Don Dogoier

"Gokai Green!"

Don Dogoier (ドン･ドッゴイヤー), better known in the crew as "Doctor" (博士) is Gokai Green (ゴーカイグリーン) of the Gokaigers.

Gokaiger
He's seemingly spineless attitude is actually hiding his true courage which he shows when his friends are in danger. Don ran a repair store in the middle of nowhere until he met Luka and recognized her from her wanted poster when the girl's crew needed repairs on the Gokai Galleon after a brush with the Zanyack. He boarded the Gokai Galleon on his own volition later to honor his promise of helping out with the repairs, claiming himself to be a refugee from a Zangyack-conquered world. Other than fixing the ship, he single-handedly cleaned the filthy living quarters and gave the crew a decent meal before getting on with the needed repairs. Don's skills in gadgetry, cleaning, and cooking impressed Marvelous immensely, leading Don being shanghaied into the crew while being nicknamed "Doc" (ハカセ Hakase?). During battle, due to having little to no martial prowess, Don relies heavily on stealth and trickery using the environment around him to improvise attacks. His clumsiness in battle would often end up looking like he is doing comedic slapstick.
