What If.. . Loki Was Worthy?

So many worlds, so little time. Infinite possibilities, creating infinite realities. Long have I watched the trickster god sow chaos. But...what if Loki saved Asgard from Tony Stark's revenge?
Thor - Son of Odin, God of Thunder, wielder of the hammer Mjolnir - is dead. And Loki is responsible.
It was only meant to be a joke - tampering with the Destroyer, changing Thor's course to Midgard - a bit of mischief with a chance of maiming. But Loki's harmless prank spiraled out of control, unleashing death and destruction on New York City and the heroes sworn to protect it. The city was saved, but at the cost of Thor's life.
Furious and heartbroken, the All-Father banishes Loki to Earth for his crime. Loki finds himself in a realm of boxed wine, instant noodles, and some sort of regional performance troupe known as the "Buffalo Bills." It's a meager existence, far from Asgard's grand courts, but he finds his new friend, Brian the Gecko, a much more engaging companion than the sycophants back home. A true meeting of the minds. Loki is the God of Mischief - but he knows, deep down, that he never truly deserved to stand next to their father's golden child Thor, as two true sons of Odin.
Yet, he cannot even endure his exile in peaceful isolation. A Valkyrie - Hel-bent on carrying out her oath to Thor - barges into his trailer-home with his brother's final words from the beyond: a plea to find a certain Dr. Jane Foster and pass on Mjolnir to its rightful heir.
While Loki struggles to fulfil his brother's last request, the far-reaching consequences of his fatal prank return to haunt him. Blinded by grief from those he lost in the chaos wrought by Asgard, Iron Man vows revenge on those who consider themselves gods. Determined to protect the Earth from the might of this unpredictable alien power, he forges Asgard's own weaponry into a lethal suit of armor, set on eradicating any tether between their worlds. Consequences nbe damned. When Asgard looks to Loki for salvation, he must answer the question: Am I truly worthy?
