Chrollo is a Specialist with the main skill of stealing other people Nen abilities. His primary skill called "Skill Hunter". The stolen Nen ability of other Nen users is then stored inside a book called "Bandit's Secret". This book needs to be open during the time he is using the stolen ability. There are four conditions that needs to be fulfilled to enable him steal someone's ability. These conditions are as follows.
The second ability he developed later in the anime is "Double Face". With this ability he can place a bookmark in his book for the ability he wants to use without keeping the book open to that page enabling him to either be able to use his both hands in combat while wielding the stolen ability or it can enable him to use more than one stolen ability at the same time.
Nobunaga is one of the six members the Troupe started with and he has number #1 inside the spider tattoo. He is ranked Ninth among the Troupe in terms of physical strength based on arm wrestling. He was friends with Uvogin even before they both joined the Troupe. When Uvogin got killed he was the most affected, even shedding tears for him in front of Gon and Killua and promising to kill whoever killed his friend. Nobunaga was fond of Gon and he wanted him to join the Troupe to become his partner instead of Uvogin.
Nobunaga is an Enhancer and a master swordsman. His Nen abilities are still to be discovered. During the Chimera ant, few members has demonstrated their Nen abilities fighting the ants; however Nobunaga wasn't part of the group who came back to Meteor City.
The spider tattoo on Feitan body is not revealed yet. Since the Troupe has been formed in Meteor City he has been #2 of the Spider. Feitan is ranked fifth based on arm wrestling. Feitan is expert in torture which makes him the best Troupe member when it comes to interrogating. Feitan is one of the member who strictly followed the rules of the Spider and cared about the spider as a whole and prioritize the Troupe existence above any member including the head. He eventually became the interim leader of the Troupe when he defeated Zazan (squadron leader of Chimera ant) who came into Meteor City.
Feitan is very skilled fighter with strength, agility, speed, and a strong Nen. His Nen falls in the Transmuter category. in the past his Nen ability almost killed some of the Troupe members who wanted to watch it. When he activated his Nen ability against Zazan the other Troupe member ran away from the location so that they will not be caught up in his ability. The activation of his Nen ability is triggered by anger and being injured. The strength of his ability is directly related to the amount of damage he has taken.
Machi holds #3 of the Troupe and she is sexth at arm wrestling. She is also one of the founding members of the Troupe. She is very loyal to their leader Chrollo. Machi's hunch is usually correct even when there is no evidance that support her hunch. When they captured Gon and Killua, even though both didn't know Kurapika is the one the Troupe were after and both of them has been scanned by Pakunda's ability, still Machi had accurately speculated they are connected to the chain user. Her hunch is trusted by the Troupe and their leader.
Her Nen falls in Transmutation and one of the first Nen abilities to be revealed from the Troupe members. Hisoka was fascinated by her Nen Stitches technique. Her two known abilities are:
Little is known about #4. Hisoka defeated #4 to replace him in the Troupe. His Skills and abilities are still unknown.
Hisoka is very strong, he ranked third in the Phantom Troupe in terms of physical strength which is based on arm wrestling. Hisoka has no interest in the Phantom Troupe other than his plans of fighting against their leader Chrollo. He defeated #4 of the Troupe to take his place. In the hunter exam he has failed the first time because he almost killed one of the examiners that he didn't like. In his second attempt he attacked the first examiner to confirm he is real. During that hunter exam he met Gon and became very fond of him. During the hunter exam it was evident that he is the strongest applicant. Though it's still not known who would win if Hisoka and Illumi Zoldyck would fight.
Hisoka is a very strong Nen user. He even devised his own way of determining the person's Nen category based on their personality. using his method he accurately guessed Gon's and Killua's Nen category. He also came up with "memory overload" concept. Hisoka's Nen abilities are simple yet very powerful and hard to deal with as admitted by Nobunaga. His Nen ability has been named after his favorite candy and gum from his childhood. Hisoka falls in the Transmutation category with and has following abilities:
This is the youngest child of the Zoldyck family, he is only 10 years old. He supported Illumi in killing the Mafia's Ten Dons. Also on another occasion he helped Illumi leave the phantom troupe hideout when he was covering up for Hisoka's absence. Kalluto has a very good relationship with his mother. As the rest of the family members, he is resistance to most poisons and have great strength and agility with training of assassination techniques. eventually he joined the phantom troupe replacing Hisoka as #4.
