Just recently, more info regarding the individual members of the 35th Anniversary Super Sentai team, Kaizoku Sentai Goukaiger has just surfaced the seas of the world wide web along with the reason on why they ended up on Earth!
They are a team of pirates who came to our planet Earth after hearing the tale of the Uchuu SaiDai no Takara also known as The Greatest Treasure in the Whole Universe! In their searh of the treasure, they encountered the Space Empire Zangyaku and so, the battle between our space pirates and the space empire begins.
Even if they are a group of pirates, they are accordingly, not scoundrels, so Earthlings, Don't get in their way!
Here now are the character descriptions of the Goukaigers as seen in the movie pamphlet of Goseiger vs. Shinkenger: Epic on the Silver Screen.
Captain Marvelous/GoukaiRed - The Young Captain of the Pirate Squadron who is always wild and shining. Desires everything to be stimulating, and is always curious. Once he sets his aims on a target, he moves forward without flinching, no matter what. He is the type to poke his head in where it doesn't belong, and he often brandishes his crew of 4 with unreasonable orders.
Joe Gibken/GoukaiBlue - Member of the Pirate Squadron who has a calm deposition, a serious character and a man of few words. A compliment from this man is rare, a man with a serious personality who is hard on himself. Always training up his abilities with weapons, and never misses. Has known Marvelous the longest, and as such, he understands Marvelous the best out of the entire crew. He was originally an elite of Zangyaku but after coming into contact with Marvelous, he becomes one of the Pirate Squadron.
Luca Millefi/GoukaiYellow - "A woman who surpasses the men." Though one side of her character is very manly, her other side is sensual (can be translated as "having an interest in the opposite sex."). She is also an active woman who dislikes needing to have a reason to act. Excels in recon and exploration, and has a strong tenacity for treasure hunting, earning her respect from her peers. However, her need to get the treasure often makes her forget the mission is in front of her, be that when it comes to the enemies, or her friends.
Don Dockoiyer/GoukaiGreen (aka Hakase) - An alarmist from the School of Caution and always expects 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' wreckless attitude. Inventions from his calm judgement and clear brain often end up saving the team when they're in trouble. He is also, the team mechanic.
Aim de Famille/GoukaiPink - A former Princess of a certain planet who was picked up by Marvelous in space. Has "Geniality" and "Grace" that doesn't suit a pirate, making her quite different from her 4 shipmates. If a person is in distress, she can't help but want to help them. However, because she is always looking for someone to save, she can be a pain in the neck for her teammates. Also, she loves tea.
