Robtish is a Nighlok swordsman with 2 squinted eyes and red skin, wears a helmet with spikes, and has a fierce grin with fangs and speaks with a Scottish accent. He wields a sword in battle and can unleash a sonic shock wave that is followed up by a Double Slash technique. Robtish is sent to kill Jayden and first appeared in the form of a swordsman. The other four Rangers had to defend Jayden and ended up injured in the process. Deker later interfers with the fight, and the fight becomes a duel between Deker, Robtish, and Jayden. Robtish ends up retreating after drying out. In "Jayden's Challenge," Robtish is sent back to the city to attack Jayden again. Robtish ends up leading the Moogers in attacking the park in Harper Village. Jayden ends up fighting Robtish and Moogers until the others arrive. The Rangers transform, defeats the Moogers, and ends up fighting Robtish. After the Rangers blocked Robtish's attacks, Robtish is defeated by the 5-Disk Tiger Cannon. Robtish grows to giant size and the Rangers summon the Samurai Megazord. Robtish unleashes flying Moogers who attack the Samurai Megazord. The Samurai Battlewing is formed and combines with the Samurai Megazord which forms the Battlewing Megazord and destroys the flying Moogers. The Battlewing Megazord then destroys Robtish with its Flying Slash finisher. In "Party Monsters," Robtish appears at a Halloween Party at a club in the Nighlok Heaven and recaps his battles with the Rangers to the other Nighloks.
