Trama

As Goku and his companions head to where Gomah is, engine trouble causes them to land on a certain planet. The place they land happens to be a surprise-filled planet where even Supreme Demon Kings are afraid to tread.

With Goku and his companions having now also obtained the Two-Star Demon Realm Dragon Ball, a panicked Gomah orders Degesu to disable the Sir Warp so that they are unable to travel to the First Demon World to which he begrudgingly does so. Meanwhile in the Second Demon World, the Demon Realm Plane carrying both parties suffers engine trouble and crash lands to a planet below though everyone escapes unharmed. While Bulma and Panzy work on repairing the plane the rest of the group take a look outside. Vegeta suggests that the fighters amongst them simply fly on ahead to the First Demon World, but Shin tells him that is impossible for a mortal being to pass through the Sir Warp. Just then Neva realizes where it is they've ended up, the planet Mega. Home to the Megath, Mega is known as being the second most dangerous planet in all of Demon Realm, a planet where everything is gigantic in size and even the Supreme Demon King dare not enter. Elsewhere, Glorio contacts Dr. Arinsu in private to let her know that they've obtained the second Dragon Ball. Between the two that Glorio has obtained and the one that Majin Duu was able to recently obtain, Dr. Arinsu now has the complete set. As Goku heads off to explore he finds a giant apple to feast on, when suddenly he is attacked by a horde of giant hamsters, each roughly twice the size of Goku. The pack attacks while Goku, Vegeta, Piccolo and Glorio try to fend them off but are surprisingly resilient. However, when footsteps begin to shake the earth underneath, the nervous hamsters run off back into the long grass. Suspicious of the source of the footsteps, they find that they belong to a Megath child, a behemoth of a being reaching hundreds of feet high up from the ground. On its way home from school the child sits down and begins to snack on one of the tentacles that belong to the Kraken. The child is soon joined by a dog that quickly sniffs them out and begins searching for the group. Bulma and Panzy head off to finish repairs on the plane while Goku does his best to slip away from the giant dog. It finds him however and the fighters are tasked with trying to keep it away from the plane, so it doesn't get destroyed. When Goku accidentally flies into the dog, he is approached by several giant ticks. After also fighting them off, the dog then spots the glint of the planes Majilite and excitedly runs towards it, barging past everyone and almost pouncing on it if not for Goku's Kamehameha blasting the dog away. The girls finish the planes repairs and plan to take off, but the ongoing commotion causes the child to take notice and head over. The child spots the plane in the air and attempts to swat it, but Goku intercepts him. The plane is saved but Goku is overpowered and falls into the child's school bag. The child removes a ruler and again tries to strike the plane, but Goku emerges from the bag as a Super Saiyan and halts him with his Power Pole. Again, Goku saves the plane but is overpowered, narrowly dodging a heavy foot stomp that follows. Goku and the others then board the plane and leave the planet. When Neva tells them that adult Megaths are even more terrifying, Goku asks why they don't become the Supreme Demon Kings instead, but Shin explains that Megaths are generally a laid-back race not interested in such things. Out of curiosity Vegeta asks what the number one most dangerous place is in the Demon Realm. The answer: Giga, where even large beings known as the Gigath live. The group sit back and relax while they have the chance as they continue their journey.
