In the Norse legend source material, readers can't really pin down Loki. A shapeshifter and trickster by heart and nature, he's just as likely to help his fellow Norse gods as he is to stab them in the back, figuratively and literally. While the Marvel comics Loki was initially a straight-up villain, he has become far more complex as of late, and the Loki title card reflects this.
Recently, Empire managed to interview Loki himself — well, his actor Tom Hiddleston, but who's to say Hiddleston isn't actually Loki in disguise? — and he stated that the show's unique shapeshifting title represents the character at his core. Hiddleston explained, "The font of how Loki is spelled out seems to keep changing shape. Loki is the quintessential shapeshifter. His mercurial nature is that you don't know whether, across the MCU, he's a hero or a villain or an anti-hero. You don't know whether you can trust him."
Moreover, since the title doesn't settle on a font identity in order to create a unique logo, the show will likewise play with the notion of identity. According to Hiddleston, a major theme will revolve around "integrating the disparate fragments of the many selves that [Loki] can be, and perhaps the many selves that we are."
For audiences who hope the Loki show will once and for all answer just who Loki is and where his loyalties lie, Hiddleston and the title card might have implied that the question is the answer.
