Katsu Don makes another attempt at destroying the Legends World using Windblade as well as the mutant Autobot Targetmasters, who Windblade can manipulate through her bond with Pinpointer. The Wreckers arrive from the post-G2 era to aid in the world's defense only to be pinned down by the Targetmasters, and when Twin Twist breaks off to take on Windblade by himself, he gets decapitated. However, Twin Twist is aware of the Zodiac's existence in the Legends World and somehow calls it to his side, using its power to transform his severed head into a Headmaster and his body into a Z Mode "Drill Base" that in turn uses its drills to generate electromagnetic waves that sever Windblade's connection to Spoilsport. Twin Twist grabs the Targetmaster and, revealing that his special ability is to grant any weapon the properties of a drill, unleashes a "Spoil Drill Hurricane" attack against Windblade that frees Peacemaker from her control.
Chromedome is surprised that Twin Twist can freely control Zodiac energy, and Springer explains that he and Topspin are space pioneers known as the Powered Masters... as well as the true creators of the Legends World. The two Jumpstarters tell Katsu Don "long time no see" and invite him to test who's stronger—them, the creators of this world, or Windblade, its destroyer.
In the year 2004 of the G1 World, Topspin and Twin Twist hear about the Legends World from Whirl and Roadbuster, and as space pioneers and Powered Masters, think it would be nice to establish a paradise of a world someday. Decades later in the G2 era, they two are asked by Katsu Don for their cooperation in creating an experimental new universe also named "Legends", and realize he must be talking about the same world since time has no meaning when it comes to alternate dimensions. Concluding that they must create the Legends World or else Whirl and Roadbuster will never be born, they steal the Zodiac, inspired by Dai Atlas's using it to create a new planet in Planet Z's solar system, and use it in conjunction with Zamojin telepathic powers and the Space Pirates' proton energy to create the Legends World.
Katsu Don is outraged that the Jumpstarters have broken their promise not to interfere with their creation and sics Windblade on Topspin, but he easily avoids her thanks to having used the Zodiac to become a Headmaster—this combined with being a Powered Master and Targetmaster grants him the power of a Triplemaster—and calls upon the Zodiac to recreate everything Windblade and the Targetmasters have destroyed. Katsu Don himself enters the fray, insisting that the Legends World is dangerous because of its connection to the powers of the Zamojin and must be destroyed, but the Jumpstarters, determined to defend their creation, combine into a vehicle form known as Attack Powered and soundly defeat him and Windblade. With Windblade restored to normal once again and Katsu Don captured, Springer assumes all's well that ends well. However, the Jumpstarters, now having recovered all three mutant Targetmasters, tell him it's not over yet...
