Knuckles is number 8 in Pop! Games. He is from the Sonic The Hedgehog franchise.
Knuckles (or Knuckles the Echinda) is a anthropomorphic echidna and the guardian of the Master Emerald. He is one of the last remaining echidnas on Earth and the last of the Knuckles Clan. He possess superhuman strength and can dig and climb up walls with his spike-like knuckles on each hand. He can also glide through air. He is fully devoted to protecting the Master Emerald on Angel Island and is a independent, strong, and serious friend/rival of Sonic. He is yet easily fooled and short-temped and rarely cares about anything else that is not important as the Master Emerald. Knuckles also joins Sonic on his many adventures as he leaves his post sometimes to help him.
