First appearance: X-Men
Looks like: Um... a really cool professor.
Patrick Stewart as Professor X couldn't be anymore perfect. He absolutely kills it in tailored suits and awesome menswear looks. However, James McAvoy's younger take on the character in X-Men: First Class showed that a youthful Charles Xavier had serious amounts of style. From shawl collar cardigans to a color-blocked battlesuit, he looked really dope.
