Mass Effect Legendary Edition brought back the acclaimed science fiction games in an updated version. Along with graphical improvements, BioWare added all DLC content to the games and made a number of gameplay updates. The trilogy might show its age at times, but it is definitely worth playing.

You might feel like your squadmates are your friends after the many hours the games demand to be finished. Shepard accompanies them in dangerous situations, suicide missions, adulthood rituals, and so many other things. One of the things that make the characters so good in Mass Effect is that they are not perfect. Squadmates are flawed, just like any human being in real life.

21 Kaidan Alenko: L2 Implants

Mass Effect 3 Legendary Edition Kaidan Alenko

Unlike many other biotics you'll meet throughout the game, Kaidan has constant migraines due to his implants. The technology that was implanted in Kaidan is the controversial L2.

The L2 implants have the potential to make biotics way more powerful than the old L1. However, they are also much more dangerous. Many biotics who had the L2 suffered from brain damage. Kaidan is lucky for having only migraines from using it.

20 Wrex: The Genophage

Mass Effect Legendary Edition Urdnot Wrex

The genophage is a genetic disorder designed to prevent the krogan from reproducing due to their actions against the citadel species. Wrex is wholly devoted to his people and making sure they will have a future.

This is precisely what makes it so difficult for him to be cold and rational when he has any chance to save his people's future. During the first game, Wrex gets into a severe argument with Shepard at gunpoint. All because Saren potentially had a cure for the genophage.

19 Ashley Williams: Family History

Ashley Williams Mass Effect

Ashley is a Williams, which is a big deal in the Alliance. She is the granddaughter of General Williams, the Systems Alliance Commander of the Garrison on Shanxi. He fought during the First Contact War, but the results of his campaign were not satisfactory to many Alliance members.

General Williams is known for being the only human commander to surrender to the turian. Although his decision was focused on saving lives, the event haunts the family name and has always troubled Ashley.

18 Garrus Valkarian: His Morals

Mass Effect - Garrus Vakarian's gaze

Due to his father's influence, Garrus became a by-the-book person. He was even one of the many turians who could have become a spectre, but his candidacy was blocked by his father who despised the spectres due to their extralegal freedoms. He seems to be completely fine with passing on that career, though.

RELATED: Mass Effect Legendary Edition: Dragon Age Easter Eggs

His father's influence on him is pretty clear throughout the first game, but Garrus ends up becoming someone with a strong moral compass instead of a legalist. In order to chase Saren, he quit Citadel Security to follow Shepard and learn how spectres work. At some point, he concluded that something being legal does not always mean it's right.

17 Liara T'Soni: Being A Benezia's Pureblood Daughter

Mass Effect Legendary Edition Liara Tsoni

Everyone's favorite asari archeologist, Doctor Liara T'Soni, is the daughter of Matriarch Benezia. Liara was raised well, but she was a pureblood. This caused her mother to hide information about her father. Most likely due to her being ashamed for having another asari as a partner.

Liara ended up developing an agreeable personality and decided to study the protheans as a way to rebel against her mother. Eventually, nobody trusted her for being the daughter of Saren's right-hand woman. Due to losing her mother, Liara valued friendships much more, causing her to become a completely different person when her friend Feron was kidnapped.

16 Tali'Zorah Nar Rayya: Her Species' Weakness

Mass Effect Tali

Tali is a quarian and possibly the best companion of the trilogy. Quarians are a species of humanoid usually placed between humans and turians. Quarians are nomadic people with excellent technological skills. The species lost their homeworld to sentient robots they created for manual labor.

Quarians have a fragile immune system. That comes from centuries of them living in sterile environments. They constantly need special suits, which means any wound is more dangerous to Tali than to any other squadmate.

15 Kasumi Goto: Her Kleptomania

Mass Effect 2's scene with Kasumi Goto

Kasumi Goto is a master thief that specializes in infiltration, sabotage, and extraction. Following the character's theme, her loyalty mission is a heist. Being this kind of person, Kasumi might attract trouble in many ways.

She has had problems with both legal forces and crime lords in her path. This is something that won't simply go away as she will always be a thief. Besides, it is implausible that she will ever turn herself in.

14 Grunt: His Age

Mass Effect 2 Grunt holding shotgun

Grunt is a huge, powerful krogan that was made in a lab. He doesn't look exactly like the others of his kind, but he does behave like them. Since he is a krogan who was bred to be a super-soldier, Grunt constantly desires violence.

Grunt is a very young krogan. In a species that can live a thousand years, he is a toddler. His lack of experience can get in the way sometimes. He knows so little about the world and himself. Grunt didn't even know what was happening to him when he was changing into an adult.

13 Thane Krios: Kepral's Syndrome

Thane's skills are known throughout many systems. He is rumored to be the best assassin in the whole galaxy. Unlike most assassins, Thane prefers to kill his victims up close. After doing so, he asks for forgiveness.

12 Jack: Her Temper

Jack is one of the most powerful human biotics. However, she is also a traumatized victim of abuse who has never had any help throughout her life. Jack developed a dangerously unpredictable temper. She became a wanted criminal with many severe crimes on her record.

