When Pokemon are in their base forms, most of them look cute and cuddly, such as the starter Pokemon and beginning birds and rodents. Another example to add would be the Starly line. When Starly evolves into Staravia, and later into Staraptor, it gains hawk-like characteristics in addition to the starling characteristics. Also: Glameow and Purugly. Glameow is based on a house cat but Purugly is based on a tiger cat.
