I got a powerpack, but some of the bad guys don't apply to me. I see where I can add new ones, but can I delete the ones I don't like?
You sure can! Click on “View” next to the bad guy you want to delete, and then click on the “delete” link under the “I battled this” button. :)
Yes. Click "View" for each bad guy and the delete button will be under the "I battled this!" button
