Synopsis for the TV Cartoon Stags' Challenge

Buguese has lost the first Oracle Key, but Mantid is unconcerned. They will find the other Keys and then come for Hunter's. Stag, the most powerful of Mantid's Big Four Generals, wishes to test himself against Hunter's "Electra-Twist" power. Hunter brags about his new-found power until Stags bursts through the castle and single-handedly overcomes Lumen's elite guards. Stags issues his challenge: If Hunter Steele does not face him in a duel, he will destroy Arachna Castle. Hunter is eager to accept, though no one has ever beaten Stags. An overconfident Hunter calls on the power of the Oracle Key, but nothing happens. If Hunter can't overcome his arrogance, Stags' victory will signal the final defeat of the Spider Riders!
