There have been many characters throughout the Dragon Ball Saga that are ripe pickings to put on the Dungeons & Dragons moral alignment chart. For those that may not know, the D&D moral alignment chart is a 3x3 grid with rows for "good, neutral, evil", and columns for "lawful, neutral, chaotic," and pretty much every fictional character on earth can be categorized by these metrics.
The countless characters throughout the series number way too many to fit on out list, so we're just going to focus on the main cast of the Dragon Ball saga and a couple of major characters. Here's the D&D moral alignments of the main cast of Dragon Ball.
10 Krillin: Neutral Good
Let's start this list off with Krillin, Goku's best and most faithful friend. Krillin's been by Goku's side nearly since the beginning of the original Dragon Ball and they trained side-by-side under Master Roshi.
Krillin is a neutral good character. He does the best amount of good that he can do and strives to help others. The fact that he becomes a police officer in Dragon Ball Super is proof of his good-natured personality. He may not be the strongest character in the series, but that's never stopped him from trying to help others and stop impossibly dangerous threats.
9 Beerus: Lawful Neutral
Beerus, the feared God of Destruction of Universe 7, is a clear choice for Lawful Neutral. As a God of Destruction, Beerus has wiped out entire races and planets, but he did so only because those races and planets would have put the development of the universe at risk.
Beerus is more like a force of nature than anything else, and destroys worlds because he must, not out of some malicious plot. He also has a set of rules he must abide by as the God of Destruction, such as being forbidden to travel through time, and he can't go around destroying as he pleases. Beerus doesn't much care for the affairs of everyone else, he's just got a job to do.
8 Androids 17 & 18: True Neutral
Both Androids 17 and 18 are true neutral characters, even though they didn't start that way. Sure, they both started out as enemies of the Z-Fighters, but they're a far cry from villains they were in Dragon Ball Z. Now, they really just live for themselves.
Android 18, for example, started a family with Krillin and just wants a nice, quiet life with her family. She'd prefer not to get involved in fights and only joins the Tournament of Power because of the cash prize that Goku promised. And Android 17 just wants a peaceful life caring for animals. The Android siblings basically just do what seems like a good idea to them.
7 Trunks: Neutral Good
We're focusing on Future Trunks for this entry, and we have him pegged as a neutral good character. Trunks comes from an alternate timeline where the Androids murdered all the Z-Fighters and created a Hell on Earth, prompting him to travel to the past to stop the Androids before they could do any damage.
Even though Trunks is vengeful and full of rage, he was trained by a future version of Gohan and as such, has many of the same ideals as his mentor. That being said, there are times when Trunks' vengeance bleeds through, which is the only thing stopping him from being a lawful good character.
6 Frieza: Chaotic Evil
When putting Dragon Ball characters on the D&D moral alignment chart, people usually put Frieza as a lawful evil character, but we want to offer a different take. We have Frieza pegged as more of a chaotic evil character, and we'll explain why.
The main reason people put Frieza down as lawful evil is because he's the leader of a galactic empire, and while that's true, it by no means makes him lawful. Frieza is arbitrarily and unpredictably violent, and he kills on a whim, even his own subordinates. He may be an emperor, but he doesn't follow any laws, he does whatever he wants as long as it means gaining more power.
5 Piccolo: Lawful Good
Piccolo, aka Gohan's real dad, started out as Goku's antagonist but he quickly became one of the best and most beloved character of the series. An alien from the planet Namek and one of the last of his race, Piccolo is a lawful good character.
Of all the characters in the main cast, Piccolo most embodies the ideals of justice. He's stern, precise, and honorable, something that made him a favorite among fans. While training Gohan during the Saiyan Arc, Piccolo develops a bond with the boy and becomes a father figure to him and passes on his ideals to Gohan, who we'll get to soon enough.
4 Bulma: Neutral Good
Bulma has been around from the very beginning of the Dragon Ball series and she's Goku's first friend. She may have had shot at Goku when they first met but trust us, she's a morally good character, a neutral good character to be specific. Bulma has a fiery personality, so much so that she has gained the respect (and some fear) of Beerus, the God of Destruction.
She demonstrates her neutral good alignment using her skills as a brilliant scientist. For example, in the Goku Black arc of Dragon Ball Super, Bulma provides capsules full of food to give to the survivors of the future. Bulma is always ready to give a helping hand, not because she wants to get something out of it, but just because it's the right thing to do.
3 Gohan: Lawful Good
If Piccolo isn't the epitome of justice, than Gohan definitely is, which should be no surprised as he was trained by Piccolo. Gohan is Goku's eldest son and a clear cut lawful good character. Being Goku's son, it's no surprise that Gohan went into the family business of beating supernatural threats to a pulp, but that's not to say that Gohan enjoys fighting. Far from it.
Gohan usually prefers to avoid violence, really only fighting when he absolutely must to uphold order and justice. Gohan's sense of justice is so strong that, love it or hate it, he becomes the Great Saiyaman, a superhero that battles injustice.
2 Vegeta: Chaotic Good
Vegeta may seem like a crotchety, aggressive, and short-tempered Saiyan, but he's a softy at heart. When he was first introduced, Vegeta was definitely more of a chaotic evil character but the years seemed to have chilled him out and we'd now call him chaotic good.
Since becoming a family man, Vegeta developed a good heart and fights for good, but he does it his own way. He doesn't much care for laws or expectations, he carves his own path. He's not one to worry about property damage when fighting an evil foe, but at least people are safe (mostly). He can be a bit too violent against enemies but you can tell he's a good person by how much he cares about his family.
1 Goku: Chaotic Good
Finally, we have Goku, the main protagonist of the Dragon Ball series. He's come a long way from being a child living in the woods, and through the years, we've come to see Goku as a chaotic good character (same type as Vegeta but in very different ways).
Because he can be simple-minded, you can almost say that he fights for good on accident. That's because his goal has largely been to become the greatest warrior in the universe and it just so happens that the ones best suited to test Goku's strength are usually the biggest threats to the world. Even so, there is genuine good in him, instilled in him by Grandpa Gohan. He's the defender of Earth but he does it with his own special brand of strange.
