Lilo & Stitch has been controversial since its announcement, though generally, both critics and audiences seem to sway towards the more positive side this time around. Regardless of people's thoughts on the film, it has done extremely well so far, and one of the movie's major teases sets up a potential future for the franchise.

While Lilo & Stitch's reviews are skewing more positively, that seems very likely.

Lilo & Stitch Shows Experiment 624 As One Of Jumba's Designs

Jumba Was Very Busy Before The Events Of Lilo & Stitch

During Lilo & Stitch's ending, Jumba, who is the remake's main antagonist, was looking through his numerous experimental creatures as he attempted to transform Stitch into Experiment 627. This is so that Jumba can make a pure evil version of him while removing his sense of empathy. While swiping through the catalog, one was called Experiment 624.

The character's design is very clear, with the pink hologram outline shining through, so even though it went by quickly, the reference was pretty hard to miss. While it could seem like just a fun Easter Egg, this moment actually references a fairly important character from the Lilo & Stitch franchise.

Experiment 624 Is Angel, A Major Lilo & Stitch Character

She Appeared Throughout Multiple Shows And Movies

Angel was a character who wasn't actually introduced in any of the Lilo & Stitch movies. She was introduced in Lilo & Stitch: The Series, which ran on ABC and Disney Channel from 2003 to 2006. Angel was a pink counterpart to Stitch, with the ability to sing a siren song that reversed someone's morality, meaning that she could be used to essentially make a good person or other experiment evil. She was smuggled to Earth by Jumba during his initial attempt to capture Stitch, but obviously, she didn't actually show up during the first movie.

When she appeared in Lilo & Stitch: The Series, Angel was reactivated by Gantu as he continued to fight against the group in the show after his defeat in the first movie. She was antagonistic for a little while, willingly working with Gantu to trap Stitch and make him evil again. However, eventually, she did turn good and became romantically involved with Stitch in later episodes. She reappeared in Leroy & Stitch as a minor character and had a recurring role in the Stitch! Anime that ran for a few years after.

How Lilo & Stitch's Angel Tease Sets Up A Sequel

She Could Be A Big Part Of The Next Lilo & Stitch Movie

As the new Lilo & Stitch referenced both Experiment 627 and 624, being evil Stitch and Angel, it is a big possibility that the next Lilo & Stitch movie will include both of these characters as major parts of the story. While they were only brought to the franchise in the television series, and not in the first sequel, which saw the introductions of Sparky and Reuben, they remained pretty big after their introductions until Disney stopped producing Lilo & Stitch media.

While Disney has not confirmed a sequel to the live-action Lilo & Stitch remake, the amount of money that the movie earned in its first weekend alone means that a continuation is almost guaranteed. The filmmakers will have a lot more creative freedom to do as they wish, making Angel's premature introduction much more likely. Lilo & Stitch showing off Angel like this was a great way to foreshadow another installment, one that could pay off very well in the future.
