It’s time once again for some 31st century frivolity, so let’s board our time bubble and head to the future for another adventure with the Legion of Super-Heroes! Nope, we’re not reviewing an LSH comic this time, but rather a new LSH animation film that was released on February 7th. The plot is rather complex, so rather than wrack my aged brain, I borrowed a 1700-word review from fugitives.com and pared it down to 950-words along with some major wordsmithing.
Legion of Super-Heroes
Directed by Jeff Wamester and featuring Meg Donnelly and Harry Shum Jr.
Warner Bros./DC, 2023, 1h 23m.

Plot
As Kara Zor-El enjoys some rare leisure time with her mother, General Alura Zor-El, the High Defender of Krypton, the planet’s red sun suddenly begins emanating destructive flares. As the planet’s core starts crumbling, Alura manages to secure a single interstellar pod to save her daughter. A distraught Kara watches helplessly as her mother spends her final moments assuring her daughter of her love and asking her to watch over her baby cousin, Kal-El, the future Superman, who is also being transported to safety. As Kara’s space pod rockets away, debris from Krypton’s destruction knocks it off course, and the craft drifts into the vast cosmos.
Due to her pod’s wayward journey, Kara arrives on Earth much later than Kal-El. Unlike her cousin, who has since learned to master his super powers, Kara, now known as Supergirl, struggles to control hers. During a scuffle with the villainous Solomon Grundy, Kara causes significant property damage due to her recklessness. Batman shares his skepticism about her with Superman, which Kara overhears. Superman sets out to console her, while Batman spots the futuristic weapon previously wielded by Grundy and senses suspicious activity, as someone with Grundy’s intellect wouldn’t be able to acquire something so advanced.
Superman tries his best to comfort Kara and takes her on a journey to the 31st century to the academy of the Legion of Super-Heroes where he advises she can receive valuable training. The Legion is a team of young crime fighters with unusual powers who banded together after being inspired by the past heroics of Superman. While Superman encourages Kara to join the academy, a team of mysterious assassins attacks Star Labs in the 21st century. Batman subdues them, but they consume suicide pills before he is able to interrogate them. However, their involvement with the previous attack is confirmed by their weapons, which match Grundy’s. A severed head of the supervillain Brainiac can be seen in the labs.
At the Legion academy, Kara befriends several aspiring cadets, including Bouncing Boy, Dawnstar, Invisible Kid, Mon-El, Phantom Girl, Triplicate Girl, and (no foolin’) Arms-Fall-Off Boy. Kara mistakes another trainee, Brainiac 5, a twelfth-level-intellect descendent of the original Brainiac, to likewise be a threat and immediately confronts him. Later, upon learning that B5 is trying to redeem his infamous heritage, Kara starts acting sympathetically towards him.
Three Legionnaires, Timber Wolf, Shadow Lass, and Chemical King, safeguard the Legion complex, as the rest of the bloated roster are missing in action. Timber Wolf expresses his distrust of B5, as all the past clones of Brainiac have turned out to be villainous.
A group of assassins attempts to infiltrate Legion HQ and murders Triplicate Girl. Despite his plea of innocence, the three Legionnaires suspect B5 is the culprit after discovering he orchestrated his admission to the academy and remand him to a security cell.
After learning the assassins belong to the “Dark Circle,” a space terrorist cult of unknown origin, Kara visits the confined B5 and inquires about a course of action. He confesses he joined the Legion academy to stop an attack by his villainous Brainiac clone family, who were associated with Dark Circle, and were planning a heist of the Legion vault where an ancient reality-bending mechanism called the “miracle machine” is stored. B5 admits he used subterfuge because he surmised the Legionnaires would not have believed him due to his familial stigma. Kara frees him, and the duo sets out to secure the miracle machine before it falls into the wrong hands. Mon-El spots them and offers to assist in their effort.
The trio manages to override the Legion vault security due to B5’s twelfth-level intellect. However, Mon-El betrays them and stabs Kara with a Kryptonite dagger. He reveals himself to be a race supremacist linked to the Dark Circle. Meanwhile, the Legionnaires are ambushed by hordes of Dark Circle assassins and, after being defeated, are held captive along with the trainees. The leader of the Dark Circle emerges as supervillain, Brainiac. After his death in the 21st century, he created the Dark Circle to sustain himself by preserving his consciousness and incorporating several clones into his body—thereby creating a monstrous composite version of himself. Brainiac confesses that he used B5’s intelligence to unlock the impregnable security of the Legion vault and that he will use the miracle machine to change reality according to his will.
B5 escapes with the injured Supergirl and uses his advanced technology to restore her health. The duo regroups with the trainees who escaped the Dark Circle’s clutches, and it is revealed that Triplicate Girl’s other two selves survived. They manage to rescue the other trainees, and Dawnstar sends an SOS signal to the missing Legionnaires. The team launches a retaliation against the Dark Circle as B5 and Supergirl confront Brainiac. However, Brainiac successfully links himself to the machine and starts changing the universe according to his will. B5 manages to foment discord among the integrated Brainiac clones and as they fight for supremacy, the clones tear their host body apart, thereby killing themselves and Brainiac. In her effort to undo the effects of the machine, Kara accidentally enters its alternate reality where she encounters her mother. For a brief moment, Kara contemplates bringing Alura and Krypton back, but B5 convinces her that the priority is to save the universe. Kara wills the miracle machine out of their reality—thereby saving the universe. After a brief scuffle, Mon-El is taken into custody, and the missing Legionnaires return to HQ. Because of their demonstrated bravery, all of the trainees are inducted into the Legion’s ranks. Kara communicates with Superman through a time portal and relates her enthusiasm for her new Legion role and for her new boyfriend, Brainiac 5.
Comments
Despite the title, this is actually a Supergirl flick with the LSH as the supporting cast. The plot was loosely based upon the Silver Age LSH tale, “No Escape from the Circle of Death!,” Adventure Comics #367 (April, 1968). Yes, I actually bought and read that comic when it first came out 55-years ago. Writer, Josie Campbell radically messes with LSH lore by presenting veteran members as cadets and Mon-El as a villain. Yes, Arms-Fall-Off Boy actually tried out for the Legion as somewhat of a lark in Secret Origins Vol 2 #46 (December, 1989). The Legion’s founders, Cosmic Boy, Lightning Lad, and Saturn Girl have cameo roles. Other Legionnaires spotted very briefly include Blok, Comet Queen, Element Lad, Ferro Lad, Gates, Gold Lantern, Karate Kid, Polar Boy, Power Boy, Sensor Girl, and Star Boy. Overall, this is a good, low-budget animation flick with an interesting storyline that holds the viewer’s attention. Although the LSH currently doesn’t have a book, it’s good to see DC carry on the franchise’s 65-year-old legacy.
