10 Worst Things Loki Has Ever Done To Thor
2. He Beat Thor
Loki's plans more often than not end in failure. However, in the series Loki, not only did the God of Mischief beat his brother, but he did it before the series even started.
The out of continuity story was set in a world where Loki was able to beat Thor and take control of Asgard. Loki ruled his kingdom with an iron fist (in that he was a tyrant, not that he used dodgy-looking kung fu) and he kept his brother, along with Sif, chained to a wall in his dungeons and would periodically visit them to gloat about his victory.
Despite having everything he ever wanted, it wasn't enough for Loki. The throne did nothing to stop him feeling unloved and he soon found his allies like Hela and Lorelei turning on him.
Eventually, the ghost of Balder shows Loki the truth. There are hundreds of alternate universes in which Thor and Loki have fought and, in every one, Thor ends up winning.
To try and prevent this, Loki decided to have Thor executed. However, he then changed his mind and decided to defy fate by freeing him instead. Unfortunately, Loki was too late and Thor had already escaped on his own. Enraged by his imprisonment, the God of Thunder used Mjolnir to crush his brother's skull.
