Dragon Ball is about a group of fighters that searches for the seven spheres that the series is named after. With these Dragon Balls, they can make any of their wishes come true. Eren is the main character of another popular manga, Attack on Titan.
He has always been determined to get what he wants and does anything he needs to in order to make that happen, though his wishes have changed a lot over the years. If he had the Dragon Balls, things would be much easier for him.
10 He Would Have Wished To Join The Survey Corps Early On
When the series first began, Eren had already wanted to be a soldier in the Survey Corps. Despite how the people around him felt, he admired characters like Levi and Erwin, hoping to be just like them one day.
However, he and Armin were the only two people in Shiganshina that actually wanted to go outside of the walls, so if Eren had the Dragon Balls when he was a kid, he'd probably use his wish on this.
9 He Would Wish That The Warriors Never Went To Paradis
The reason why so many people didn't support the Survey Corps was because they got comfortable in Paradis and didn't think anything good could come from going outside and fighting the Titans. Their opinions, however, changed once the Colossal and Armored Titans broke into their home.
Many people died, including Eren's mother, and the survivors had to go inside of Wall Rose, which became overpopulated and there wasn't enough food to go around. This was the worst condition that the people in the walls were in for 100 years and this only made Eren more determined to kill Titans.
8 He Would Wish For His Mother To Come Back To Life
Another way for Carla to be saved would be for Eren to wish that she would come back to life. He was very rebellious in the beginning of the series and never listened to her. He regretted this upon seeing that she could not move after part of the wall fell onto their house, with her trapped under the debris.
This was the last time Eren ever spoke to his mother as he saw her get eaten moments later. If he could resurrect Carla, he'd get a second chance and would try to be a better son.
7 He Would Wish To Have No Regrets
After Eren became a member of Levi Squad, he and his new comrades went on a mission with the rest of the Survey Corps, in which the Female Titan tried to capture him. He wanted to fight back but the other soldiers convinced him not to.
Levi told him that he didn't know what the right choice was and that he makes decisions based on what he thinks he'll regret the least. Upon hearing this, Eren trusted the squad and didn't fight. Unfortunately, his trust resulted in everyone except for him and Levi dying, causing him to regret his choice.
6 He Would Wish That His Comrades Weren't Traitors
When Annie turned out to be the Female Titan, Eren was shocked and didn't want to fight her. He trained alongside her and couldn't believe that she was a Titan. But this was nothing compared to learning that Bertholdt, a close friend of his, and Reiner, who he looked up to like an older brother, were the Colossal and Armored Titans.
When he first heard that this was a possibility, he didn't want to believe it, but he knew he had to fight them once he transformed. If it were up to him, his friends never would have attacked Paradis.
5 He Would Wish That Grisha Didn't Kill The Reiss Family
When Eren first learned that his father killed Frieda Reiss, as well as most of her closest relatives, in order to obtain the Founding Titan before passing it down to him, he was shocked and didn't feel like he deserved his powers anymore. In what could be considered his greatest moment of weakness, Eren was willing to sacrifice himself and would have given his abilities back to Paradis' royal family.
However, the king turned into a Titan himself after Historia refused to eat Eren and the Survey Corps had to defeat him. Eren kept his powers and would learn years later that he went back in time and told Grisha to kill the Reiss family. If Eren did use the Dragon Balls on this, he would have gone against his future self's wish.
4 He Would Wish For All Of The Soldiers To Survive The Battle At Shiganshina
When the Survey Corps fought the warriors at Shiganshina, there were a lot of new soldiers. However, only nine of them survived the battle. Most of them were killed by Zeke. Erwin was one of Zeke's victims and Levi had to make a difficult decision on who to save between him and Armin — who was burned by the Colossal Titan.
Eren and Mikasa begged him to bring Armin back while others thought that the commander should return. If Eren had the Dragon Balls, they could have both been saved, along with all of the other soldiers.
3 He Would Wish That The Titans Never Existed
Eren hated the Titans before he knew that his true enemies were humans from other countries. Before learning this, he would have wished for the Titans to not be around. This would have probably resulted in Ymir, the first Titan, to die when King Fritz had his followers hunt her down.
She wouldn't have connected to the Source of All Living Matter, been forced to have King Fritz's children, and gone inside of the coordinate for 2,000 years. Ymir Fritz suffered due to the Titans more than anyone, and even if he didn't know it, Eren could have saved her from all of that pain with this wish.
2 He Would Wish To Defeat All Of His Enemies
Eren has done a lot in order to defeat all of Paradis' enemies. He betrayed his friends and the military, manipulated his brother, and formed a group of Eldians to follow him, all so he could begin The Rumbling. All of the Colossal Titans inside the walls were unhardened and Eren led them to crush people to death.
When the Survey Corps and Warrior Unit caught up to him, he also brought back the previous inheritors of the Nine Titans to defeat them, only to lose the battle. If he had the Dragon Balls, all of this could have been avoided. He would have used them to kill anyone that attacked Paradis and could have spared the innocent people he had the Colossal Titans stomp on.
1 He Would Wish That His Friends Could Have Long & Happy Lives
The main reason why Eren has done everything he has was in order to give his friends the best lives possible. He cared a lot about them, even if it didn't always seem like it. As he only had thirteen years left to live after inheriting the Founding and Attack Titans, his friends all suggested that they become his successor, but he refused, letting them know that he wanted them to live for a long time and be at peace.
This was also one of the reasons why he created The Rumbling, knowing that their war would continue long after he died if he didn't. Even after he dies, this is one wish that he would want to make a reality.
