Member of Team Sonic
Knuckles the Echidna is an anthropomorphic echidna and the current guardian of the Master Emerald, a powerful ancient relic which is his solemn duty to protect from anyone who wants to abuse it. He is also the sole remaining descendant of the Knuckles Clan and last of the echidnas on earth. His dominant traits are his superhuman strength, and the two spike-like knuckles on each of his hands, from which his name is derived from, which he can use to dig with and climb up walls. He can also trap the wind under his dreadlocks to glide through the air. A loner by nature, Knuckles is independent, headstrong and serious, yet gullible and short-tempered to a fault. He is fully devoted to his duty, spending most of his time on Angel Island protecting the Master Emerald, and rarely cares for anything that is not important. When his friends and others are in need of his help, however, Knuckles can always be relied on being willing to leave his post and prove himself a true and good-hearted hero. He is also one of Sonic the Hedgehog's oldest friends and rivals.
Knuckles was seen with the rest of Team Sonic (excluding Sonic) being held captive by Doctor Eggman. Whilst Eggman was distracted, he and the rest of Team Sonic were freed by Sonic. After Eggman's Keystone Device destabilized, he alongside Shadow, and Big were sucked into a rift. Knuckles can later be seen in the rift loop with the others (now alongside Omochao) after being rescued by Sonic, who now has the Device. After Sonic states Emeralds are missing, Big said he saw one, causing Knuckles to question where. His final appearance was once again in the rift loop where Tails said Eggman used the last Emerald to rebuild the Death Egg Zone.
- He is voiced by Travis Willingham, who voices him in the Sonic Boom animated series and all Sonic games released from 2010 until 2018.
