Fang is Jagged Stone's pet crocodile.
For a crocodile, Fang acts rather tame as he is never seen attacking people and seems fine with being a pet. As seen in "The Collector", where he seems to enjoyed his owner's performance. He also has some dog-like behaviors as he wags his tail and hangs his tongue out of his mouth, as seen in "Pixelator". Fang doesn't like being pestered and growls at Bob Roth.
- Fang is the first pet to have been introduced in the series.
- In "Pixelator", André Bourgeois assumes the name "Fang" applies to Penny Rolling.
- In "Guitar Villain", when an akuma flies into Le Grand Paris to corrupt Jagged Stone, Fang attempts to eat it.
- According to Penny Rolling in "Troublemaker", Fang hates flying on airplanes in the daytime.
- Fang's Dragon form reappears in the two-part special event "Heroes' Day".
- In the Serbian dub, his name is changed to "Zubonja" (Toothy).
