To defeat the Voltron Force, Zarkon tries to use the law to his advantage. It turns out there is a strict, ancient Arusian law that – when invoked – leads to gladiatorial combat between two sides. The Voltron Force must consent to the challenge or else. When the time comes, Lance and Lotor meet each other face-to-face in the ring. Needless to say, despite what prompted all of this, both intend to settle their own personal grudges. The raging fight, however, doesn't stop another devious Zarkon and Haggar plot from looming.
