Thor
Thor is one of the most popular characters of the Marvel Universe. He has appeared not only in his trilogy, but also in 4 of The Avengers movies. Actor Chris Hemsworth brought the superhero son of Odin to life since 2011 and he’s clearly one of the characters that has changed looks many times along the saga. He’s cut his hair short, then let it grow back, dyed his hair, and he even gained muscle.
S.H.I.E.L.D. stands for Strategic Homeland Intervention, Enforcement, and Logistics Division,
not "Supreme Headquarters, International Espionage, Law-Enforcement Division" as is claimed here. Get it right, man...
