総力戦!究極の4体合体VS第7宇宙総攻撃!!
Sōryoku-sen! Kyūkyoku no Yontai Gattai Bāsasu Dai-Nana Uchū Sō Kōgeki!!
All-Out War! The Ultimate 4-Way Combo vs Universe 7's Total Offensive!!
Summary:
Vowing to defeat the U7 team even at the cost of his own life, Paparoni unleashes U3’s final tactic and merges with Kochiarator to become the gigantic Anilaza. The Omni-Kings are impressed with the size of this four-way fusion, while the U3 God of Destruction Mosco (still speaking through his angel interpreter) is confident they can now win. Anilaza fires blasts off at every remaining warrior in the arena, forcing 17, 18, and Freeza to dodge, while Jiren simply counters with a blast of his own.
Super Saiyan Vegeta tests Anilaza out with a Big Bang Attack, but Anilaza easily swats it aside and charges at the U7 team, making it clear that his power and speed have both greatly increased. After managing to evade Anilaza’s assault, 17 and 18 join up with Goku, Gohan, and Vegeta, while Goku declares that their only option is to attack Anilaza together. Following Gohan’s advice, the group moves quickly to confuse their giant opponent (with Goku powering up into Super Saiyan God), and each go after a different limb. However, Anilaza not only manages to track all five of them, but proves fast enough to knock them each away before they can attack.
Goku wonders if Anilaza is quickly tracking their ki, but 17 points out that he and 18 don’t have ki like the others. Instead, 17 speculates that Anilaza is emitting sonar from his tentacle-like ears to instantly locate them. Anilaza next begins using his immense power to warp space, punching his fist through wormholes to directly attack distant opponents (much as Janenba did in DBZ Movie 12). One of these warp punches sends Goku flying, but Freeza kicks him back into the arena before he can fall out of bounds (“my leg moved on its own”).
Goku thanks Freeza for saving him, and asks for his help against Anilaza, who soon launches another attack against the entire U7 team. This time Anilaza starts grabbing at warriors, eventually getting hold of 18, who he tries to swallow (apparently because the U7 team members can simply rescue each other when one is about to fall out of bounds). Thankfully though Goku manages to save 18 at the last moment, and Anilaza begins firing off a barrage of homing blasts. 17 blocks these with one of his energy shields, but the continued assault manages to push him off the edge of the arena.
As 17 falls, 18 jumps down and kicks him back up into the arena, effectively sacrificing herself in his place. The Great Priest announces 18’s elimination, and as she materializes in the bleachers she tells 17 not to lose. For his next trick, Anilaza grows wings and begins to fly, then forms an enormous energy ball to take out the U7 team together with the arena. The five remaining U7 members power up to counter this attack, with Goku and Vegeta going Super Saiyan Blue and Freeza charging up into his Golden form.
All five fire blasts to hold off Anilaza’s energy ball, but are gradually pushed back. Changing tactics, 17 surrounds himself in an energy shield and jumps straight through the energy ball to attack the crystal sphere in Anilaza’s forehead. Though 17 is knocked back by Anilaza’s energy, he has achieved his goal: the crystal sphere (actually Anilaza’s energy reactor) shatters, throwing him off-balance enough for Goku and co.’s blasts to overtake him with one final push.
Defeated, Anilaza breaks up into his four component warriors (Paparoni, Koitsukai, Panchia, and Bollarator), who materialize in the bleachers. Though Paparoni apologizes for their loss, the U3 Kaioshin Ea says he did a great job. The Great Priest formally announces the total defeat of the U3 team, and the Omni-Kings charge up their blast to destroy the defeated universe. As the U3 gods and warriors start to vanish, a red devil-like creature named Mule pops out of a hatch in Mosco’s mechanical stomach, and thanks the U3 angel for all his support.
With U3 destroyed, Goku thanks 17, who explains that it was his instincts as an android that led him to guess the location of Anilaza’s energy reactor. Goku also thanks Freeza for lending a hand, and Freeza insists Goku still owes him one. The group is interrupted by their sole remaining opponents, the U11 team, and Jiren assures them that this victory against U3 will be their last.
9 minutes remain in the Tournament of Power.
