Despite being able to save his dog, Buu loses control after Mr. Satan is shot by the same gunman. Buu separates into Good Buu and Evil Buu. Evil Buu eats Good Buu after a reflected chocolate beam and the powerful Super Buu emerges. Now able to detect ki, Buu makes a B-line for Kami’s Lookout.
Goku had asked Buu for two days for Goten and Trunks to be able to prepare, which he granted. He shows up a day early while Goten and Trunks sleep off their first successful fusion dance. Knowing that they can be wished back, Piccolo encourages Buu to kill some more people. Taking his words literally, Buu kills everyone on earth with one attack. He then demands to see this strong fighter, which Piccolo says will be ready in one hour. He quietly tells Krillin to wake the boys up and get them in the Hyperbolic Time Chamber. He leads Buu there after only half an hour, but purposely takes the long way to give the boys more time.
Once inside, Piccolo destroys the one exit out of the Hyperbolic Time Chamber after Gotenks pretends that he’s used up all of his attacks. Buu screams himself a portal back to Kami’s Lookout and leaves Piccolo and Gotenks behind. Gotenks reveals that he can go SSJ3 and soon makes his own portal. By the time he and Piccolo return, Buu has already eaten everyone. With Kami’s Lookout completely destroyed, Gotenks returns to base form and defuses right when he’s going in for the kill on Buu. Meanwhile, Piccolo does nothing but make funny faces and shout at rubble. With his training finally completed, Gohan returns and is actually stronger than Buu. Piccolo and the others find Dende who praise the fact that Mr. Popo threw a weak Namekian off of Kami’s Lookout to save the Dragon Balls. Buu self destructs, but not before Gohan saves everyone. After regenerating, Buu absorbs Piccolo and a newly fused Gotenks. He makes Gohan eat dirt.
Goku is given Old Kai’s life force to help in the fight against Buu and receives the Potara earrings, which also fuses two individuals into one powerful being but the fusion is revealed to be permanent. As Goku returns and is about to fuse with Gohan, Gotenks fusion wears off and Buu becomes weak. Thinking he no longer needs the earrings, Buu absorbs Gohan and Goku is no match for him. Sensing Vegeta has returned from the afterlife, Goku pleads the fusion case to Vegeta and after some convincing the two become Vegito.
Vegito seems to have the fight in the bag, but continues to toy with Buu because it’s not like the fate of the entire universe is in his hands or anything. Buu eventually absorbs Vegito, but he isn’t digested like the others thanks to the Energy Barrier he surrounds himself with. Once inside Buu, Vegito defuses and Goku and Vegeta rescue Piccolo, Gohan, Goten, and Trunks after Vegeta nearly barfs on some worms. To their surprise, they also find the fat version of Buu. Once releasing him, Buu undergoes another transformation resulting in his original, incredibly powerful, and most insane state Kid Buu.
When Buu first gets to Kami’s Lookout, he yells “Produce!” over and over again. Working in retail at a grocery store may have tainted this part of the anime, but honestly the first thing that came to mind was Buu having the overwhelming desire for fruits and vegetables. This is kind of a big coincidence because Buu is seen eating fruit in Mr. Satan’s room after the ten year time jump in the next saga. It’s then explained that Buu wants Piccolo and the others to produce the strong fighter Goku spoke of the last time they met. Still it’s disappointing that Mr. Popo didn’t come out dressed in a giant banana costume or something.
Chi Chi is the first to die at the hands of Super Buu and it’s quite possibly the happiest and most stress-relieving event of the series. As if Chi Chi wanting to fight Buu with a wet mop wasn’t enough, she stomps over to him, slaps him, and then lectures him about “killing” Gohan. Buu sits there staring at the giant hourglass with green sand that Piccolo created and doesn’t speak for a long while. He finally says, “Do you like eggs?” before turning Chi Chi into an egg and stomping on it. You’re not only going to kill off the most annoying character of the show, but it’s also going to be the most random thing ever? This is the point where Akira Toriyama became legendary.
