Justin Russo

"I Promise"
 * ―Justin

Professor Justin Vincenzo Pepé Russo (David Henrie) is the eldest of the Russo kids and is a full wizard like his younger sister Alex. He's one of the most gifted wizarding students of recent times, creating his own spell, being able to use the Russo family wand with amazing success, and being well viewed by adults and professors, both mortal and magical. In the shows finale, Justin keeps his powers, replacing Professor Crumbs as the new Headmaster of Wiz Tech.

Even though Justin has many romantic relationship through the run of the show, his most significant relationship is the relationship with Juliet van Heusen which is ongoing.

History
Justin is one of the two family wizards out of the three Russo's, the other family wizard being Alex. He is the eldest out of the three Russo's. He is probably a favorite child, because he does well in school.

Personality
"One of the brightest students of recent times..."

—Professor Crumbs

Justin is one of the most intelligent and posses vast knowledge, both of magical things, such as spell craft and magical creatures, but also mathematics, history, robotic and geography. He's capable of built robots, water motors and mechanisms that simulate a flying carpet. His own knowledge makes him the chosen by his family to solve problems, like found excuses to hide magical affairs to protect magic from exposure.

Justin is labeled by his own family to be kind and generous but also has a vengeful and naive side. He strongly believes in aliens and that the language spoken by the Alien Language Club is actual alien and not make 'em up. He's also sometimes self-centered and likes to be the center of attention, being sometimes deceived when he's praised.

Abilities
Above average intelligence: In many episodes it's shown that Justin knows many things, his knowledge includes but isn't limited to, history, science, mathematics and general knowledge. In "Alex's Brother, Maximan" he builds a working robot out of house hold items, in "Franken Girl" he combines magic and science to build a Frankenstein like robot.

Hand-to-hand combat: As shown in "Wizards vs. Werewolves" he is quite skilled in hand-to-hand combat, being able to hold on his own against a werewolf for a short time, and seeing as werewolf's are stronger, faster and more agile than humans by an impressive margin, it is something to be impressed by. Although in a earlier story Alex laughed at the idea of him getting in a fight, so it's possible he only recently learned how to fight possibly, because of his monster catcher training. He also holds his own during the gang fight in "Western Show", further demonstrating his combat abilities.

Spells Expert: Justin is also a expert on spells, he seems to know on, for any occasion, IE, jumping off a cliff, sinking spells, he however isn't as good as his sister at make-ups. He also knows about spell locks.

Magic Expert: Justin knows a lot on magic of all kinds, IE, charms, potions, curses etc. Although magic doesn't come naturally to him he studies so much it makes up for it.

Marksmanship: As shown in "Wizard For A Day" Justin has crack shot.

Relationships
Family
 * Alex, Justin and Max: Trio of Russo

Alex Russo
The relationship between Alex and Justin is somewhat one of the closest relationships in the series. Alex and Justin are really close siblings, closer than the relationships with Max. Alex always confides in Justin, and when in a problem she turns to him, to help her undo a spell that went wrong. Justin has also shown to be caring and overprotective over Alex, such as in Wizards vs. Werewolves where he protects his sister from Mason.
 * Alex and Justin relationship

Kari Landsdorf
Justin had a crush on Kari in "The Supernatural" and took Alex's advice of using magic to get on the baseball team because she only dates baseball players.

Isabella
In "Beware Wolf" Justin goes on a date with a girl he meets online on WizFace. He starts falling for her but Alex tells him that Isabella is a werewolf and she tells him that she is.

Tutor
Tutor was Max's wizard tutor seen in "My Tutor, Tutor." She and Justin date for a bit up until she has to move on to her next student, in which he later finds out she's a elf, which is why he was so drawn to her. He found it odd that she was good friends with Alex.

London Tipton

When Bailey starts choking, London dumps Justin, still thinking he's a doctor, for not helping her. Justin hypothetically asks her if she would still like him if he was who he really is, which London thinks he is referring to Justin Russo, whom she believes just looks like "Doctor" and she decides to ask out Justin.

Juliet Van Heusen
In Wizards vs. Vampires On Waverly Place, when trying to get information about the Van Heusen's' new sandwich shop he meets Juliet whom he discovers is a vampire. They go on a date during Justin's twenty-five minute break just to see the trailers at the cinema and have a large popcorn. They fall in love but their parents don't accept them because of their rivalry in business. In the end the Russo's and Van Heusen's accept it reasonably so their children can be happy. Soon enough, Justin gets the job of monster hunting and embarks on a journey with Juliet to capture a mummy. They then get trapped and, to save Juliet from sunlight, he tells her to become a minion to escape while she leaves him behind. He promises he will find her. In "Wizards vs Werewolves" Justin tracks down Juliet, with the help of Mason, Alex's new werewolf boyfriend. After saving her, it is revealed that Mason and Juliet were a couple three hundred years ago. Mason declares his ongoing love for Juliet, causing Alex to break up with him. Later, Mason tries to convince Alex that he truly loves her, not Juliet, with the help of the love necklace which Alex threw away. Justin, Juliet, and Max pursue them and Justin refuses to let Mason near Alex which resulted in Mason fighting Justin to get Alex. Juliet attacks Mason to save Justin and in their fight, Juliet bites Mason and Mason scratches Juliet. This reveals that when a werewolf scratches a vampire, the vampire loses their vampire powers. Juliet reveals her real age of 2,193 years and becomes an old lady, telling Justin that even though he loves her they can't be together, and she crawls away into the forest. In "Moving On" Juliet observes as Justin finally forgets about her. In "Wizards vs. Everything" it's revealed that Gorog took Juliet back to her usual self and uses her to get Justin to work with him and not against him. After Justin, Alex, and Max destroy Gorog, Juliet and Justin reunite. In the finale Juliet attends the family wizard competition and cheers for Justin to win. Once he emerges first she tells him how proud she is of him.

Harper Finkle

Harper and Justin became close in "Justin's New Girlfriend" when Max thinks they are going out. They get stuck in a silent movie, which Alex hates, but in the end Harper and Justin decide to be friends. Harper is known to be very jealous and threaten any of Justin's girlfriends or any girl he likes, especially Juliet.

The two have since been good friends.

Rosie
In the episode "Everything's Rosie For Justin" Rosie enters Justin's delinquent class as they near a huge test that could get Justin and Alex back into the wizard competition. It is revealed that she is a terrible wizard and Alex gets Justin to kick her out of the class, despite the fact that Justin has a large crush on her and doesn't want to hurt her. Rosie comes back and gains Alex's sympathy; Alex does the copy-cat spell so that they can pass the test. It backfires when Alex gets the squirrel-frog on her robes and throws them off, causing Rosie to do the same and reveal she is an angel, not a wizard. She then apologizes to everyone, saying that she had only wished to meet Justin and see what he thought of her as a person. They begin a relationship, but instead of influencing him to do good she does the opposite and he becomes a horrible person. Alex finds out that she's an Angel of Darkness, not a Guardian Angel, and Rosie confirms it to Justin. Justin becomes an Angel of Darkness, breaking his wand, so he can be with Rosie but she wants him to leave before he's killed; he wants to stay for her so they can be together forever, like she had said.
