Fitzroy Avery Vacker

Fitzroy Avery Vacker, "Fitz", or "Wonderboy" as Dex calls him, is a sixteen-year-old elf, as of Book 5, belonging to the Vacker family and lives in Everglen. He was a Level Four prodigy at Foxfire, a prestigious elf school in Keeper of the Lost Cities. In Exile, he became a Level Five prodigy. It was officially revealed by Shannon Messenger that Fitz's name is derived from Fitzroy. Along with his sister Biana, he is said to also be the first Vacker to attend Exilium, during his exile period in Neverseen.

Fitzroy means "son of the king/seeker of wisdom".

Physical Appearance
Fitz is tall and brunette, with breathtaking teal eyes. Sophie thinks he is very attractive. He is described as quite handsome. Marella also thinks he is very cute and has a crush on him, and he may have a crush on a particular girl. Fitz has the Vacker family's good looks. All the girls at Foxfire think he is enchanting and so have crushes on him. In Keeper of the Lost Cities, Fitz frequently runs his hands through his hair when he was frustrated, like his father Alden. In Neverseen, Fitz is shown to have "rather impressive" muscles. Dex calls him Wonderboy, meaning he is prepossessing as well as being perfect at everything else. He is also called the most charming boy at Foxfire, with his looks and his abilities, although he is perhaps in competition with Keefe for this title. In Neverseen, many human girls are ogling at Fitz, so he is alluring. Many other boys are jealous of Fitz because he gets all the girls as he is so good-looking. He is also described as looking like a "teen supermodel", along with Biana, Dex, and Keefe.

Abilities
Telepathy- Fitz is a talented Telepath. He is able to hear other's thoughts and successfully block anyone who tries to enter his mind, usually. Sophie is the only one so far to be able to enter Fitz's mind other than Quinlin. He was also able to transmit to Sophie when she almost faded in Keeper of the Lost Cities. In Exile, after Sophie was healed, Fitz was not able to transmit to her anymore, much to his disappointment. However, during Everblaze Sophie learns to trust Fitz enough to allow him into her mind. Fitz also can sense everyone but Sophie entering his mind.

Telekinesis - Fitz is noted to be excellent at Splotching, a tournament played at Foxfire. He has won every splotching match except the one in Keeper of the Lost Cities, which he lost to Sophie Foster. She won by unintentionally using a brain push against Fitz's core energy, which caused them to both fly back into the wall, leading to another visit to Elwin at the Healing Center. It was stated that Fitz hit the wall much harder than Sophie, which is why she won.

Biography
Fitz has one little sister and one older brother, Biana and Alvar. His best friend is Keefe Sencen.

In Keeper of the Lost Cities, Fitz is the one who find and takes Sophie to the Elvin world. Fitz was also the one Sophie called to when she and Dex were kidnapped by the Neverseen. With the encouragement of Keefe and Biana, Fitz was able to find Sophie and Dex by the Four Seasons Tree and stayed with Sophie there until Elwin came to stop her from fading away.

In Exile, Fitz accuses Sophie as being damaged and the reason why his father, Alden, ends up with a broken mind after taking Sophie with him to Exile to perform a memory break on Fintan. Fitz and Sophie's friendship breaks until Sophie comes back to retrieve Alden's mind after she has healed from her own problem. Before Sophie heals Alden, Fitz takes her aside and apologizes for his rude behavior to her. He explained that his anger was a way of coping with the grief of losing his father. Fitz also said that whether or not Sophie could heal Alden he would stop blaming Sophie for Alden's loss.

In Everblaze, Fitz and Sophie have telepathy lessons together and learn to trust each other in order to heal Fintan's broken mind. They learn to trust each other by sharing secrets about themselves so that Sophie would let Fitz into her impenetrable mind. One of the secrets Fitz shares with Sophie is Mr. Snuggles, a sparkly red dragon given to him by Elwin to help him cope with the grief of losing his father when Alden's mind was broken. Fitz is very patient through this process even though Sophie keep locking him out of her mind in instinctual self-protection. Together they develop code words to keep what they are doing during the mind-healing a secret from Fintan. They preform the healing but the whole is a disaster because of Fintan sparking Everblaze. Fitz saves Sophie from burning by yanking her away from Fintan; Sophie then teleports Fitz and Oralie away from the burning tower. Together Sophie and Fitz collect Quintessince, to create Frissyn, and stop the everblaze.

