Well, Pumbaa in 'The Lion King' is quite an interesting character. He and Timon are like a duo. They come across young Simba who is all alone and lost. Pumbaa's simple - mindedness and his big heart are what make him special. His flatulence is also a bit of a comical aspect of his character. He teaches Simba to have a more laid - back view of life with his 'Hakuna Matata' philosophy, which basically means no worries.
Friendship is a common theme. Since Timon and Pumbaa are known for their strong bond, in crossovers, they often form new friendships or strengthen existing ones with characters from other universes.
I can't really speak to the main themes in such fanfics as I haven't come across many. But perhaps themes of friendship deepening into something more, acceptance of different forms of love, and exploring a non - traditional relationship within the context of their shared adventures could be possible themes.
There might be some, but it could be hard to find. Since Timon and Pumbaa are characters from a family - friendly franchise, this kind of fanfic might not be as widespread. You may have to dig deep into fanfic communities or specific forums where people might be sharing or discussing this type of non - mainstream interpretation of their relationship.
In a Timon and Shenzi 'Lion King' lemon fanfic, the author might play with the characters' personalities. Timon is known for his witty and carefree nature, while Shenzi is a bit more menacing. Combining them in a fanfic could lead to some really unique scenarios. For example, they could team up to outwit other characters in the Pride Lands, or they might find themselves in a situation where they have to rely on each other's strengths in a completely new way.
I'm not sure specifically as I haven't read that exact fanfic. But generally, in a Lion King fanfic, it might be about the adventures of Timon and a character named Chenzi within the Lion King universe. It could involve their interactions with other characters, new challenges they face, or unique interpretations of the story's themes.
One interesting 'Timon and Pumbaa' crossover fanfiction could be where they meet characters from 'The Lion King 2'. Maybe they help Kiara in some way, adding their unique humor and wisdom to her journey.
A theme of friendship - turned - more - than - friendship might be common. They start as just characters who interact in the Lion King world, but in fanfiction, their relationship can develop into something deeper, like a romantic relationship. Also, the theme of acceptance, as they accept each other's quirks and differences in these stories.
One possible plot could be that Timon gets lost in the outlands where Shenzi lives. Shenzi, instead of seeing him as an enemy, is intrigued by his different ways. They start to interact more and more, and a strange sort of friendship - with a bit of a 'lemon' undertone of attraction - begins to form. They might then have to face the challenges of their different worlds coming together, like how Timon's friends in the Pride Lands would react and how Shenzi's hyena pack would view her newfound relationship with Timon.
