He might also develop his magical abilities further as he would be exposed to new spells and techniques used by the Order members.
His character would likely become more empathetic. Being around the members of the Order, who fight for good, would expose him to different values. He might start to question the beliefs he grew up with as a Malfoy.
If Draco joins the Order, his character could experience a huge shift. He'd have to confront his family's beliefs. He might start to see the value in the Order's cause, like fighting against Voldemort's pure - blood supremacy. This could lead to him using his Slytherin cunning in new ways, perhaps by infiltrating Death Eater meetings and passing on information. His relationships with other Order members would be complex. Harry might be initially suspicious but could come to trust him over time. Draco would also have to deal with the internal conflict of betraying his family's long - held values.
When Draco joins the Order in the fanfiction, his character development is complex. He begins to question his old beliefs that were instilled in him by his family.

She challenges him intellectually and morally, which helps him to evolve into a more ethical and caring wizard.

Well, he would probably become more brave and selfless over time. In Gryffindor, the values of courage are highly emphasized. Draco, being in that house, would be constantly surrounded by those who act on their instincts to do what's right. He might start to question his previous Slytherin - like behaviors such as being so focused on pure - blood supremacy. His relationships would also change drastically. Instead of being friends with Crabbe and Goyle, he could form bonds with Gryffindors like Harry, Ron and Hermione, albeit with a lot of initial friction due to their past differences. This new environment would force him to adapt and grow in ways that are completely different from what we saw in the original series where he was a Slytherin.
If Naruto gets the Rinnegan and joins Akatsuki, his character would develop in a very complex way. His values would be put to the test. He's used to the Konoha way of life and values like friendship and protecting the village. In Akatsuki, he'd be exposed to a different set of values. His character could become more cynical as he sees the darker side of the ninja world up close. But at the same time, his inner goodness could also try to influence Akatsuki members. His development would also be affected by his new powers. The Rinnegan could make him more self - reliant as he discovers new abilities, but it could also isolate him as others might fear his power. He'd be constantly battling between his old self and the new self influenced by Akatsuki and the Rinnegan.

Through their play and interactions, he starts to trust the puppy completely. This trust could then lead him to be more trusting of others in general. He might also start to question some of the more cruel aspects of the Slytherin values he has been taught as he compares them to the innocent and loving nature of the puppy.
Her character could develop a darker side. Being around the Akatsuki, who are often associated with more morally ambiguous actions, might make her question her previous beliefs. She could become more ruthless in combat and decision - making.
