The mini-series that acts as Akira Toriyama's final project concludes its run on United States airwaves tonight. The episode starts with Goku successfully transforming into Super Saiyan 4 as an adult. Goku begins fighting Gomah as a distraction so that Piccolo will be able to land 3 consecutive hits to the back of Gomah's head in order to remove the Evil 3rd Eye/Tertian Oculus from Gomah's forehead. Goku puts up an even better fight against Gomah as Gomah quickly loses his composure.
Unfortunately, the power of the Evil 3rd Eye/Tertian Oculus heals Gomah which allows him to keep up with Goku. Gomah also uses the power of the Evil 3rd Eye/Tertian Oculus to aid himself in other ways, such as creating a giant septor that launches multiple magic balls and trying to surround Goku by levitating rocks. As Goku & Gomah fly around at a fast pace, the fight briefly takes places within the underground section of Gomah's arena before they reemerge to the surface. Eventually, Goku powers up to a significant degree which catches Gomah off guard.
After the power up, Goku begins to charge a Kamehameha. Gomah uses the power of the Evil 3rd Eye/Tertian Oculus to create an magic shield to protect himself but the Kamehameha manages to break through the magic shield…and even manages to shoot through Gomah's torso. The Kamehameha is so powerful that it continues to shoot through the Demon Realm's 2nd World near Tamagami 2 and through the Demon Realm's 3rd World near Tamagami 3. This leads to the creation of a hole in the Demon Realm's 1st World that has a waterfall.
The hole in Gomah's torso provides Piccolo with an opportunity to strike…but Gomah manages to hit Piccolo before he can deliver a 3rd consecutive hit to the back of Gomah's head. The power of the Evil 3rd Eye/Tertian Oculus begins to heal Gomah's torso and creates a magic barrier to prevent Goku & the others from interfering with the healing process. After healing, Gomah powers up to toss Goku & the others around the arena while delivering an evil laugh. Kuu ends up being tossed near Gomah's head…and uses the Book of Magic Items to land 3 consecutive hits to the back of Gomah's head, thus removing the Evil 3rd Eye/Tertian Oculus from Gomah's forehead.
Without the Evil 3rd Eye/Tertian Oculus, Gomah returns to his Normal Form and Gomah's arena breaks into 3 parts. The Evil 3rd Eye/Tertian Oculus ends up landing near Glorio who wastes no time stepping on it in order to destroy it. Panzy compliments Glorio for destroying the Evil 3rd Eye/Tertian Oculus and they both compliment Kuu for removing the Evil 3rd Eye/Tertian Oculus from Gomah's forehead...after a moment of staring at him in disbelief and Kuu comments about the stares. Most of the other present characters join in on complimenting Kuu before complimenting Goku for putting up a great fight against Gomah as he flies down to join them (still in Super Saiyan 4 Form) and Goku is glad that "it all worked out".
Sometime later, Gomah is tied up and furious when Neva notes how short Gomah's term as the Supreme Demon King lasted (while also being confused by Neva not acting senile). Arinsu & Marba arrive with a bottle with the intent to trap Gomah in it (in a manner similar to the Evil Containment Wave) for 100 years; Piccolo notes that Gomah didn't actually mistreat Dende which Gomah capitalizes on to insist he has good qualities…which leads to Piccolo that they only seal Gomah in the bottle for 99 years. Using her own magic, Arinsu brings out Degesu (who is still tied up) and suggests sealing Degesu in the bottle alongside Gomah which Marba agrees is a "splendid idea". After sealing Gomah & Degesu into the bottle, Marba mentions that there's a garden and games within the bottle while Goku (who is back in his Normal Form and has picked up the Power Pole) hears Gomah shouting from within the bottle.
Arinsu asks who will take over the position of Supreme Demon King now that Gomah & Degesu has been sealed away and is surprised when Shin points out she wanted the position. Shin admits even he's surprised that he's considering her a qualified candidate but says she "held on to something resembling a conscious" which Arinsu finds "insulting" as she insists she hasn't abandoned her plans…although she is surprised when Neva asks if she still wants to make Demon Realm into a "terrifying" realm that will make the Mortal Realm fearful; Arinsu says she isn't willing to take the position without the Demon Realm's set of Dragonballs as she believes that's what would ensure her term wouldn't end in a single day due to being usurped…which leads to Neva revealing that the one who manages to defeat the Supreme Demon King in a fight is also the one who becomes "the first in line" to become the new Supreme Demon King. This leads to the other present characters realizing that the person who fits the description Neva gave is Kuu.
