Principal Reginald Skarr is a minor character in Powerpuff Girls Doujinshi and Grim Tales. He is the principal of Megaville Elementary and appears in a few pages of Chapter 7. He makes a cameo in Grim Tales in one panel of Chapter 2. He originates from the Cartoon Network show, The Grim Adventures of Billy & Mandy.
In Grim Tales: From Down Below he appeared in the alternate page of Coop? where he was standing in his gardening clothes under the command of Mandy, in the real page he was replaced by Yogi Bear and Boo-Boo.
The most notable thing about Skarr is that he has been blinded in his left eye, by unknown circumstances. He has many weapons and his old military uniform in his home as a memento of his time working for Hector Con Carne. He now is a principle and thus wears a neat uniform. He used to wear hats because of his baldness but now doesn't anymore.
Reginald Peter Skarr is an retired general and Billy's one eyed freak of a neighbour who is very protective of his garden. He used to work for Hector Con Carne in Evil Con Carne, but quit. He hates Billy very much, is afraid of Mandy and wants Grim's supernatural scythe. He stole Grim's scythe once but thanks to Pud'n and Mindy, Grim got it back.
