Fang is one of main character in BoBoiBoy.
He makes his first appearance in the Extended Finale, he is seen at the Rintis Railway Station going out of the train when BoBoiBoy is about to enter the train and leave. In Episode 1 of Season 2, he appeared again in Rintis Island Primary School as a student, he also appeared in The Haunted House (Season 2, Episode 2). He is jealous of BoBoiBoy not only in his powers but also because of the following :
- While he's come to the class as a new student, Gopal said that BoBoiBoy is more handsome than him.
- In the first day of class, Teacher Papa Zola said that BoBoiBoy is smarter than him
- His classmates says that BoBoiBoy is more cute and more stylish than him.

In Season 3, Episode 23 he was helping out with the Earth Carnival by handing out pamphlets. He joined the others when they went to go see BoBoiBoy in the classroom but he suddenly left in a hurry when he received a message on his Power Band. Later that night, he is seen in the Haunted House bringing up a hologram of Ejo Jo's ship, apparently contacting the alien, and saying he had received the message and was now ready.
He makes his first appearance in the extended finale, but plays a more prominent role in the pilot episode of Season 2 as a new student at Rintis Island Primary School, where he is portrayed to have a cold demeanour as well as a pompous and arrogant attitude. He spoke very few words and he typically avoids speaking or socializing in school. However, beneath his seemingly calm exterior is a fiery temper, which is usually set off upon encountering someone whose popularity and talents rival those of his. He is unable to curb his rage when BoBoiBoy appears to be more popular and is declared to be academically superior to himself.
In Season 2, Episode 6, Fang's mean attitude towards BoBoiBoy and his friends began to lessen and by the end of Season 2, they have all become good friends. Fang’s most prominent flaw is his superficiality. He never misses a chance to boast about his abilities and popularity, and especially regards the latter with great value. However, he is shown to acknowledge his mistakes, as well as to redeem himself instead of running away. He resolves to rescue Ochobot in the end, obtaining his signature power in the process.
He also does seem to want to become friends with BoBoiBoy and the gang, hanging around them even when they were behaving hostilely towards him (upon suspecting him to have harmed Ochobot in some way).
The kind of power that Ochobot gave to Fang is Shadow Manipulation. The shadow caused a huge dragon that attacked Adu Du and Probe and the whole city. Fang can't stop it, so Ochobot is the only one who could. Fang loses his power when it's sundown or sunset, as it was revealed in Season 2, Episode 2. This is most likely because there is no or limited light source for him to make shadows. However, when he first received his power, he was able to conjure a Shadow Dragon during nighttime. Another time when he used his power during nighttime was during Season 3, Episode 16 when he conjured a Shadow Tiger, Shadow Eagle, Shadow Shield and Shadow Finger Prick.
- Shadow Tiger (Harimau Bayang) - used to scare and intimidate his enemy.
- Shadow Scratch (Cakaran Bayang) - used to make the Shadow tiger scratch his foe.
- Shadow Shield (Perisai Bayang) - used to protect himself or others.
- Shadow Shifter (Bentuk Bayang) - use to make a black trail that hit any foes that get in it's way.
- Shadow Attack (Serangan Bayang) - used to creating black mass out of shadows to blast his foes away.
- Shadow Hands (Jari Bayang) - used to trap his enemy.
- Shadow Cocoon (Kokun Bayang) - can be formed by combining the Shadow Hands together.
- Shadow Speed (Gerakan Bayang) - use to run fast by enhancing his legs' movements.
- Shadow Eagle (Elang Bayang)- used to construct an eagle out of shadow as means of transportation, used it to get away from the Crazy Cat.
- Shadow Rat (Tikus Bayang) - used against the crazy Cat.
- Shadow Dragon (Naga Bayang) - his first power, it was formed when Ochobot gave him his power, but Fang can't control it. In Episode 39, Fang used this to break P.E.T.A.I.. Whenever Fang used this, he always faints after he used it.
- Shadow Hallway (Lorong Bayang) - used to protect his classmates.
