Well if it isn't another ability strip. How novel.
Actually, for a long time I've wanted to make something out of the Trace ability, while also giving Porygon some screentime. I did, however, never decide on an ability to run with. Then Craig emailed me his Rough Skin suggestion, and after throwing the idea back and forth, we reached a satisfying agreement, which we hope will please the rest of you lot too.
Any likelyness between this update and earlier strips is a complete coincidence and should be ignored entirely. Something that is also a complete coincidence is that both Porygon and Druddigon share colors and name endings, which too should be ignored entirely.
