Male Porcupine is a marginally pudgy, light brown porcupine with dark brown eyes and a black nose. His inner ears are pink, and his quills are dark brown and white. His underbelly is grey. His eyes are also rimmed with this same color. Three strands of fur stick up on his forehead.
Male Porcupine is shown to be slightly grouchy, albeit a good sport. He seemingly allowed Bunga to bounce him on his head for a long time, only growing tired towards the end. He can be sarcastic, but does not wish harm on anyone.
After Bunga mistakenly believes that he is immune to everything (as opposed to snake bites as per Rafiki's words), he begins to bounce Male Porcupine on his head to show Kion how immune he is. After 99 bounces, Bunga drops him by accident. When Kion takes Fuli off to hunt with his family, Male Porcupine finally becomes annoyed, and when Bunga tries to pick him back up to continue, he sarcastically tells him to play in a volcano. However, the honey badger takes his words literally and runs off, with Male Porcupine trying to tell him that it was a bad idea, and that he was just kidding.
