The Fight King's sword is the Fight King's main weapon as it appears in "Morituri Te Salutamus." It is very large and gold, glows with a yellow-green energy, and has two chips on either side of the blade. The Fight King's sword is his main (and presumably only) power source. It has the power to erect magical barriers, and binds the Gladiator Ghost to his arena. The sword was destroyed when the Fight King gave the sword to Finn, who promptly threw it to the ground. It shattered, causing the Fight King to shrivel up and die.
- The Runic code on Fight King's magic sword translates to: "To fight is to live."
- Even though it seems powerful, this sword is relatively easy to destroy.
