In a fanfiction, a big challenge for Lightning McQueen and Doc's love story could be their public image. Lightning is a famous racer, and Doc has his own reputation in Radiator Springs. If they get into a relationship, they might face a lot of scrutiny from the media (if cars had media). Their fans might have different expectations of them. Also, Doc might be worried about holding Lightning back from his racing career, and Lightning might be afraid of changing Doc too much. These internal and external factors could create many obstacles for their love to thrive.
Lightning McQueen has always been a speed demon, but something changes when he meets Doc. Doc is different, with his gruff exterior but kind heart. Lightning can't help but be drawn to him. The moment he realizes he's in love is during a particularly tough race. Doc is on the sidelines, giving advice. Lightning hears his voice and suddenly feels a warmth inside. He then starts to court Doc in his own way. He shows off his new racing techniques, hoping to impress Doc. Doc, seeing Lightning's efforts, begins to see him in a new light too. Their relationship develops slowly but surely, like a classic car being restored with care.
Maybe Lightning McQueen decides to start a racing school in Radiator Springs in honor of Doc Hudson. He could use Doc's old training methods and stories to teach the new generation of cars. This would not only keep Doc's spirit alive but also help the town grow in a new way.
A fanfic about Lightning McQueen's crash in Cars 3 could involve his post - crash recovery. He might have to go through a long and difficult process of getting repaired. During this time, he starts to write a book about his racing experiences, which becomes really popular. This new - found fame as an author gives him a different perspective on his life. He realizes that he can still have an impact on the racing world, even if he can't race as he used to. So, he uses his book to promote safety and sportsmanship in racing, and eventually, he makes a comeback in a special exhibition race.
One great fanfiction idea could be that Doc Hudson, despite being in the afterlife, still manages to guide Lightning McQueen through some tough races. He appears to Lightning in his dreams and gives him advice on how to handle different track conditions and opponents.
Perhaps after the kiss, the other cars in Radiator Springs start to tease them a bit in a friendly way. Lightning McQueen might get a little embarrassed at first, but Sally just takes it all in stride. This could lead to some really fun and light - hearted moments in the fanfiction.
A possible plot is that there is a mystery in the Durt Racing world. Lightning McQueen hears about it and decides to investigate. As he delves deeper, he discovers that there is a conspiracy to disrupt the Durt Racing events. McQueen then teams up with some of the local Durt Racing heroes. They work together to expose the bad guys and save the Durt Racing community. During this adventure, McQueen learns a lot about loyalty and the importance of different racing cultures.
One possibility could be that they kiss after Lightning McQueen wins a big race. Sally is so proud of him that she can't help but give him a big kiss right there on the finish line. It's a moment of pure celebration and connection between the two characters.
A simple love story could be that Lightning McQueen and Sally gradually fall in love as they spend more time together in Radiator Springs. They start with small gestures like McQueen bringing Sally a bouquet of wildflowers he found on one of his drives.
One possible scenario in a fanfic could be that Lightning McQueen's crash in Cars 3 leads to a moment of self - reflection. He might start to question his racing abilities and his place in the racing world. This could then lead to him having to rebuild not just his physical car body but also his confidence. He could meet new characters during his recovery who help him see things from a different perspective and inspire him to come back stronger than ever.
There are many great fanfics in the Cars universe. A possible fanfic could be about Lightning McQueen joining a Durt Racing event. Maybe he faces new challenges and rivals there, and has to adapt his racing style. It could also involve his relationships with other characters during this special racing event.