The fat version of Buu is a personal favorite, but Super Buu is pretty awesome as well. The entire Hyperbolic Time Chamber sequence with him, Gotenks, and Piccolo is pretty fantastic. The facial expressions are just insanely entertaining this saga anyway. Buu’s reaction when Piccolo destroys the only exit is hilarious as he only cares about chocolate, ice cream, and candy. Gotenks is pretty random as well. His attacks range from being really childish to really innovative (Super Ghost Kamikaze Attack). The awkward part comes after Buu eats everyone on Kami’s Lookout. Before everyone realized that Dende was still alive, they were still talking about using the Dragon Balls to wish people back. If Dende had been eaten, that wouldn’t have been an option.
Back in the Majin Buu Saga while SSJ3 Goku was fighting Majin Buu, Goku compliments Buu and tells him that he is the most powerful fighter he has ever faced. Buu then leans back, his nose grows, and he says “Thank you.” Gotenks pulls the same maneuver here after Piccolo yells something at him. Is it supposed to be a throwback to Pinnochio? Are Buu and Gotenks lying? It’s funny, but at the same time it doesn’t make a whole lot of sense.
As Goten and Trunks defuse and Gohan was still on his way back to earth, Buu crouches down and falls asleep standing up. Instead of running away to buy them some time, Goten and Trunks decide to make sure he’s asleep for who knows what reason (to write on his face with permanent marker obviously). Like the snot bubble coming out of his nose wasn’t a dead giveaway. Once Gohan arrives and Buu self destructs, Gohan saves Piccolo, Goten, and Trunks. When they’re flying later, Goten and Trunks are flying behind Piccolo and Gohan. Goten and Trunks have an entire conversation about Piccolo’s B.O. and it’s rather amusing.
Buu is a relatively awesome villain anyway, but he’s much more random before he starts absorbing people. If he has a nose, then he’s a little bit less awesome. Kid Buu gets things back on track as he’s pure evil and downright insane (chest pounding, sexy taunts, and destroying planet after planet along with himself every few minutes just because he can’t find Goku and Vegeta).
Once they die, Yamcha and Krillin go to Grand Kai’s planet and get a little bit of training from King Kai. Yamcha who explains he hasn’t trained in all of the years since the Cell Games suddenly starts fighting and training again. He beats Olibu with little effort. Olibu barely lost to Pikkon back in the Great Saiyaman Saga and now he’s losing to the guy who dies almost as often as Krillin does. What in the blue hell is going on here?
Once Buu absorbs Gotenks, he uses the Super Ghost Kamikaze Attack. The only difference is Buu’s ghosts are capable of using Kamehamehas and Vegeta’s Galick Gun. After using the Galick Gun, Vegito refers to them using Masenko (Piccolo’s attack that Gohan also uses). It only makes things more confusing.
Dragon Ball Z aired in Japan nearly 20 years ago (the Kid Buu Saga ended in 1996) and yet no word has ever been mentioned (on this end anyway) about Vegito being turned into a coffee jawbreaker and fighting Buu. Not only that, but Buu loses to a piece of candy. Are coffee jawbreakers even an actual thing? Does anyone else think this is massively ridiculous?
The Funimation dub really pusses out with the vulgarity after the Frieza Saga. You soon realize that every time somebody says, “Oh darn!” or “Blast!” that you’re missing out on some quality cuss words. It wouldn’t really be a big deal if their orange brick boxed sets weren’t advertised as being uncut. It doesn’t really become too bothersome until Vegito is swallowed by Buu and defuses back into Goku and Vegeta. Phrases “Great galaxy!” and “Son of a Namek!” are used in place of anything remotely sensible and instead of just saying “butthole,” “crap,” “poop shoot,” or even “poo,” they refer to Buu taking a crap as his “southern exit.” If it wasn’t for the extremely well-animated facial expressions of Goku and Vegeta in certain episodes and the entire “people popcorn” exchange once they escape from Buu’s body, the entire sequence would be a waste of time.
