Well, first of all, the characters are so well - known. Garfield is a beloved character, and Arlene adds an interesting dynamic to the relationship. In fanfiction, authors can explore different aspects of their relationship that we don't see in the original. For example, they can show how Arlene might react to Garfield's crazy ideas or how Garfield might change a bit to be more appealing to Arlene. Also, the humor that is often associated with Garfield can be incorporated into their relationship stories, making them both funny and heartwarming.
One great Garfield x Arlene fanfiction is 'A Day in the Park'. It beautifully depicts their relationship with Garfield trying to impress Arlene in his own clumsy way. Another is 'Arlene's Surprise' which shows how Garfield plans a special day for Arlene.
Garfield might be a product of some strange experiment in the Mass Effect universe. He could have been created by Cerberus as an attempt to create a being with a carefree attitude in the face of danger. Instead of being a super - soldier like Shepard, Garfield is just there to enjoy life. But his presence starts to change the way the crew on the Normandy thinks about things. His simple pleasures, like napping and eating, could make the more battle - hardened crew members realize that there's more to life than just fighting the Reapers.

Another common theme is adventure. The reader and Andrew might go on some exciting adventures together, like traveling to a far - off place or exploring a mysterious location.
