Larry Ketterlly was one-fourth owner of Phoenix, a holding corporation used to purchase major amounts of property along New Gotham's waterfront. Larry Ketterlly killed the other partners in the venture so that he could gain sole control, on behalf of Harley Quinn, the mastermind behind the scheme.
One might be able to mark an argument for classifying Larry Ketterlly as simply a variant of the classic Batman villain "Scarecrow" (a.k.a. Jonathan Crane). But because Larry Ketterlly has a different given name, we have created a separate record for him. He could be a new villain inspired by the original Scarecrow.
