Well, I didn't say that he was the only choice, since I don't know who else you're plannng to use. Also, Loki's characterization changed over time. In the earlier stories, he was the anti-hero trickster. in later stories, he became more openly evil (most notably, arranging the death of Balder) until he finally led the giants into the Ragnarok battle.
