Magetta's History
Universe 6 Saga
Magetta is a member of the Metalman race from Universe 6. He is chosen by Vados to be one of the five fighters facing off against Team Universe 7 in the Tournament of Destroyers. He attends the competition on the Nameless Planet along with his teammates: Hit, Cabba, Frost, and Botamo. Magetta manages to pass the written exam to participate in the tournament, although he struggles with answering the questions as proven by the pipe on his head being set off. In the end, he barely passes with a 50% mark. He watches the first match between Botamo and Goku. Botamo loses to Goku because throws him out of the ring. Universe 6's next fighter is Frost who takes on Goku. After Frost defeats Goku and Piccolo by cheating and then loses to Vegeta, Magetta takes on the Saiyan in the next match. A new rule by Champa and Vados is made after Vegeta beats Frost, which is that if someone touches the barrier around the ring, it counts as a ring out.
After drinking a cup of lava, he goes in for a series of punches once the match starts, but Vegeta dodges them all without much effort and he tries kicking him on the head, but the result leaves his head buried within his body and creates an irritating shock wave. Magetta pulls it back out after violently striking himself and he is completely fine. Even after increasing his power, Magetta still couldn't land a punch on Vegeta due to his speed. Magetta then goes in for a tornado attack, when Vegeta dodges upward at the last minute. He is now in the best position against Magetta because he can't do any mid-air combat. Vegeta then fires multiple ki blasts at Magetta, who endures it and counters them with his Lava Spit, which is considered a qualification which gets stronger by the minute. Vegeta manages to avoid the full damage at the last second but is now at the risk of touching the barrier and getting disqualified. Fortunately for Vegeta, he transforms into his Super Saiyan form to brush off the damage from the magma attack, but Magetta starts to power up even further and increase the temperature of the barrier-encased arena, causing Vegeta to pant and sweat.
Magetta continues spitting lava again at Vegeta. He then lets out a hot water vapor attack which pushed Vegeta to almost fly out of the barrier. While Vegeta prepares for a Galick Gun attack, Magetta raises the temperature which causes the whole arena to become extremely hot. Magetta easily blocks Vegeta's Galick Gun with his Lava Spit which becomes solidified. He spits another lava on Vegeta and uses the lava to ambush Vegeta. He successfully hits Vegeta with a club created by the cooling the magma, making him fall out of the ring. However, Vegeta is lucky enough to land on one of the broken rocks from the stage platform. Magetta gets pushed back by Vegeta's ki after releasing it to break the barrier. Vegeta uses his Final Flash on Magetta, while Magetta prepares for another Lava Spit. However, Vegeta's Final Flash easily overcomes Magetta's lava and pushes him to the edge of the arena platform. As a result of Vegeta's Final Flash, Magetta becomes dizzy and is left open to Vegeta's attack. Despite trying to block it, Vegeta shouts out an insult which makes Magetta lose his will to fight, thus, Magetta falls out of bounds and Vegeta is declared the winner of the match. He is later seen crying because of Vegeta's insult while Botamo tries to comfort him. In the manga, Magetta is instead defeated when Vegeta destroys most of the ring and then fires a ki blast at Magetta to try and knock him out - insulting him while doing so - causing Magetta to easily fall of the ring from one blast to the surprise of Vegeta.
When Hit "lost" to Monaka and returned to the Universe 6 Team Champa was furious with the entire team as they had failed him. Magetta was afraid of the God of Destruction's wrath as Cabba attempted to calm him down. However, this was short-lived as the Omni-King and his guards appeared frightening Champa into forgetting what he was doing.
"Future" Trunks Saga
He is recruited by Champa for his baseball team. Gohan tries to take advantage of his inability to fly, but he teams up with Botamo to make up for this. In the end, Universe 6 loses and Champa makes them train for a rematch.
Universe Survival Saga
He, along with the rest of Team Universe 6, is seen waiting for the tournament to begin. Once the tournament starts, he momentarily fights Top, seemingly able to fight him on equal footing despite the massive difference in power between them. Magetta showed up later to save Botamo from being thrown off the arena by Vegeta. He then tried to defeat the metal man with insults, but the latter overcame his mental weakness and teamed up with Botamo to form a seemingly unstoppable duo, Bota Magetta, which gave Vegeta a hard time in a fight, but then the two of them were separated when Kale transformed into her Legendary Super Saiyan form and unleashed a powerful widespread ki attack. After Kale's rampage, Magetta fought Rabanra. Magetta looked at Roshi when he said Choo-Po, the same thing Magetta always says.
Auta Magetta then reappeared as Vegeta confronted Frost and fought the Saiyan in his Super Saiyan form with lava and rocks jammed in his ears. After trading punches with a while, Vegeta launched a Big Bang Attack at him, only for the robot to deflect the attack with his claw. He also took some ki blasts from Vegeta and saved Frost in the process. Master Roshi then tried to contain Magetta with his Evil Containment Wave, only for Frost to intercept and use his latest Evil Containment Wave Reflection and directed it towards Vegeta. When the Saiyan broke free thanks to Roshi, Vegeta blasted away Magetta's ear coverings and called him a "scrap metal bastard", making the robot lose his will to fight once more and left him wide open for Vegeta to kick him out of the arena, eliminating him from the tournament. After that, Magetta watched the tournament in silence, but during Pirina and Saonel's fight against Gohan and Piccolo, Champa jumped on his shoulders and told him to cheer them up too. The remaining warriors of the team were finally defeated and as a result, Magetta and all the others were erased with their universe.
In the manga, Magetta battles Piccolo, Gohan, Master Roshi, Tien Shinhan, and Krillin by throwing several punches at them. While Krillin is distracted by the battle, Frost charges at Krillin and knocks him off the arena. He also uses Magetta's fight to knock off Tien. Magetta is later seen being shot off the arena by Legendary Super Saiyan Kale when she loses control of her power.
Magetta is later revived with his universe when Android 17 uses the Super Dragon Balls to resurrect all of the universes that were erased.
