Fang was born and raised on an undentified planet under two loving parents and an older brother, named Kaizo. When he became of age, Fang started training under his own brother and joined his brother's team.
Sometime before the start of the series, Fang had begun studying Earth Life, as he was about to embark on a mission to infiltrate and spy on particular inhabitants.
Fang made his official debut in Season 2, Episode 1, where he appeared again in Rintis Island Primary School as one of the students. During this time as a student, Fang began to loathe BoBoiBoy, even though the two never fomrally met. Fang had been constantly compared to BoBoiBoy by classmates and teacher. As a result, Fang gained a bitter friendship with BoBoiBoy.
Fang later appeared in The Haunted House (Season 2, Episode 2), where he attacks both BoBoiBoy and Adu Du's respective groups. He expresses his jealously and resentment towards BoBoiBoy, telling him that it was his fault that he was unable to become popular.
In Season 2, Episode 4, he and BoBoiBoy are challenged by Teacher Papa Zola to play a game of football. Fang teamed up with Adu Du and Probe but ultimate lost to BoBoiBoy's Team. He, along with BoBoiBoy and Gopal, was shrunk by Probe's Shrinking Pistol (Season 2, Episode 5).
Although Fang was jealous of BoBoiBoy, he still tried to remain somewhat civil and friendly with 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.
In the final episodes of Season 3, Fang was revealed never to have been human at all, but an alien. He had been tasked by Captain Kaizo, The Legendary Space Rebel, under orders to find and retrieve the power bands on Earth, which at this time were under BoBoiBoy's Gang's posession with all force necessary. Although Fang was relunctant to attack his own friends, Fang eventually carried out the orders and managed to take the power bands, along with his own, to Captain Kaizo.
Conflicted on where he stood, Fang contemplated where he actually stood morally. He eventually decided to betray his brother and captain in favor of his friends, using his revealed intangibility powers to steal back the Power Bands. He had planned to give the power bands back in secret, but Kaizo revealed that he was aware of Fang's betrayal all along.
Subtly petrubed by Fang's betrayal, Kaizo offerred another chance to BoBoiBoy, as well as Fang, to maintain posession of the Power Bands under one condition: that they had to defeat him and Lahap. They accepted and Fang teamed up with BoBoiBoy to battle his own brother. Although it had been a difficult battle, despite the numbers being in their favor, the eventually managed to 'defeat' Kaizo. Kaizo eventually revealed his goal of finding the rightful owners of the power bands and acknowledged Fang and his friends as the rightful owners of the power bands. As they were about to leave, Kaizo asked Fang if he would go with him or not. Ultimately, Fang decided to stay on Earth with his friends. He also finally revealed that Kaizo was actually his older brother all along, much to his friend's irritation.
Sometime before the start of Galaxy, Fang apparently left BoBoiBoy's Gang and went back into space, presumably to continue his training under his brother, Kaizo. He had also joined the organization TAPOPS during this time, as well as coming to command of his own team, along two other members named Sai and Shielda.
Fang finally makes his debut in Episode 6, where he was apparently en route of solo flight training. He gets a SOS signal from the TAPOPS spaceship and arrives to help them fend off the mosquitoes. However, because of the mushroom-like helmet he was wearing, he is ridiculed by his friends, irritating him. Fang and BoBoiBoy manage to drive off the mosquitoes for good and he begins towing the spaceship towards the TAPOPS HQ.
Fang is a young humanoid alien with raven hair in a messy sort of style. He has noticeable similar features to his older brother, Captain Kaizo, both having the same hair color and eye color (In Galaxy). He greatly resembles a regular human being, instead of the kind of typical alien.
In Season 2, wear a magenta and dark blue jacket, with grey sleeveless shirt underneath his jacket, tricolor belt and dark blue pants. He also wears magenta-white shoes and pair of purple fingerless glove. Fang always shown with a full-frame purple glasses which later revealed be his Alien-tech mask. While in school, he wears a regular school uniform but has his jacket tied around his waist. He seems to have gotten a new pair of glasses in Season 3.
Three years older, Fang has grown much taller than he was before, as well as looking much more well built. He wears a long sleeveless purple jacket with a gray sleeveless turtleneck undershirt with a gray belt around his chest and waist. His pants are gray and he dons dark purple boots. On his hands, he wears fingerless gloves and a white and purple gauntlet around his right arm. His glasses are now red with light blue lens.
Fang first presented himself as a cold and unfriendly demeanor, much like his much colder brother, Kaizo. He displayed a pompous and arrogant attitude, as well as a strong resentment towards BoBoiBoy. Although he seems to be a relatively calm person, under this calm exterior is a fiery temper, which is can be set off at the drop of the hat, mostly towards BoBoiBoy. Eventually, after spending time with BoBoiBoy, most of the resentment faded away by the end of Season 2. One of Fang's ultimate goals in life is to 'popular' even when he was a spy on Earth, which might be a side effect to having a super popular older brother.
Despite being arrogant sometimes, Fang is one to acknowledge and admit his own mistakes and shows remorse when he does things wrong. Fang began hold his friendship to one even greater than his own brother. He betrayed and defied Kaizo in favor of his friends in Season 3. Despite all his bad points, Fang seems to want to be a good person, as a representation of all alien-kind.
In BoBoiBoy Galaxy, Fang had reasonably matured. He no longer carried his rivalry, jealousy, or his resentment for BoBoiBoy. He matured as a leader, as he had been tasked as captain of organized teams as well as the leader of his own team. Fang had also grown quite trendy, as he had worn a questionably fashionable mushroom helmet because it was a new fashion trend.

The kind of power that Ochobot gave to Fang is Shadow Manipulation. When Fang first received his power, he involuntarily conjured a huge Shadow Dragon that attacked Adu Du and Probe and nearly reached the city. Fang couldn't stop it, so Ochobot was the only one who could. After Ochobot stopped Fang's Shadow Dragon, he and Fang passed out from exertion, both apparently gaining some amnesia and losing their memories from that night. These memories resurfaced during the events of Season 2, Episode 8.
All of Fang's animal forms have glowing red eyes that appear to be on fire. 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.
In Season 3, Episode 24, it is revealed that he has unlocked two new forms: Shadow Koala and Shadow Bear. This gives him a total of 16 shadow forms. He also revealed that he is actually an alien and has the ability to become intangible, like a ghost, thanks to his glasses (perforation power). However, Fang's ability when using his powers seems to have a limitation. He is only capable of using one type of power at a time, be it his Shadow Manipulation power or his Perforation Power.

Kaizo continues to call him this, mostly probably out of affection.
