With the recent casting of a few young X-Men: Apocalypse characters, fans continue to wonder who else might make an appearance in the upcoming film.

Though the franchise has explored many of the Marvel characters over the years, some favorite have still yet to make their big screen debut. Others have been mishandled, causing writers to rethink and restristribute those characters in the Marvel reboots.  

Perhaps the biggest omission thus far has been that of Jubilee, who played an important role in both the comics and the cartoon television series. Though she did have brief cameos in the original X-Men films, the role was so small that it involved two actresses (Katrina Florence and Kea Wong) who were primarily used as mutant filler at the school.

Jubilee would be too young to really existent in the upcoming film, which takes place before she was a teenager, but there are a few compelling reasons why an exception could be made. Jubilee's power to project electricity with her hands could come in handy. As an Asian character she could also help provite diversity for the cast, which has primarily used people of color as only secondary characters.

The fact that the new film aims to look at a young Cylcops (Tye Sheridan) means there could be potential for his brother, Havoc, to also be a part of the story. Though introduced briefly in X-Men: Days of Future Past and played by actor Lucas Till, he barely had any screen time.

Often overshadowed by Cyclops, Havoc has the ability to take in and redistribute plasma energy. He is incredibly loyal to his brother too and the family dynamic could develop a new angle for the movie.

Set in the 1980s, the new X-Men film will see the return of First Class and Days Of Future Past alum James MacAvoy as Charles Xavier, Michael Fassbender as Magneto, Evan Peters as Quicksilver, Rose Byrne as Moira MacTaggert and Jennifer Lawrence as Mystique.

The Marvel-inspired film will also introduce a new set of young actors for some of the franchise's most iconic roles. In January director Bryan Singer announced that HBO's Game of Thrones star Sophie Turner would be coming on board as Jean Grey, with Tye Sheridan (Mud) taking on the role of Cyclops and Alexandra Shipp (Aaliyah: The Princess Of R&B) playing Storm.

X-Men: Apocalypse is scheduled to hit theatres on May 27, 2016.
