Thor & Loki: Blood Brothers is a four episode motion comic mini-series from Marvel Knights Animation released on iTunes in March 14, 2011. The story mainly focuses on a triumphant Loki, giving out his point of view, his reasons, also showing what happens after he achieves all his objectives.
In the first part, Karnilla has ordered Loki to kill Thor because of a deal Loki made with her for which he hesitates knowing that despite being ignored by most Asgardians; Thor was the only one to ever show brotherly love and treated him as family.
Second part shows Loki receiving insults from Sif who is now a prisoner in a cell next to Thor's. Loki believes Sif to be just as foul as he believes Odin is (for which he pointed out to her), for which Sif returns with disgust.
In part 3 of the series, he has a discussion with Balder, there Balder reveals that no incarnation of Loki has ever been Lord of Asgard and that this Loki will share a same fate (a surprise that leaves Loki in horror). Later, Loki meets his actual biological mother, Farbauti Laufeyson, for which he thought had been dead for so long ago.
Part 4 shows that Loki, instead of taking Thor's life, wants to rule along side his brother on Asgard. Whether this succeeds is unknown for it the last part ends in cliffhanger leaving Loki meeting Thor who has bursted out of his prison and smashes Loki with Mjolnir.
