Personolaty
Alex is very smart, using her intelligence to get whatever she wants. She's very manipulative, using everyone's weaknesses to her advantage (like exploiting her father's love for food so he allow her to go to SS Tipton marine school). Actually, one of her flaws is her own reliance on magic and her laziness, which often results in magical troubles, as well her lack of disregard for rules. She despises Justin "nerdiness", though she's jealous on how smart, good and generous Justin is. However she always goes to Justin first to solve her magical mistakes. She also often make pranks at Justin and even Max. As the series evolved, however, Alex shown a softer side, and proved to not only be capable of being a "nerd", but also a good person, choosing to do good when the whole world was covered in darkness, and refusing to leave Earth when it's doomed to destruction from a meteorite crashing down on Earth.

After a heated argument with Theresa, Alex, in a fit of rage, wishes that her parents had never met. Justin and Alex set off to find the Stone of Dreams, guided by Archie. Along the way, Justin and Alex face many obstacles such as getting across a wide canyon, escaping death from quicksand, and getting across a narrow ledge. Jerry mentions that if one of the kids was a full wizard, they might be able to cast a spell to reverse it. While preparing to begin the full-wizard contest, Max finally loses all memory of who he is and gets sucked into the vortex of non-existence. Realizing they must work quickly, Alex and Justin are transported to an ancient battlefield, where the contest will be held. Alex narrowly wins.

Meanwhile Theresa is back with the Dream Stone. Jerry tells Alex she can wish for her brothers to reappear and still keep her full wizard powers. However, Alex wishes that everything go back to the way it was before, and time rewinds back to the beginning of the argument between Alex and Theresa that started all the trouble, which is quickly stopped when Alex apologizes and accepts her punishments with grace.

Alex had a crush on Riley in the episode "I Almost Drowned in a RileyChocolate Fountain" where Alex had to pass Spanish to go on a "not-so-date" with Riley and 13 other people. They talked about his car, and Riley suggested to Alex that he would get a keychain with her name on it. He also appeared in "Alex's Spring Fling", where, apparently, they are dating. He also appears in an episode where Alex convinces Riley that she's his good luck charm for the baseball game, as the team would only win when she was there.

Dean Moriarty
See:

He is Alex's boyfri end in the second season. He makes temporary tattoos in the boys bathroom and is interested in cars. In episode "Racing", he charmed Alex's parents with his car skills. Harper and Justin aren't too fond of him and Jerry seems the same way later on. He can never remember Harper's name. In episode "Alex's Brother, Maximan" it was shown he likes roller skating and playing with the claw game and winning stuffed animals.

Mason Greyback
see: http://waverlyplacewizards.wikia.com/wiki/Mason-Alex_Relationship

Mason is a transfer student from England, perfect to Alex in every way apart from his artistic vision. First appearing in "Alex Charms a Boy", Alex puts a spell on him to make him obsessed with painting her, though at the end the spell was lifted. In "Wizards vs. Werewolves", it is revealed that Mason is a werewolf, and he tells her that the necklace he gave her only glows when the wearer is in love with the person who put it on them. Mason helps Justin track down Juliet and rescue her from the mummy. In the process, Alex and Justin find out that Mason and Juliet had once dated 300 years ago. He then impulsively shouts out that he loves her, leaving Alex completely heartbroken. She throws the necklace and flashes out. Mason convinces Alex to come back to Transylvania with him to find the necklace and prove that he really does love her. She is finally convinced and they go back. Justin, Juliet and Max come looking for her, and Mason and Justin get into a fight. Juliet steps in to fight for Justin. As resulting of scratching and biting each other, Mason turns to a wolf and Juliet an old hag. Just in time, Alex finds the necklace, puts it on Mason, and it glows, proving that he loves her, but it's too late. Mason returns in "Wizards Unleashed", when the Russo siblings save him from country wizards, and manage to turn him human, but only after he has been stuck in a half-werewolf/half-human state. Mason and Alex also break up in the episode "Alex Gives Up" after Chancellor Tootietooie reveals that it is forbidden for a magical creature to date a non-magical human. Since Alex had quit the wizard competition, they would not be allowed to be together. Instead, they become friends. Mason remained a recurring character in many adventures with Alex. However, in "Wizard of the Year", Alex breaks up with him, because he didn't believe her she denies a gossip show rumor that Chase (first appearance in "Beast Tamer") and Alex were a couple. Mason stormed out the Wizard door in the lair. Alex waited for Mason to meet her for the Banquet, but he didn't come. When Mason lately came to the Banquet in honor of Alex winning Wizard of the Year, Mason sees Alex laughing with Chase. Mason turns into a Werewolf and asks Alex who she wants to be with. She chooses no-one and breaks up with him. In part 3 of "Wizards of Apartment 13B" they get back together.
