In 'glee', characters like Rachel Berry would likely be a main character. She's very outspoken and talented, so she could have some great interactions with the Irwins. And from the Irwin side, Bindi or Terri Irwin could be main characters as they are well - known in the Irwin family.
Another character from 'glee' who could be a main character is Kurt Hummel. He has a very distinct personality and style. When combined with the Irwins, he could add a unique flavor to the story. And of course, Steve Irwin (even in a fanfiction, his spirit could be a big part) could be a main character as his legacy is so important to the Irwin family.
Perhaps there could be a story where the 'glee' club members visit the Irwin's zoo. They get to see all the amazing animals and end up learning a lot about wildlife. In the process, they might also teach the Irwins some new music and performance styles.
Most probably, the Irwin family are the main characters. Given their fame in dealing with crocodiles and wildlife in general, it's them who would be at the heart of this 'Crocodile Love Story'. They are the ones who have a special bond with these reptiles, and so they would be the main focus in the story.
The 'Crikey it's the Irwins Crocodile Love Story' might be a tale that showcases the Irwins' passion for crocodiles. The Irwins, who are famous for their wildlife work, likely have many stories to tell about crocodiles. It could be about how they've dedicated their lives to understanding crocodile behavior. They might share stories of close encounters with crocodiles in the wild, and how they've used these experiences to promote conservation. It could also involve their efforts in rehabilitating injured crocodiles and releasing them back into the wild. Their love for crocodiles is a big part of their identity and their contribution to the world of wildlife conservation.
I think Quinn and Black Widow would be an interesting pair. Quinn is used to being in a position of power and popularity in the Glee club, and Black Widow is a strong female character in the Avengers. They could have some really cool exchanges about strength and femininity.
In my opinion, it would probably be Kurt from Glee and Darren Criss (who is associated with Starkid). Kurt is very fashion - forward and has a strong passion for performing arts. Darren Criss is known for his incredible talent in Starkid productions. Their shared love for music and the stage would likely draw them together first.
I think Santana and Brittany would also be important characters. They are very influential within the group. Santana's sassy attitude and strong vocals would make her a force to be reckoned with when the kids take charge. Brittany, with her unique dancing skills and her own brand of charm, could contribute in her own special way. Maybe they take charge of creating a really cool dance routine for the glee club's next big show.
The main characters would include Kurt Hummel. He would probably be in charge of the decorations, making the dinner area look fabulous. Mercedes Jones would be there, bringing her amazing voice and her big heart. Puck would also be involved, maybe causing a little bit of chaos at the dinner table but in a fun way. And Quinn Fabray, who might be reflecting on how much her life has changed since last Christmas.
There's a chance that the fanfiction might introduce an original character who becomes an important part of the Glee club. This new character could interact with the existing ones and change the dynamics, which would be in line with the 'glad you came' theme as they bring something new to the group.
Artie could be a surprising survivor. Despite his wheelchair, he's very intelligent. In a Hunger Games crossover, he could use his brains to outsmart the other tributes. He might be able to set up traps or figure out the best hiding places. Also, the other characters might underestimate him because of his disability, which could work to his advantage.
Mr. Schuester from Glee could be a main character too. He could be the one who tries to bring the two groups together, seeing the potential in the Glee club and Supergirl working as a team. His role as a mentor in Glee could be extended to Supergirl as she tries to navigate the more complex aspects of human relationships and teamwork in this crossover fanfiction.
