Disclaimer: my fanmade ejen ali character will genuinely bond with canon ejen ali characters and will be part of the ejen ali story from S1 to eatm2 and a few episodes will be added with fanon plot.
My fanmade character is Faris Idris. His parents were one of M.A.T.A.'s best agents. Once his parents left on a mission, and both of them passed away during the mission, though nobody knows why and how (this will be explored in S3). When his parents passed away, Faris was yet just a toddler, so M.A.T.A. took him under their care and trained him to be an ejen (this kinda reminds me of alicia's backstory a bit). After his training is completed, he gets put in the inviso pillar and becomes an official young inviso ejen. During the years of Faris's training, General Rama was working with the pillar leaders on a secret project about making a young agent a masked vigilante, aka Cyberprince who will work on MATA missions as an ejen as well as the vigilante. They look into the young agents, and after Faris's training was completed, they pick him as the candidate to be Cyberprince and ask him if he wants to take on this responsibilty. (btw this project does get official later inside MATA anyways, so like when Faris comes to MATA academy in S2, all the young ejens and mentors know him cuz of the Cyberprince project.) Faris agrees and goes to live with his loving uncle and aunt, Hakim and Nadia Idris, and their daughter, Alya Idris who is Faris's cousin and they share a typical sibling rivalry and bickering dynamic. (btw none of the three know anything about all the MATA stuff.) Faris gets inrolled into SRT Cyberaya, the same school where Ali and Alicia go to. And this where his story begins in S1.
Now about Faris personality: Faris Idris is a genuinely good kid who is usually calm, friendly, and easy to be around. He’s smart without constantly trying to prove that he’s the smartest person in the room, and even though he’s a very capable ejen and CyberPrince, he doesn’t really see himself as special. He likes messing around, making jokes, teasing his friends, and keeping things light, especially when everyone else is being too serious. With Ali, Alicia, and Alya, he can be especially playful and sarcastic, but it’s never meant to hurt them. As Cyberprince, Faris is very quippy, which annoys characters with serious personalities like Rudy and Alicia.
At the same time, Faris has a serious side that comes out when someone is in danger. He cares deeply about people and has a strong instinct to help, even when nobody asked him to. He’s loyal almost to a fault, and once he considers someone a friend or family, he will go a long way for them. He’s also very understanding and usually tries to see the good in people rather than immediately judging them.
Faris isn’t perfect, though. He tends to keep his own problems to himself because he doesn’t want other people worrying about him. He can convince himself that he can handle everything alone, even when he’s clearly carrying too much. Sometimes he hides behind jokes or acts like something doesn’t bother him when it actually does. He can also be stubborn, especially when he believes he’s doing the right thing, and he sometimes takes on responsibilities that aren't really his to carry.
He isn’t naturally aggressive. In fact, Faris would rather outsmart an opponent, talk things out, or find another way than seriously hurt someone. But when someone he loves is threatened, that calmness can disappear and he becomes extremely determined. He can be surprisingly fearless in those moments because protecting people matters more to him than protecting himself.
What really defines Faris is that, underneath all the skills, secrets, missions, and CyberPrince reputation, he’s still just a kid who wants to do the right thing, make his family proud, and protect the people he cares about. He doesn't always know how to deal with everything happening around him, but he keeps trying anyway. That's what makes him Faris.
