"You can't stop it. The Bifrost will build until it rips Jotunheim apart."
"Why have you done this?"
"To prove to Father that I am a worthy son! When he wakes, I will have saved his life, I will have destroyed that race of monsters, and I will be true heir to the throne!"
Loki and Thor[src]

The Duel at the Rainbow Bridge was the final confrontation between Thor and Loki, where Thor fought his brother to prevent him from using the Bifrost Bridge in a plot to destroy Jotunheim, having to destroy the bridge itself to accomplish it.


"Now, if you'll excuse me, I need to destroy Jotunheim."
Loki to Thor[src]

Laufey and his Frost Giants arrive on Asgard

Loki learned that he was the son of the Frost Giant king Laufey, who abandoned him as a child to be found and raised by Odin, the king of the Asgardians. Since Thor was the "favorite son" of Asgard and destined to be its king, Loki felt rejected by both of his fathers. Loki invited Laufey to Asgard so he could kill Odin, who was incapacitated in his "Odinsleep," but Loki killed the Jotun King, doing something neither Odin or Thor would do.

Thor, in the Battle of Puente Antiguo, proved worthy of Mjølnir and to return to Asgard after his exile. He learned from Sif that Loki lied to him about their father's death.[4]


Loki attempts to kill his own brother Thor

"Loki, this is madness!"
"Is it madness? Is it? Is it? I don't know what happened on Earth to make you so soft! Don't tell me it was that woman? Oh, it was. Well, when we're done here, maybe I'll pay her a visit myself!"
Thor and Loki[src]

Loki activated the Bifrost to begin the destruction of Jotunheim by unleashing its full power. He explained that he only wanted to be Thor's equal in Odin's eyes, but now he desired the throne because he will have accomplished what no one else has done in destroying the Frost Giants. The two began to fight. As Loki fell onto the Rainbow Bridge, Thor placed Mjølnir on his chest, making him unable to move. Loki taunted Thor that what he has set into motion was unstoppable. Meanwhile, Odin awoke from the Odinsleep.

Loki falls to his apparent death

Thor realized that Loki spoke the truth and began to hammer the Rainbow Bridge with Mjølnir. Loki told Thor that if the Rainbow Bridge was destroyed, Thor would never see Jane Foster again. Thor continued to pound the bridge until it collapsed. Both fell over the side, only to be caught by Odin. Loki told his adopted father that he did everything to impress him. Odin listened, but disappointment showed on his face. Loki decided to release his grip and fell into Yggdrasil itself.[4]


Odin uses dark energy to teleport Thor

"With the Bifrost gone, how much dark energy did the Allfather have to muster to conjure you here?"
Loki to Thor[src]

Loki was found by Thanos, who showed him the potential power of the Tesseract and gained Loki's servitude.[5]

When Thor sought to go to Earth because Loki was in Stuttgart causing a hostage situation,[5] Odin used dark energy to transport him.[6]

With the Bridge destroyed, Marauders took advantage of the Asgardians' lack of transportation and plundered Vanaheim and other worlds.[7] The damage to Jotunheim left a total of more than 200 dead.[8]

After the Battle of New York, Thor returned with the Tesseract. Heimdall and him used the Tesseract to repair the Rainbow Bridge.[6]
