stay together or if it's short-lived. But canonically, they did date/are married. Jeremy is somehow related to (don't ask how, StarClan will get angry if you do) Oakheart, the super dead hippie cat that Tiggyclaw killed, and the two of them always complain about pollution and stuff, especially ShadowClan and Dr. Doof, who Oakheart is disgusted by because Dr. Doof is always trying to PWN the citizens of Danville, Virginia, along with all the kittehs who live there.
Jeremy Johnson and countless other characters from other universes crossed into the Warrior Cats Universe during the Great Universe Clash. Jeremy joined RiverClan, and was named Greenfur.