Kalluto is a Manipulator. He is well trained for Nen as demonsterated with the encounter against the Chimera ants. Two abilities are known so far.
Phinks ranked second in terms of strength and he hold #5. It's not clear if he was part of the founding members or not. Phinks usually accompanied by Feitan. Like most of the Troupe member, Phinks as well is from Meteor city. He was part of the group who came back to Meteor city to rescue it from Chimera ants. He is one of the loyal members to their leader and one of the members who prioritize the existence of the Troupe above all members. He considered Pakunda's actions as betrayal to the Troupe even though she only wanted to save their leader Chrollo. Himself and Feitan was ready to attack Pakunoda, Machi, and Kortopi to stop them, kill the hostages and then go after the chain user.
Just like other members of the Troupe, he possess immense strength, agility and speed. He is also expert in trailing. He tailed two of the Troupe members without them noticing him. As for Nen he is an Enhancer and he is very skilled Nen user with theoretical knowledge of Nen. There is only one of his Nen technique has been demonstrated when they fought the Chimera ants.
Shalnark is #6 of the Troupe or #9. He is one of the Troupe members who has a hunter license. His strength is ranked tenth in terms of physical strength. In Pakunoda's flash back for the beginning of the Troupe he wasn't there but he was refereed to as a founding member. Shalnark was on ph and Feitan side to go after the chain user even if it means the death of Chrollo. This entails he also value the existence of the spider over each and every member including the head. He even value Pakunoda and Shizuku over his life because their abilities are rare unlike his own talent which is replaceable, therefore their abilities are more important for the Troupe.
Shalnark is smart and able to evaluate the situation very well. With his henter license he can have access to resources and information that is very useful to the mission they are trying to accomplish, as when he helped Uvogin in tracking down the chain user. Shalnark knows that his ability is not unique and can be replace in case something happens to him, however his ability has been borrowed by their leader Chrollo in his preparation to fight against Hisoka. After the fight of Chrollo and Hisoka which ended with the death of Hisoka and him coming back to life, Hisoka swore to kill all the Troupe members. Shalnark was the second to die by the hands of Hisoka.
When it comes to Nen. Shalnark is in the Manipulation category with the following abilities:
Franklin is one of the founding members of the Troupe. he is the #7 limb of the Spider and ranked fourth in physical strength. His loyalty to the Spider is evidence in his speech to the other troupe members, when he stated that they would kill any Troupe member that is controlled by the chain user and then will rebuild the Troupe again to ensure the survival of the Troupe and it's prioritized above any of the members including their leader. He is strictly abiding by the rules to maintain the Troupe survival regardless of who might die in the process.
Franklin is originally from Meteor City as all the founding members are; However, he wasn't part of the group who came back to Meteor City to rescue it from Chimera ant invaders. He was part of all other Troupe endeavor such as: Kurta Clan Massacre, Massacring the Mafia at the auction, joining other Troupe members in Greed Island.
Franklin is physically strong, he ranked fourth among the Troupe. Regardless of his huge body, Franklin possess significant speed as well. He is also very skilled Nen user who falls in the Emission category with his main ability "Double Machine Gun" that has been shown so far.
Prior to the start of the Anime. #8 of the Phantom Troupe was killed by Silva Zoldyck who was hired to kill #8. The contractor is unknown and why they wanted #8 dead still unknown as well. Silva Zoldyck had to fight Chrollo in the process of assassinating #8. Once he got killed he was replaced by Shizuku Murasaki.
Shizuku holds #8 of the Spider. She is not one of the founding members. She joined the Troupe after the death of the previous #8 member by the hands of Silva Zoldyck. Her strength ranked twelfth among the Troupe Members. She lost to Gon not because she is weaker than him, it was due to using her right hand. If she used her strong hand, she would have won. She did not join the Troupe by beating one of it's current member, but rather by Chrollo. Either one of the current members nominated her or Chrollo is the one who brought her into the Troupe. She also has the habit of forgetting things. Once she forget something she would never remember it again as when she lost to Gon and the Troupe member tried to remind her of it. She just didn't remember that event.
