8. King Thor
2011’s Thor teased his ascension to the throne, but what happens when he actually takes over the realm of Asgard? The pressure of ruling his kingdom eventually proves to be too much for him and the military soon decides to take action. Iron Man – then Secretary of Defence – dons special armour known as the “Thorbuster” suit (which even allows him to deflect attacks from Mjolnir), but is still unable to defeat the God of Thunder. While Thor eventually comes to his senses, his relationship with his fellow Avengers is damaged beyond repair and he doesn’t reunite with them until just before his apparent death during Ragnarok.