After letting the revelation sink in for a moment, Kuu gladly accepts the position and gains a white cape that resembles Dabura's cape. Kuu proceeds with declaring Arinsu his Vice Supreme Demon King while also declaring Duu, Glorio, Neva, Kadan & Marba his Ministers. Kuu even extends invitations to the Z-Fighters to join his cabinet but Goku politely declines as they plan to return home; when Kuu asks if anyone else wants to be a Minister, Hybis volunteers…but it goes unnoticed. Kuu then flies towards a crowd with a confused Arinsu as he describes his plan to make the Demon Realm "a good but still pretty frightening place to live"; Piccolo notes he has no objections to the era of Kuu as the Supreme Demon King.
At a later point in time, the group arrive at Kadan's Castle in the Demon Realm's 3rd World where Panzy provides Bulma with a generous supply of Majilite while the "Majin Brothers" provide Shin some giant cookies (with Shin politely admitting he doesn't need to eat but he still appreciates the gesture). During these interactions, Vegeta insists to Goku he could've defeated Gomah without Goku getting involved while Goku tries to convince Vegeta to not be hung up about how things went down. When Vegeta accuses Goku of keeping a secret transformation, Goku realizes Vegeta is referring to Super Saiyan 4 (and even outright uses the name) and explains that he had trained really hard after the fight with Kid Buu but admits he didn't know if he'd "be able to pull it off"; when Vegeta grumbles about Goku getting lucky "at the Super Saiyan Bargain Sale", Goku compliments Vegeta for unlocking Super Saiyan 3…which leads to Vegeta trying to pass it off as a new form called "Ultra Vegeta 1" but Goku just laughs off Vegeta's improvised name for the form. Neva asks Piccolo & Dende if they would be willing to stay in the Demon Realm and they both politely decline but Dende recalls some (Universe 7) Namekians becoming nomads after Frieza destroyed Planet Namek and offers to suggest the Demon Realm as a home for the Nomad Namekians which Neva appreciates.
Eventually, Panzy informs Goku that the airship is all loaded up with the necessary supplies and Kadan points out to Goku that the "shield of light" being removed from the Demon Realm Tunnel also removed the "heavy air" from the Demon Realm's 3rd World as a way to lead in to him thanking Goku for all he & his friends have done for the Demon Realm. As Glorio prepares the airship for takeoff, the two groups bid farewell to each other and Kuu mentions he'll call the Z-Fighters if anymore trouble comes to the Demon Realm with Goku graciously accepting should the need arise. Panzy joins Glorio on the airship to escort the Z-Fighters back to Universe 7. The end credits showcase the Z-Fighters back on Earth have been restored to their proper ages while also showcasing the Tamagami Trio as well as Gomah & Degesu inside the bottle.
After the end credits, Goku asks Glorio (but calls him "Gliro" which actually doesn't bother Glorio, this time around) if they can make a quick detour to the shop from the 4th episode because the Senzu Bean supply on Earth is running low and Goku figures stocking up on Medi-Bugs (Revive Buga, more specifically) would be a good substitute; Glorio is willing to oblige Goku's request and the group arrive at the shop. After a moment, the female shopkeeper recognizes Goku & Shin but is surprised by how they are adults now; she initially wonders if it might've been a side effect of the Medi-Bugs and Goku confirms that wasn't the case but does compliment the Medi-Bugs for being helpful. Bulma is disgusted when she finds out that Medi-Bugs are literally bugs…but quickly decides to buy the shop's entire stock of Beaut Bugs when the female shopkeeper mentions eating a Beaut Bug will make one's skin "10 years younger". While browsing around, Panzy stumbles upon a jar that contains…2 more copies of the Evil 3rd Eye/Tertian Oculus. The female shopkeeper casually mentions ordering 3 of them at some point in the past but only managed to sell one of them due to how expensive they are (along with many being unnerved by them too). The episode ends with Goku, Bulma, Shin, Glorio & Panzy continuing to look at the jar in shock as the female shopkeeper casually offers to give the group a discount if they buy the remaining 2 copies of the Evil 3rd Eye/Tertian Oculus.
As of tonight, DBD completes its Toonami run. I didn't expect Kuu to be the one to remove the Evil 3rd Eye/Tertian Oculus from Gomah's forehead and become the new Supreme Demon King but in hindsight, it's the kind of twist Akira Toriyama would pull off along with the reveal that the Evil 3rd Eye/Tertian Oculus was a store bought item with multiple copies. Considering how she was the catalyst for this saga by making Gomah paranoid, I feel Arinsu got off rather easy among the villains. It was cool to see more of SS4 Goku in action and while Goku's word choice to Vegeta confused some viewers, interviews with staff/crew members did confirm that Neva's magic was the catalyst for Goku unlocking Super Saiyan 4 (such as the one found
here) which suggests Goku was saying he believed a form beyond Super Saiyan 3 existed in theory and he was training to unlock it in practice. With Goku wanting to stock up on Medi-Bugs, hopefully there's a chance a future saga will feature a Medi-Bug Fusion in action. Likewise, here's hoping it won't be much longer before the next animated series in the franchise arrives.
