In Glee fanfiction, unicorns and angels can be portrayed in really creative ways. Sometimes, they might be used as symbols of purity or magic within the Glee universe. For example, an angel could be a guardian spirit for a character, guiding them through difficult times like auditions or relationship problems. Unicorns could represent something more fantastical and rare, perhaps a character's wildest dreams or hopes.
Another role is as a plot device. Maybe a character is in a coma and they encounter an angel in their dream world. The angel gives them a message that is crucial for them to wake up and face a big performance. Unicorns could be part of a hidden world that a character discovers, which then becomes a central part of the fanfiction's plot as they try to bring elements of that world into the Glee club's reality.
Yes. It could be a magical story. The Lion, a symbol of strength and courage in the real world, could meet the Unicorn, a symbol of purity and magic. Maybe they start as enemies but then become friends as they face a common threat.
Unicorns are often made into comics through creative imagination and artistic skills. Artists envision their unique characteristics and adventures and then bring them to life on the page.
