The strange and twisted drama that is Killing Eve will soon be coming to an end with its fourth and final season, so it's time to take a look at every character that made the show worth watching. While Villanelle and Eve's chemistry was the epicenter of the show, all the side characters like Dasha, Hélène, and Irina made the show a treat to watch.

In fact, all of these players formed an important part of the series, even if many of them were disliked by fans because of their personalities. A lot of them had the potential to have larger stories and get more screen time, just like a main character would.

Dasha Duzran

Dasha leans against a pillar in Killing Eve.

Villanelle's mentor and creepily good killer, Dasha, was an intriguing character to say the least. Fans saw that her story began when she was a young girl, practicing her sport. However, she was, even at a tender age, lethal and forthcoming when it came to murder.

She was happy to murder other kids with chalk powder and make a spectacle of it, and that was just the beginning of her "career." It would be super interesting to see what her life had been like, including her kills and her relationships. She may not have been a likable character on Killing Eve, but she was definitely a good one.

Nadia Kadomtseya

Nadia catches Villanelle by the collar in Killing Eve.

Fans debate about which character Villanelle should end up with, but they forget that she had a past, and that included Nadia Kadomtseya. While it was uncertain if Villanelle had real feelings for Nadia, she definitely conned her into believing it not once, but twice.

Nadia was also an assassin, just like Villanelle, and for someone like that to have a human connection was unusual. The story of how she came to be in the same place as Villanelle, and what their relationship was like, would draw the attention of many viewers.

Aaron Peel

Aaron Peel in Killing Eve.

The boss of Pharaday, Aaron Peel was no ordinary CEO. He was a seriously frightening and convoluted personality, and definitely capable of world domination. Peel had all the makings of a big, bad villain intent on taking over the world.

His controlling tendencies were very telling of his nature, with both "Billie" and his surveillance cameras everywhere. Villanelle may have ended him, but he took many dark secrets to his grave which fans would have loved to uncover.

The Ghost

Eve interrogates the ghost in Aaron Peel in Killing Eve.

Another hired killer, The Ghost appeared very briefly in the show, but she left an indelible mark on fans. She murdered for money and luxuries, and Aaron Peel was her last client when he put out a hit on his own father.

The Ghost was different from the others in the way she operated: she was stealthy, extremely meticulous, made no messes (unlike Villanelle and Dasha), and even had a family of her own. She was adept at keeping up her double life, which absolutely makes her worthy of being a main character.

Hélène

Killing Eve's Helene (Camille) Cottin hugs Villanelle (Jodie Comer)

The Twelve is a shadowy organization, and the only thing that fans know about it is that it hires killers like Villanelle (the best character on Killing Eve) to carry out hits on important people. So, meeting Hélène, one of the higher members of the Twelve, was nothing short of fascinating.

She too had a daughter and mother, which made her another deadly lady who managed to lead dual lives, which would seem impossible otherwise. Her inclusion and ascent into the organization would have been a rocky road, for sure, and fans would love to find out just how she managed to reach that level. Her personality was also warm and cold at the same time, and she carried an enigmatic aura around her.

 Irina

Irina outside in a coat in Killing Eve

Konstantin's daughter was a spitfire, and her presence just brightened up the television screen a bit further. Sassy and outspoken, she was unafraid of anything, including her father. In fact, the young lady had run Konstantin over with her car, which was pretty scary but epic when viewers actually saw her in action.

She was defiant, stubborn, and fearless, and even being around Oksana's craziness didn't faze her. In fact, she could match the anti-hero's energy equally, having screaming matches with her as they walked down deserted roads. Irina was definitely going to grow up to be a memorable woman.

Elena Felton

Elena Felton in Killing Eve

Eve's young secretary was no ordinary pencil pusher. She worked at the MI5, but had plans to become a spy and work with intel that nobody else had. So, when the opportunity came to join Eve and Bill at MI6's secret operation, she immediately agreed.

Elena was efficient, smart, and resourceful, which meant that she could find information on just about anything that Eve wanted, whether it was DNA, locations, or phone taps. Elena had the potential to go into the field or become one of the greatest off-site spies ever until she withdrew for her safety.

Gemma

Eve meets Niko's new girlfriend Gemma

In a Killing Eve scene that fans did not see coming, Villanelle got rid of Niko's potential girlfriend Gemma, which was shocking to say the least. While Gemma was irritating, she had a bit of a plotline going as the girl who had always admired Niko from a distance but couldn't do anything about it because he was married to Eve.

Gemma's dreams of being with Niko were finally coming to fruition before Villanelle finished her off. She could have been a great foil to Eve in future seasons, but that was cut short.

Anna Aanmokoba

Anna and Eve in Killing Eve

Besides Eve, Anna was probably the only other person for whom Villanelle had feelings. Anna had quite a story, which began when she met Villanelle in college when she taught her. Her initial sympathy turned to romantic love, which ended in tragedy for Anna's husband.

Anna was extremely unique, and fans would love to see what made her fall in love with someone like Villanelle, much like Eve's plot. Her earlier life and life during and after meeting the assassin made her the main character for sure.
