Thor Odinson
Thor is Loki's older brother. They have a very complicated relationship, and they always have. Loki has always wanted to be nothing more than Thor's equal, and he has tried many times over the years to prove that he is such. What he doesn't realize, however, is that Thor has always seem them as equals, and that he's had the love and adoration he's longed for all along, and just been too bitter over Odin's favoring of Thor to notice it. They are currently on speaking terms again, but Loki doubts it will last for long.
