Don Dogoier

"GokaiGreen!"

A man from a cautious sect that has an alarmist attitude, and always assumes the worst. He is a pacifist who causes trouble because he wants to avoid fighting. However, it is due to his quick thinking and rare brain power that compliments Marvelous' reckless attitude. Inventions from his calm judgment and clear brain often end up saving the team when they're in trouble. His nickname is Hakase (Professor/Doctor)

GokaiGreen
Like his predecessor ShinkenGreen, Don possesses the least amount of skill, as shown from his falling from tall buildings. In battle, however, he duel-wields the GokaiGuns, focusing his fire on a single enemy in turn without the acrobatic flourish of GokaiPink.
