I'll admit at first that I did not Scraggy at first. He seemed like a rude idiot to me and I never cared for the pants lizard in the game. But overtime I learned of how awesome Scraggy is, and he has become one of my favorite parts of the Unova saga. His developement from baby to mostly capable battler, his bromance with Scraggy, and how he interacts with other characters like Ash and the wild Scraggy made me realize I was wrong to instantly reject Scraggamuffin (is that correct?) without getting to know him first. He is my favorite of Ash's Unova Pokemon, and my favorite Unova Pokemon owned by the main characters as well.
