One common theme is the exploration of nature and its power. Since Swamp Thing is closely related to nature, OCs often find themselves immersed in the natural world and learning from it. Another theme is the idea of the outsider. Swamp Thing is an outsider in human society, and OCs are often outsiders in some way too, whether it's being new to the swamp area or having unique abilities that set them apart. And of course, there's the theme of friendship or a deeper relationship developing between the two characters.
There are several. 'Swamp Thing's Unlikely Friend' is a fanfic where the OC is a scientist who initially wants to study Swamp Thing but ends up forming a deep bond. 'The Swamp's Secret' features an OC who has a hidden past and gets involved with Swamp Thing while exploring the mysteries of the swamp. And 'Swamp Thing and the Mysterious Stranger' has an OC that appears in the swamp one day, and Swamp Thing has to figure out if they are a friend or a foe.