During Neverseen, Fitz joins the Black Swan along with Keefe, Dex, Biana, and Sophie (as well as his mother, Della, unbeknownst to him). There he and Sophie work on becoming cognates. They finally tried to go save Prentice in Exile. Fitz gets seriously injured in exile by being thrown back on arthropleura after throwing one of Dex's gadget in the hall to stop it from exploding from one of the counselor's lightning. Dex took him back to the Black Swan's hideout to get treated by Physic. Fitz took a week to heal by drinking "vile tea". When Keefe visited his room he found Fitz cuddling with Mr. Snuggles. They were then sent to Exillium. Fitz got off of the Arch of Dividing by doing what Sophie called "a gold medal worthy flip" then untying the knot and levitating to the ground. Fitz went with Sophie to save a gnome that was infected by the "plague". He along with Sophie tried to read King Dimitar's mind as cognates. He let Linh lean on him after she lifted the river to get into Ravagog. Fitz backed away from Alvar when he knew he was with the Neverseen. Fitz also cried when Keefe joined the Neverseen.

In the beginning of Lodestar Fitz gave Sophie Cognate rings, telling her his full name was Fitzroy Avery Vacker. Fitz said he didn't trust Keefe after he left to Neverseen. Fitz and Sophie went to try to read a few more things out of Prentice's mind. Fitz, Biana, Sophie, Dex, Linh, Tam and their bodyguards went to Keefe's room to see if there was anything related to the Neverseen, playing Boys vs. Girls to see who could find more things. The girls won and Fitz noted that he owes Sophie a favor. He said if Sophie doesn't use the favor in a month it becomes his. They found a leaping crystal in an envelope Keefe had not seen yet. It leaped them to Paris. Fitz, Biana, and Sophie had a sleepover at Dex's house. Fitz and Sophie visit Wylie to read his mind. Sophie and Fitz leap to Eternalia and ask Oralie to help them visit Gethen. After coming back, they found a note from Keefe on Sophie's bed. It had a leaping crystal in it and said "meet now". The crystal took they to a beach. Fitz didn't seem very happy seeing Keefe. Alden, Della, Edaline, and Grady eventually found them and Keefe leaped away. Alden said he cant leave the house until he finished his match packed but he finished right away the next day. After the summit, Sophie sent Fitz a message saying that she was okay. After the destruction, Fitz visited Sophie regularly. He may have possibly kissed Sophie but Keefe then interrupted. They went to Sophie's old house with Alden and only found Sophie's little sister Amy.

Fitz was the second youngest to get his nexus off and the youngest to naturally manifest an ability. He used to be the splotcher champion before Sophie. He has set many records.

Relationships (SPOILER ALERT! Contains spoilers from the latest books)
​Fitz first meets Sophie in the human world when he is looking for her. Sophie immediately takes notice of his attractiveness and begins to develop a crush on him. This is confirmed when she thinks "Fitz looked the best, but Fitz always looked the best". Sophie's first nexus is Fitz's old one that he doesn't need. The two become friends and frequently play Base Quest along with Biana and Keefe. When they go against each other in splotching it ends up badly, they both got slammed into walls because Sophie accidentally uses a brain push.
 * SOPHIE FOSTER (friend/possible love interest/cognate)

In Exile, Fitz gets mad at her because Alden's mind breaks, blaming her for it happening because she is "damaged." At the end, Fitz sincerely apologizes to her, Fitz regretting entirely what he did, and they become friends again.

In Everblaze, Sophie and Fitz find an extremely unique connection the two are put into telepathy lessons together to try to figure out why Fitz was able to pass Sophie's blocking. The two go through many trust exercises and Sophie chooses him to be her guide for Fintan's memory healing because of her unequivocal trust for him. Fitz saves Sophie from being killed by Fintan, by pulling her away. In the end of the book Fitz offers to cover for and share his cloak with Sophie.

