One of the most jaw-dropping action scenes in the Mike Young Masters of the Universe series occurs when the Snake Men overpower all of the Evil Warriors in the first "Rise Of The Snake Men" episodes. By far the most surprising moment is when Tri-Klops is struck by Kobra Khan's venom, partially destroying his rotating visor, and for the first time in any canon we see just how his visor works with his eyes!
