Sergeant Tread

Sergeant Tread is a Nighlok monster appearing in the Power Rangers Samurai 1-hour special "Clash of the Red Rangers". He is voiced by Geff Dolan.

He has wheels for hands and is one of Master Xandred's best warriors. He was assigned by Master Xandred to help Professor Cog. After Professor Cog defeats both Red Rangers and sends the others into a vortex leading to Professor Cog's time, Sergeant Tread is told by Professor Cog that the Hypno-Bolts he casted onto the Red Rangers will kick in soon. Sergeant Tread is then told to give Master Xandred about the situation of the Professor Cog's Hypno-Bolts on the Red Rangers. When the Hypno-Bolts kick in, Sergeant Tread and Professor Cog watch Jayden and Scott duel each other. After the Hypno-Bolts were negated, Sergeant Tread leads the Moogers and Grinders into battle with him turning the Grinders into motorcycles. After taking down the Moogers and Grinders, Jayden and Scott end up fighting Sergeant Tread with Jayden using Scott's laser to shoot Sergeant Tread. The other Samurai Rangers return from Scott's time and managed to help destroy Sergeant Tread and Professor Cog.

Trivia

 * Sergeant Tread is the first and perhaps only Nighlok who does not become a Mega Monster after he is defeated. This is because they could not adapt the footage of the Mega Battle, because of the participating remaining RPM Rangers.
