I do like Scratch, mostly because he sort of made it into the Archie Adventures comics under the name, "Hallowcat." Plus, his design looks pretty cool when its drawn a certain way:

But, yeah, some of those random mutants in the toy line just felt so underdeveloped that even the most die-hard fans didn't have the urge to buy them back in the day.