Jack is so dangerous that Shepard finds her in cryo-sleep imprisonment. At some point, if you are pursuing a romantic relationship with her, Mordin will try to make the commander reconsider. He warns Shepard that Jack can easily kill them either accidentally or on purpose.

11 Miranda Lawson: Her Father

Miranda is a Cerberus Operative who has the best genes that money can buy. She is a powerful biotic and a great gunslinger. Lawson is intelligent, athletic, and beautiful. Yet, she does not take credit for any of her accomplishments. Miranda attributes her success to her genes.

Miranda's father never allowed her to have friends or any social interactions at all. Also, he never showed that he was proud of her. He was constantly pushing her to be better and was never happy with the results.

10 Legion: The Geth's Rejection Of Him

Mass Effect 3 - Legion's ashamed

As an independent geth unit, Legion developed a personality and became Shepard's good friend. Even Tali might be happy to see him in Mass Effect 3. However, the geth branched into two different factions.

RELATED: Mass Effect: Who Controls Different Parts Of The Milky Way?

Since the reapers only harvest biological life, a faction of the geth sided with them for self-preservation. After being attacked by the quarians in Mass Effect 2, both factions decided that it was the best choice. Legion disagreed, causing his people to keep him restrained.

9 Zaeed Massani: His Personality

Mass Effect 2 - Zaeed is left for dead

Zaeed is a character that not many people seem to like. He is a criminal that takes pride in not caring about other people's lives. In order to take down Vido, Zaeed is willing to let many innocents die in a fire.

During his loyalty mission, you have to choose between helping Zaeed to catch Vido or saving innocents. Zaeed is so focused on his revenge that Shepard will lose his loyalty by stopping to put out the fire. His loyalty mission can end with Shepard leaving Zaeed to die in the fire he caused.

8 Samara: The Justicar Code

Mass Effect 2 Samara During Her Loyalty Mission

Samara is nearly a thousand years old. She is an asari justicar who is skilled in combat. Although justicars rarely leave asari space, Samara hunted down her daughter for killing many people. She does not ever ignore the justicar code.

This code makes her chase her daughter until she is found, and she also uses it as an argument not to pursue a romantic relationship with Shepard. It can also cause her to commit suicide so she won't have to kill her other daughter.

7 Morinth: Being An Ardat-Yakshi

Morinth Screenshot in Mass Effect 2 Seducing Shepard

Morinth is a pureblood who is the daughter of a pureblood. Her mother is Samar, the asari justicar. Pureblood asari are more likely to be Ardat-Yakshi, and Samara had three daughters with this genetic condition.

Ardat-Yakshi, "Demon of the Night Winds," is the name of a genetic condition. It causes an asari to overpower a mating partner's nervous system, killing them in the process. As a result, the Ardat-Yakshi becomes stronger, smarter, and hunted by justicars.

6 Mordin Solus: His Guilt

Mass Effect Legendary Edition Mordin Solus

The krogan, being a resilient species, started developing a resistance to the genophage. In order to prevent the krogan from massively increasing their population, the salarians worked on a way to modify the genetic disorder.

Mordin worked in the modification of the genophage, which eventually caused the krogan to become a near-extinct race. Although Mordin believes it was necessary, he never stopped feeling guilty. He might even sacrifice himself to revert the genophage in Mass Effect 3.

5 Jacob Taylor: His Lack Of Patience

jacob taylor mass effect

Jacob could not stand the bureaucracy that guided the Alliance's actions. That was his excuse for joining Cerberus, even though the organization is very suspicious. He bragged about being able to take immediate action when something happened to a human colony.

RELATED: Mass Effect: Things About Commander Shepard That Everyone Forgets About

If Jacob was female Shepard's love interest in Mass Effect 2, he loses interest in the commander after the suicide mission. In Mass Effect 3, he acts surprised when she wants to rekindle the relationship and says: "Did you expect me to wait forever?"

4 Javik: Being The Last Of His Kind

Mass Effect Legendary Edition - Javik is surrounded by primitives

The last living prothean considers himself surrounded by primitives. Communication is not as advanced as it was back in his time. To Javik, the dominant races are not advanced enough, the current technology is mediocre, and the galaxy is not prepared to fight the reapers.

Although constantly annoyed by the underdeveloped cycle, Javik is willing to help them take down the reapers. His pragmatic way of thinking makes him do his best with what he has. However, it does bother him that his revenge is in the hands of primitive species.

3 EDI: Being An Artificial Intelligence

mass effect EDI

EDI does not have a body, although she steals one at some point in Mass Effect 3. EDI's mobile unit makes Tali a bit concerned when she sees it. Since the geth pushed the quarian away from Rannoch, the Council passed laws that made Artificial intelligence illegal.

Because of legal matters and possible bad reactions to her existence, EDI is always at risk. Also, much like Legion, EDI does not always understand the way biologicals species think.

2 James Vega: He Overcompensates

James Vega near ship models

Although he is an experienced soldier with good morals, James Vega did not know much about politics. In fact, he was surprised by Udina's coup on the Citadel. This led him to adopt a "shoot first, ask later" behavior towards politicians.

Due to the guilt of choosing intel on collectors instead of saving a colony, Vega is constantly trying to do more. The undying memory of the occurrence caused him to be needlessly reckless at times.
