History
Grinataur made his first appearance at the Sanzu River where Serrator told him about his mission. So Grinataur plan is that he'll fire his black sand at a couple of people making them be hungry and thirsty causing them to eat and drink until they explode and after that he left the ship and into human realm to cause misery.

Speaking of which Grinataur appeared in the human realm hidden himself in a bush as he open fired onto a couple of victims with his black sand. As this goes on his scheme hasn't been unnoticed when the Samurai Ranger shows up. So he brought out the Moogers to rangers occupied while he fires out more black sand at another unsuspecting resident. As the battle rages on Emily is now fighting Grinataur as he launches a couple of Exploding Peppers at her. Once Emily de-transformed he open fired on her, but Mia and Kevin sacrificed themselves as another victims of his eating scheme as well as Mike, Antonio and Jayden. After that Grinataur is out of ammunition and is nearly drying out so he retreats back to the Sanzu River to rehydrate himself.

Back at the Sanzu River he apologized his boss for his failed attempt on defeating the Rangers, but what he did to them caused to bring more misery in order to rise the Sanzu River into the Human Realm. So with that said Grinataur left the ship to continue his plans.

Back in the human realm Grinataur was seen battling Jayden as he used his club sword to send him further then tossed more of peppers at him, but they were blocked by the arrival of Emily. So he begins battling her as this goes on Emily's determination of not giving up makes her worthy of the Black Box where she'd destroyed him in Super Samurai Mode causing those that were hit by his sand not be hungry nor thirsty anymore.

He then resurrects himself as he becomes a Mega-Monster to battle the Samurai Gigazord. After that he was then destroyed by this finisher called Ultimate Samurai Slash.
