Oddball is one of Dottie and Dipstick's puppies together with Domino and Little Dipper in 102 Dalmatians. She is the only Dalmatian without spots in the whole franchise. She is also one of the main protagonists of 102 Dalmatians: Puppies to the Rescue.
It's like Best and Worst of Villains, but for fictional heroes.
BTW, if anyone copies this (which might be likely since I've seen a few duplicate casts in categories like this one), this is the original.
