Skrull's are an evil alien race which try to destroy the Kree empire and invade the Earth. Skrull's first appear in My Neighbour Was A Skrull.
Skrull's have a yellow/green scaly skin with red pupils and huge elf-like ears. All Skrull's have a colour scheme of purple and dark blue for clothing.
Most Skrull's are cunning, smart and very secretive but mostly they are very persuasive when in a appearance of an object like a cow or person.
