Thor

The Avengers got extremely lucky when the godly Thor opted to join the team as part of their founding roster in September of 1963’s Avengers #1 – and he’s been an important member of the team almost ever since.

The Asgardian God of Thunder has immense power, which includes super-strength and durability, flight and various weather-based powers courtesy of his hammer Mjolnir – and they wouldn’t have won nearly as many of their battles without him.

Chris Hemsworth has played the part of the character on screen since 2011 – in which he debuted in his own solo movie. Since then, he’s been a member of the Avengers in both of their movies and has starred in a 2013 Thor sequel as well. His next appearance will be in 2017’s Thor: Ragnarok and he will undoubtedly be an important character in the Infinity War.
