Working with the Chitauri
Having been presumed dead on Asgard, Loki sent by the Other to conquer earth, Loki was granted an army of Chitauri. When the Tesseract activated while in the custody of S.H.I.E.L.D., Loki arrived through the portal and attacked the S.H.I.E.L.D. Agents, using his Sceptre to mind control several of the agents he knocked out. Loki was backed into the portal chamber by Nick Fury and Hawkeye, two agents of S.H.I.E.L.D., leading him to fight them with 12 projections of his image. After Fury and Hawkeye defeated these projections, Loki was able to take control of Hawkeye and Selvig, leaving with the Tesseract as the base began to explode. Despite some resistance from S.H.I.E.L.D. Forces, Loki and his minions were able to escape.
After conversing with the Other about the progress of their plan. Afterwards, Loki helped pose a distraction in Struttgart, Germany while Hawkeye helped extract Irridium for Selvig's portal to the Chitauri army. Here, Loki was confronted by Captain America and Iron Man, two of earth's heroes. Loki engaged the duo in combat, gaining backup through mind controlled agents and his powers of illusion, until the heroes were able to capture him. Upon being escorted to the Quinjet, however, Thor kidnapped Loki in an attempt to discuss affairs between his brother. However, this conversaion was cut short when Iron Man and Captan America pursued Thor, leaving the three to fight amongst themselves. After the three reconciled, they brought Loki onto the S.H.I.E.L.D. Helicarrier. 
Cosmic Brick Crisis
Plotting with Doom
Upon being imprisoned within The Raft, Loki plotting his revenge. Planned to use the legendary Power Cosmic to enhance his own mind control power to take over Galactus' mind and have him devour Earth and Asgard. To that end, Loki made a deal with Doctor Doom, if Doom could capture the Silver Surfer's board, the two would harness its power and Doom could destroy Galactus so Earth would worship him. As Doom's forces pursued the Surfer, Iron Man blasted the helicopter which shattered the board, and split its pieces across the globe.
Escape from the Raft
When the villains (and Stan Lee) escaped the vault, Loki's cell opened and he escaped while the heroes above ground fought the other escapees.
Heist of Avengers Tower
Going to Hydra with the stolen Arc reactor, Loki used their considerable resources to open a portal to Asgard so he could retrieve the Tesseract to use as power source on the "Doom Ray of Doom". Upon the base being infiltrated by Black Widow, Hawkeye and Human Torch, Loki blasted the three with his sceptre, knocking Black Widow and Hawkeye out. Loki then jumped into the portal, transporting him to Asgard.
Skirmish on Asgard
Going to Asgard, Loki made an alliance with the Frost Giants, encasing Asgard in ice. After Thor, Human Torch, Captain America and Wolverine arrived on Asgard to stop him, Loki presented them with various illusions before confronting them in the throne room, where he used the Mind Stone to take control of the Destroyer and controlling the Destroyer, he was beaten by Thor, Cap, Wolverine and Human Torch. The four were able to pull the Destroyer apart was pulled apart, forcing Loki resorted to his usual illusions, something Wolverine was able to bypass through his heightened senses. After the four defeated Loki in combat, Loki teleported away, leaving the Teseract behind.Reporting to Doom, that Wolverine took the Cube, Magneto was sent to retrieve it from the X-Mansion. 
Ambush on Latveria
While working in Latveria with Doom, the two were confronted by Nick Fury and the Fantastic Four. Loki was able to stop the five, however, by blasting the ceiling, causing rocks to fall on them. He and Doom then escaped together.
Battle on Asteroid M
When Asteroid M was fuelled and ready, Loki joined Magneto and Doom aboard. He and Doom abandoned Magneto after the heroes defeated him. The three then confronted Doom and Loki. Being supercharged by Loki's scepter, Doom blasted the three, knocking Iron Man and Thor back into the lower areas but failing to take out Spider-Man. Thing, Captain America and Storm arrived to help Spider-Man, prompting Doom and Loki to retreat to the upper levels and continue their work. Eventually, the team of heroes made it to Doom, where he held them off while Loki remained out of reach. When Doom was defeated, Loki revealed his grand plan to the heroes and used the Doom Ray on the arrived Galactus, having him destroy Asteroid M in the process.
Galactus' threat was so great that Earth's heroes and villains had to team up to stop him. While he made good use of Galactus' power, Galactus' own hunger proved his undoing as the hero-villain alliance fooled the Devourer of Worlds with a model of Earth, that concealed Hulk and Thor. The two powerhouses were able to defeat Galactus and send him through a wormhole, dragging Loki with him, trapped in space with Galactus, who wondered how Loki would taste. 
After Heimdall was kidnapped by the Frost Giants and Malekith, Thor and Loki were sent by Odin to retrieve him. After opening the drawbridge where Heimdall's cage was held, Malekith engaged them in combat. The brothers defeated Malekith and freed Heimdall from his prison, with Loki going back into the shadows as Thor took Heimdall back to Asgard.
