Odd /äd/ 1. different from what is usual or expected; strange. Riverdale is an odd town. It's full of strange people with strange talents. When Veronica Lodge, an odd outsider, shows up to Riverdale no one can keep their eyes off her. Especially not Archie Andrews. He has the answers to her odd powers but is she willing to ask. Surely something odd will get in the way of their perfect lives.
