Fang is usually based on a puma with the elements of an electric eel (as mentioned by Sevarius).
Fang made his first appearance in this episode, seen along with Claw and Maggie, being revealed by Dr. Anton Sevarius. He later escapes with the other mutants. While Fang spoke once in this episode, his name is not mentioned.
While trying to meet her brother Derek Maza, Elisa and Goliath are ambushed by Claw and Fang who are summoned by Talon to kill Goliath. He and the other mutants are seen having a conversation about the memory about their escape from the Xanatos Corporation.
He is also known for harassing Hudson who was chained up in the Clock Tower about Goliath being unable to return. As Broadway, Brooklyn, and Lexington are talking about Hudson trying to stay up, Fang and Claw began attacking Broadway and Lexington. He is also seen chasing Brooklyn who was trying to escape. Brooklyn was able to fight back and was soon chained up.
While in the lab of Sevarius, Fang grabbed him until he is told to release him. He feels the same way like Talon about his long past caring about the antidote by Sevarius.
He is known for harassing a helpless elderly citizen named Al and is soon confronted by Brooklyn in the Labyrinth. He is alerted by Talon about protecting instead of exploiting, and is soon harassing with Maggie about talking to himself.
Fang is also despicable for harassing some of the guards near the gun booth and is later confronting with Talon about being king and has soon kidnapped Maggie. He soon ends up in a breakdown after Maggie has escaped and soon starts harassing Talon after Maggie has escaped.
Maggie tries to rescue Derek, but is captured by Fang. Fang is soon arrested.
Fang gets imprisoned for a short while for his crimes as Demona is lying down in her bed unconscious. After he escapes, he gets chased by Talon for escaping and is shot down by him. He is later arrested after being shot down near the roller coaster.
The Lost, Estranged, LouseEdit
He remained prisoner since his arrest in "The Reckoning", alongside Thug. Sevarius ended up releasing him and then assisting him, then Fang and Sevarius ended up capturing many humans. Then later on, he ended up capturing Yama and Hunter in the sewers and delivered them back to Sevarius during New Year's Eve in order to make them partygoers. He tried to use the CV-1997 Carrier Virus, but is soon defeated the Redemption Squad.
Back then, Fang and the Squad had returned back to the Labyrinth, but Sevarius isn't there. There, he and the Squad found that Tasha (an armadillo mutant) was causing suicide. He was almost killed by Yama and Hunter while trying to crack some jokes and this retaliation caused Fang and Yama in poor condition.
- Although Fang was voiced by Jim Belushi, Jonathan Frakes gave him only one speaking line in his first appearance.
- His real name is Fred Sykes, which is named after the Disney villain Bill Sykes, a character from the animated film Oliver & Company.