In Neverseen, Fitz is shown to begin to have romantic feelings for Sophie after getting to know her and the two are trained as Cognates.

In Lodestar, Fitz has shown to have possible romantic feelings for Sophie such as holding her hand a lot, usually for things related to the Cognate training, as they have rings that snap their hands together, and almost kissing her, although Keefe interrupted. In one of the chapters, Fitz gets his Matchmaker packet and he says he would rather wait for a few more years, when she gets her first list. Fitz is also possibly starting to realize that Sophie may have a crush on him. He may possibly have a crush on her when he may have tried to kiss her in the end of "Lodestar" but was interrupted by Keefe, which seemed to make him annoyed. ​Alden is Fitz's father. They both have a very strong accent and look alike. When Alden's mind is broken in Exile, Fitz gets really angry. It seems Fitz is very close to his father and respects him, for he always knows that Sophie will call Alden if she is in trouble, and cares about him a lot even if it's through protectiveness caused anger. Fitz gets aggressive toward everyone except immediate family when Alden's mind breaks, and blames everyone for it. Eventually, Alden's mind is healed by Sophie, and Fitz stops acting aggressive. Alden cuts off Sophie, Dex, Keefe, Biana, and Fitz's registry pendants in Neverseen, and allows them to join the Black Swan. Alden seems to have an understanding of Fitz's need to help Sophie on her missions, and allows him to go with her willingly. ​Della is Fitz's mother. When Sophie and Fitz fall from a tree while playing Base Quest, she helps them treat their wounds and bruises. She cares deeply about Fitz as well as her other two children. After Sophie brings Fitz back from being lost, Della goes and hugs him tightly. Della also goes with Sophie, Fitz, Dex, Keefe and Biana to join the Black Swan and becomes a powerful asset to the Black Swan in Neverseen. Alvar is Fitz's older brother. He stays and helps out a lot after Alden's mind is broken.When Fitz apologizes to Sophie, Alvar shows up to tell them that the Council is ready for Sophie to heal Alden's mind. Alvar Vacker is also Fitz's role model! Though Alvar turns out to be a spy from the Neverseen, and tries to get them captured. Alvar is currently juggling three girlfriends. (Which Keefe very much admires.) ​Biana is Fitz's little sister. She cheers him on when he is splotching against Sophie (most likely because she didn't like Sophie in the first book). He is shown to be very protective over her. She is usually seen playing Base Quest with Sophie, Fitz, and Keefe. In Exile, they are talking to each other in the kitchen and Fitz volunteers to tell Biana the news about Alden's broken mind. The siblings tease each other and have a close family relationship. ​Keefe is Fitz's best friend. They hang out together all the time (at Everglen, Keefe never brings any friends home and Sophie was the only one). They often play Base Quest with Biana and Sophie and they play Bramble against each other (which Keefe always cheats at). He tells Fitz about what happened to Sophie when Fitz was angry at her about Alden's broken mind. After Keefe goes to the Neverseen, Fitz stops trusting him and their friendship turns problematic. Fitz was obviously angry at Keefe, especially when they met with Sophie, where he teased them. Fitz also started to dislike Keefe a bit more after interrupting a possible kiss between him and Sophie. Near the end of Lodestar, they both go to the Forbidden Cities, but they both did it just for Sophie. ​Dex didn't used to like Fitz, because he is very well aware that Sophie could possibly have feelings for Fitz. When they are first in a situation together, although they seem to have met before, Dex says he knows Fitz, but Fitz says he doesn't know Dex, making the conversation extremely awkward. He calls Dex "Deck", most likely by accident. When Sophie is mad because she found out Biana was forced to be her friend, Fitz sends Dex to go talk to her. Dex repeatedly calls Fitz "Wonderboy."in a jealous way. When Fitz and Sophie are splotching he cheers for Sophie. He is shown to be happy when Fitz got slammed into the wall much harder than Sophie. Dex also got upset when he found out she would be having telepathy training with Fitz, because he feels that Fitz is hogging Sophie. Finally, though, in Book 4, Dex blamed himself for Fitz's injury and they have a conversation and get over their prejudices, and become friends.