Shizuku possess strength, speed, and agility like other Troupe members. She also has one of the rare Nen powers which are hard to replace upon her death as stated by Shalnark. Her Nen falls into Conjuration category with one main skill:
Pakunoda was #9 or #6 of the Troupe. Physically she ranked eleventh among the other members. She is also from Meteor City and one of the founding members of the Troupe. She remained loyal to the Troupe and to the Leader, but she prioritized the life of the leader Chrollo above the Troupe existence which has been considered a betrayal to the Troupe. Her last prayer before her death after conveying her memories to the founding Troupe members was "Please. Let me... be the last..." hoping that she would be the last one who get killed and the life of the rest will be spared.
Pakunoda is strong with advanced speed, agility and endurance to pain. She also possess one of the rarest abilities ever and very dangerous ability to the enemies. she can read memories. according to her she can get the purest of the memories even if the enemy try to tamper with it. Her Nen is within the Specialization category with the following developed abilities:
Bonolenov is #10 of the Spider and he ranked eighth in physical strength among the Troupe members. He is not one of the founding members of the Troupe. Bonolenov entire body is covered with bandages to cover the holes in his body. His body without the bandages and back story has been revealed during his fight against the Chimera ants as he was part of the Troupe Members who came back to Meteor City to rescue it from the ants. It's still unknown how he came to join the Troupe.
Bonolenov is a graceful warrior who came from the Gyudondond Tribe which he takes pride in it. The entire tripe has been eradicated. He is very skilled fighter and strong with enhanced speed and agility. He is also a skilled Nen user; However his Nen category is not confirmed yet. His two abilities that has been shown falls into Conjuration category while the third ability is not scene yet and it not known which category does it belong to. By employing the holes in his body, with dancing moves that he inherited from his tribe he can play music through the holes in his body. Each song he create has a different effect:
Uvogin holds #11 of the spider, and by far he is the strongest one among them physically. He ranks first above all Troupe members. He is the first Troupe member we get to see his Spider tattoo with #11 inside it. He is also one of the founding members of the Spider and came from Meteor City. He was friends with Nobunaga even before both joined the Troupe. He demonstrated a great loyalty to the Troupe and their leader. Even in his last moments he preferred death over selling out his comrades. To avenge his death the other Troupe members massacred the Mafia by the orders of their leader Chrollo.
The Troupe attacked the auction to steal all the items; However they didn't find anything as it all has been taken into a safe place prior to the Troupe's attempt. The Troupe members escaped in hot-air balloon which has been shoot down by the Mafia. Uvogin told the other Troupe member to not interfere. He single-handedly took care of the Mafia surrounding them and also defeating three of the Shadow-beasts alone. He was insulted when he was compared to a tank before he got shot with a bazooka. For Nen he is an Enhancer with the following Nen ability:
Another ability has been shown during his fight against the shadow beasts that is enhanced by his Nen is simply shouting, which has the power to deafened the other troupe members have they failed to cover their ears in time. Even by covering their ears, some Troupe members complained that they would have headache now because of it.
Illumi is the eldest son of Silva. He was introduced as Gittarackur during the 287th Hunter exam then his true identity was revealed during his fight against his younger brother Killua in the final stage of the hunter exam. Illumi used the needles to change his appearance and disguised as Gittarackur during the exam so that Killua would not recognize him. Illumi had two purposes to participate in the hunter exam. the first is because his next assassination job requires a hunter license and the second is to keep an eye on his brother Killua. during the exam Illumi teamed up with Hisoka.
Apart from his physical strength, agility, and resistance to poison as the rest of the family, his Nen is very strong and he is definitely falls in the Manipulation category of Nen as all of his Nen abilities are in that category. Below is a list of his Nen abilities:
Illumi performed multiple jobs as an assassin. Not all of these jobs required him to kill someone as when he took Hisoka's place, his job was only to fool other troupe member into thinking that Hisoka remained at the hideout and never left. another job was when he was hired by Chrollo (the head of the spiders) to kill the Mafia's ten dons at which he teamed up with Maha and his youngest brother kalluto to successfully complete the mission.
Kortopi was #12 of the Troupe, and he is the weakest among them in physical strength holding the last position in arm wrestling. His face was never seen as his hair would cover this entire face at all the time. He is very loyal to their leader Chrollo, he even allowed him to borrow his Nen ability when Chrollo was preparing to fight Hisoka. He is not a founding member and it's unknown when did he exactly joined the Troupe. He eventually died by the hands of Hisoka.
Eventhough he is ranked the weakest in the Troupe he is still strong enough to be part of the Phantom Troupe. Kortopi's Nen type is Conjuration and he have a very useful ability with many applications.
