Biography
His entire backstory was similar to Rick of C-137, except he didn't come from a dimension where his original family died, and really did leave his family for 20 years before returning.

In the events of "Forgetting Sarick Mortshall", he chose Two Crows over Morty, and completely forgot about the boy, living a new life as an anime protagonist, fighting enemies and making friends.
