LEGO Star Wars: Rebuild the Galaxy: Pieces of the Past confirmed the Death Star's new name, and it has some room for improvement. The new LEGO Disney+ special that follows the story of a Force Builder named Sig Greebling (Gaten Matarazzo) who accidentally recreated reality using the Cornerstone, meaning that some heroes become villains while the usual foes turn into good guys. The reality-altering event didn't just change some of the iconic characters from the galaxy far, far away, but it also transformed the franchise's most dangerous killing weapon: the Death Star.
While the LEGO Special's Death Star role as a killing weapon in the overarching story remains the same, LEGO Star Wars: Rebuild the Galaxy: Pieces of the Past gave it an entirely different name while also serving as a backdrop to one of the Disney+ special's thrilling action sequences.
LEGO Star Wars: Rebuild the Galaxy: Pieces of the Past Episode 1 confirmed that the Death Star in this alternative universe is called Battle Ball, a giant superweapon built into a LEGO diorama shape.
The premiere pulled back the curtain on this new Death Star's origin, with Darth Rey confirming that the Battle Ball is a weapon designed by Darth Jyn Erso (a twisted version of Felicity Jones' protagonist from Rogue One) as "a way to bring the Alliance to its knees" after Darth Dev's death.
While the new title is clearly a part of LEGO's trademark humor, the series could have conjured up something a bit more clever than the 'Battle Ball.'
The Battle Ball's design is inspired by LEGO's UCS Death Star set, which consists of over 9,000 pieces and has 38 minifigures.
Darth Rey and Darth Jyn Erso are trying to convince Sig into choosing a planet to destroy by using the Battle Ball, but they are interrupted by the arrival of Sergo aboard the Dark Falcon, who attacked the space station.
Episode 1 also showcased an impressive chase sequence as the different Sith Lords try to chase down Sig and his allies inside the Battle Ball, featuring encounters between Darth Rey and Darth Bob, Darth Rose Tico and Sig, and the surprise inclusion of Landolorian and Grogu shifting alliances to join Sig and the heroes.
In the end, the Battle Ball was eventually destroyed by Sergo by paying homage to what Luke Skywalker did in Star Wars: A New Hope.
LEGO Star Wars: Rebuild the Galaxy: Pieces of the Past serves as the sequel series to LEGO Star Wars: Rebuild the Galaxy. The four-part series has a star-studded cast, headlined by Gaten Matarazzo, Ashley Eckstein, Ahmed Best, Kelly Marie Tran, Sam Witwer, James Arnold Taylor, and Cameron Monaghan (who plays Cal Kestis in his first Star Wars TV debut on Disney+).
LEGO Star Wars: Rebuild the Galaxy: Pieces of the Past premiered on Disney+ on September 19, 2025.
Why The Death Star's New Name Feels Like a Missed Opportunity
While the four-part mini-series is not canon and the superweapon's presence is minimal, the Death Star's new name in LEGO Star Wars: Rebuild the Galaxy: Pieces of the Past stands out. The Battle Ball fits the LEGO special's lighthearted and kid-friendly approach, but feels like untapped potential.
Rather than using a few synonyms to come up with a slightly distinct name for the Death Star, the show could have subverted audience expectations by making this universe's version of the battle station more friendly and welcoming.
Darth Fisto's revelation that the Battle Ball’s secondary missiles are malfunctioning slightly diminishes the superweapon’s threat, playfully reinforcing its resemblance to a child’s unfinished LEGO creation. Perhaps the name could have reflected the faulty nature of the superweapon's capabilities in order to double down on the over-the-top LEGO humor.
Alternatively, Pieces of the Past could have poked fun at the name of the Death Star itself. In-universe, the Death Star is a rather unambiguous name that tells the galaxy exactly what it is. Although the Empire can be cartoonishly evil at times, the use of this name is still a little obvious, leading to material that would have been ripe for a few playful digs at the absurdity of such a title.
While the Battle Ball is a bit of a miss, LEGO Star Wars: Rebuild the Galaxy: Pieces of the Past gets a lot right with its astute observations of the galaxy far, far away (check out our review on why the show is so much fun).
