During Season six, Nick grew an ill-advised moustache, but soon got rid of it. He is seen throughout the series with dark hair that always stays relatively short and spikey. He is of average height and has a slim but muscular build. This comes through whenever he is chasing a suspect.
Nick has a natural empathy with the people affected by the crimes he investigates. Other members of the team believe that it is better to maintain an emotional distance. This difference in outlook is a source of much comment and occasionally raised voices.
Nick is chivalrous; while interviewing two girls at a wedding, he took off his jacket and gave it one of the interviewees. (Rashomama)
Nick can become emotional under intense stress: he nearly cried when being held at gunpoint (Who Are You), broke down and was on the verge of committing suicide when buried alive in a glass coffin (Grave Danger), and broke down once again in when discussing the death of the victim with Raymond Langston, and how he should have seen the danger signs over the year he had known her, and done something to prevent it (Turn, Turn, Turn).
Nick changed after he was buried alive. (Grave Danger) He lost his temper and physically grabbed and intimidated a suspect he believed had knowledge of where a young girl was hidden. (Gumdrops) Afterwards, Sara told Nick that she believed that six months ago, he wouldn't have lost control in the room with the suspect like that.
Nick is dating the nurse he met in the hospital after saving a man. (Seeing Red)
Nick specializes in hair and fiber analysis. 
After Grissom leaves; Nick takes a course to become the lab's "bug guy".
Nick seems he had a very close relationship with his father, Bill Stokes, as they had nicknames for each other, Poncho for Nick and Cisco for Bill, most likley from the famous film, the Cisco brothers. It is seen that he is very protective about his mother, but definitely not a mothers boy.
Nick's father, Bill Stokes, is a judge. (Grave Danger) His mother, Jillian Stokes, is a lawyer, and Nick is the youngest of seven children. He has at least one brother. (Revenge Is Best Served Cold)
Nick is from Austin, Texas, where he grew up playing football. 
When he was nine years old, Nick had a traumatic experience, most likely molestation, at the hands of a last-minute replacement babysitter. He never told anyone until 2001, when he confided in Catherine Willows in episode 203, Overload. Because of this Nick has trouble investigating crimes against children.
Nick was a member of a fraternity when he was in college and is familiar with fraternity hazing, as he tells a fraternity member in the fourth episode, Pledging Mr. Johnson.
Stokes spent his first three years out of college in the Dallas police force, then transferred to the Dallas crime lab, spending one year as CSI Level 1 before transferring to the Las Vegas crime lab. 
Grave Danger, Part 1
Nick was nearly killed when he was incapacitated using ether, put inside an acrylic glass coffin and buried underground while an installed web camera provided visuals of his plight to his coworkers who were initially helpless to save him.
Grave Danger, Part 2
It turned out Nick was the target of an attack on the CSI team by a man whose daughter was implicated in a murder case. The deathtrap culminated when fire ants entered Nick's coffin and attacked him. Although Nick was in horrific agony in this ordeal, the ants gave Gil Grissom (who is an insect expert) a vital clue that allowed the team to determine his location. The box was also rigged with Semtex explosive. Thus informed, Nick's coworkers rushed to his rescue and managed to save him from the brink of death.
In the season 9 premiere, For Warrick, Nick is shown to remain calm and composed upon learning of Warrick's death. However, later, when confronting a wounded Undersheriff McKeen—Warrick's killer—the undersheriff goads an increasingly angry Nick into attempting to shoot him as well. Jim Brass hears a shot fired and arrives on the scene to find McKeen still alive and wounded, and a once-again calm Nick stating coldly that "[he] missed".
In "The Grave Shift", after Catherine turned down the offer to move into Grissom's now-vacant office, she offered it to Nick—who accepted, after some thought. He in turn decided to share the office space with Greg Sanders and Riley Adams, who are shown unpacking alongside him. Additionally, Grissom's infamous fetal pig in a jar has been placed in there as well, by Hodges.
Nick is promoted to Assistant Supervisor on the Grave Yard shift after Sara advises Catherine that she needs a number two. Nick is also seen dealing with tarantulas, and is shown taking Grissom's old tarantula under his care.
Nick was shot with a shotgun by Dr. Jekyll. He played dead on the floor until he was able to pick his gun off the floor, and then he killed Jekyll with a series of tightly grouped shots to his chest.
Nick meets Jeffrey McKeen again when he is connected to a triple murder. When he turns out to have corrupt cops inside the LVPD on his payroll, it brings up memories of Warrick's death for Nick, who announces to Greg and Sara that he intends to quit.
Karma to Burn
Having quit the lab, Nick decides to celebrate by getting drunk outside of a liquor store, only to end up in jail after an altercation between him and two police officers. Sara finds Nick and asks him how many beers he's had tonight. She tells him he can quit tomorrow if he still wants to, but not tonight.
After working with the team, he manages to rescue Kaitlyn Russell from Paul Kimball, a police officer on McKeen's payroll. Nick then decides that he wishes to stay with the team again and is welcomed back.
Nick is usually affable and gets along with his co-workers. He considered co-worker Warrick Brown a very good friend. After Warrick died, Nick even put together a college fund for his son. (Turn, Turn, Turn)
He shares a good-natured relationship with former supervisor Gil Grissom, almost that of father and son, or mentor and apprentice. When Raymond Langston, the newest and least-experienced member of the team, joined the team, Nick acted as his right-hand man, giving him tips and helping with investigations.
A sort of running gag throughout the series seems to indicate that whenever Nick gets with a woman, misfortune befalls someone else. In Boom, he slept with a prostitute called Kristy, as we find out when Nick tells Gil Grissom as Nick is a suspect in the murder of Kristy as she died later that early morning, as Jack her Former Boyfriend killed her, Nick quotes "I took off around 4"Nick and co-worker Catherine Willows go to a club together. Shortly after Nick hooks up with a woman at the club, Catherine is drugged and abducted. During breakfast with the team at a diner, Nick eyes a pretty waitress and stays behind to get her number while Warrick Brown leaves. (For Gedda) Shortly after, Warrick is murdered.
It is often mentioned that Nick is something of a ladies' man. He got a phone number from a female suspect he interviewed at a wedding in Rashomama. However, the only onscreen romance over the course of the series was the brief affair with Kristi.
Nick: (to Grissom) How come whenever you talk about bugs, people say you're a genius, but when I talk about birds people say that I watch too much TV?
Nick: (to Sara) You can't have a career without a job.
Nick: There's a sucker born every minute.
- Grissom: Yeah, and they all come to Vegas.
Nick: (to Sanders) What's up, Einstein? Got anything there?
Nick: (to Sara) You took a shower... but you still smell.
