While Enchantress is not the most well-known antihero of DC comics, she has already received two separate live-action versions -- one in the Arrowverse's Legends of Tomorrow and the other in the DCEU's Suicide Squad. And they could not be more different.
Let’s start with a bit of background: Enchantress in an evil magical entity who can take over a body of her host, June Moone, and use it for her own purposes. June was put in this position after she inadvertently welcomed the possessing spirit into her body. With the trigger word "Enchantress," June transforms in appearance and allows the dark magician to take control. The poor girl tries to make the most out of the situation, joining several groups (most notably Justice League Dark and the Suicide Squad) in an attempt to utilize her newfound power for good. It doesn't always go in her favor, but hey, it's the thought that counts.
The Suicide Squad film introduces the eponymous team of doomed villains, with Cara Delevingne as the Enchantress; however, she isn’t a member of the team. In fact, she is portrayed as the antagonist. And while that fits the overall nature of the sorceress, it betrayed her roots as a member of the Squad. Furthermore, June Moone was perhaps the unluckiest archaeologist in history when she got possessed by the evil entity for seemingly no reason.
This somewhat contradicts the beginnings of June and Enchantress’s struggle. In the comics, June accepted the power in order to do good and save innocent people. Enchantress herself became an unhinged somewhere down the line -- there wasn’t an instant need to destroy the world.
In the comics, Enchantress is one of the most powerful beings in the universe. It was shown she can even survive being separated from her host, though she began slowly losing her mind eventually as a result. The movie, however, limited her power to a ridiculous degree. Throughout, her power was being contained and controlled by those who possessed her heart. Poetic, but not very fitting when one considers the implications.
The movie took what made the Enchantress so fascinating and toned it down, making her no more than a run-of-a-mill ghostly apparition who can possess people for a while, and can be exorcised with enough willpower. That isn't to say they failed completely, as the plot point about a brother with similar power is a direct echo of the old comic storyline.
During the many adventures June had with Enchantress in the comics, the two didn’t always see eye to eye. However, there were incidents fairly early in their history when June even sought Enchantress out because she felt lost without her power. Suicide Squad eliminated the underlying potential of her as a reluctant hero. Enchantress was originally placed in June’s body with a hope that an evil entity can be used for good. That is the main struggle June faces, and also the motivation for her to join the various teams, Suicide Squad being the main one. June is a good person, Enchantress is evil by nature, and their duality makes for some fascinating encounters.
It’s safe to say that Suicide Squad’s Enchantress didn’t live up to the hype. Audiences didn’t see much of her magic, and her motivation was revenge on all of humanity.
Legend of Tomorrow, on the other hand, offers a different look at the infamous entity. While not much is known about her or her motivations beyond the few important plot points, Enchantress in the TV series holds a lot of untapped potential. From her role as a keeper of one of the pieces of the Loom of Fate, she’s established as one of the most powerful within a universe -- a direct homage to her abilities in the comics. Not only that, but her presence in ancient Egypt also stresses her age and the fact that there have been other hosts before June.
Enchantress seems to be forced to maintain a status quo, prevented from meddling with mortals (or so the rule goes). However, the sorceress still manages to show off some of her power in small but significant ways. The show’s use of casual magic goes a long way to establish her as someone with a supernatural background.
Additionally, so far there are no strings attached that could stop Enchantress from displaying her full power (unlike the heart in the movie). This version of the character is freer in both her actions and interactions. She has a timid friendship with Clotho, and destruction isn’t her main goal. In fact, Legends of Tomorrow may have drawn inspiration from the early incarnations of the comic Enchantress, where her evil rampage began only when Supergirl’s interference cost her the fulfillment of an important goal. It is likely the show took the liberty to portray the entity before she snapped, since the comics have several instances where Enchantress’s evil nature is counterweighted by her host’s good intentions.
These two versions of Enchantress remain at odds mainly due to this power struggle. Suicide Squad’s story had to be more contained, and so Enchantress couldn’t do things as she pleased. Legends of Tomorrow seems to pay homage to her roots, keeping her as a powerful being who can transcend time and whose power we don’t truly know.
