Olny Kaku, Califa and Bluneo are brainwashed
by Spandam. Olny Lucchi and Spandam are evil.
Fukurou, Kumadori and Jabura? I don't know but they were sent to kill 3 rebal leaders, I think Spandam is playing mind games on them.
Nero is just a saditic Vageta loser who wants to be the strongest
Kaku-seems to look remorse about betraying the Galley-La, he still showed respect for Iceburg, it seems he regrat kicking all his shipwrigth friends down when raiding the Galley-La HQ. He thinks he's doing the favor of destroying the ship against Usopp's protest.
Like GoAnderson said he still awknowledge his job, his duties and his skills. Many of his fan thinks he's evil but in reality he's really a good guy that don't know the true purpose of the mission. It's sad to see him getting his head beaten down by his fan for being "evil" when he still showed respect for Iceburg. The Going Marry is a different story, it's not evil to throw the chunks of wood into the sea, but he was olny paying his last respect a shipwrigth. It's not like if he going "HHAAHAHAGAGAHAHA!!! Prepare yourself pirate(Usopp) for I'm gunna stink ye ship!!!!!" but almost like " 'Sob' I'm gonna miss the Galley-La! 'Bohoho' " (Sinks the ship). The GM dispose is the good thing, this will finally have Usopp reunite with Luffy again. By the time he sees Spandam's real goal I'm sure he'll be peeved at him and figth him.
Califa- Still respect and loves Iceburg, and the town. She does not want to leave like she did. Like Kaku, she is just a brianwashed "pawn" of Spandam. Once she discovered Spandam's true perpose she will kick his ass.
Bluneo- He like GA said showed remorse about the Nico Robin thing. Even though he
may Shigined Usopp and kick Sanji down, he is not EVIL like Lucchi and Spandam but just one another brainwashed Spandam's "pawn"
That will eventully turn against Spandam
Nero- A newbie olny last for few chapters yet he does not know about the mission at all. He is like the Vegeta of One Piece expect he did not stay on the whole series like Vegeta. He always wanted to be strong for no good reason, he cares about his streigth reather then the mission. It seems Spandam just happened to find him in the streets of Mariejoa and recriut him as a CP9 agent without interviewing him.
Jabura/Fukurou/Kumdori- Not much known about them yet, I'll wait few more chapters to study their personally more. Yet I olny know they were sent to kill three rebel leaders but judging Spandam's attitude of their failure it seems Spandam is peeved by the WG's ordering him around and sent three agents to "shut them up".
Lucchi-Now he's the cold-hearted bastard. He really intent to kill Iceburg and Paulie. he is rude to Califa, Kaku and Blueno and these three are not happy to be around him. Yet he says "Don't kill any Straw-Hat crews" but he impaled Luffy, threw Zoro into the ocean, knocked Nami out of the burning buliding and buried Chopper in the rubble; what a hyrocrite. He had some shipwrigth to decoy their bodies thus fooling Tilestone. He seems to boss Kaku, Blueno and Califa around like his slaves. He is mean, heartless, selfish, spoiled, cold and bossy and he deserve a bloody pulp face by Luffy. I'll love to see Luffy turning him into a disgracful marsh of a bloody mass remains of him. Luffy, I'm counting on you to sent this asshole flying to the sun.
Spandam- He is the soul key of the Water 7, he is the REAL badass of Water 7 arc. Everthing that happened in Water 7 started by him (except the ship/Usopp/Luffy situation which is the subplot of of the Water 7 storyline) He is one crazy son-of-a-bitch with mentel problems of a mad sciantist who thinks he should use a badass weapeon that can destroy the world to end the age of piracy. Yes most pirates are bad but using a world-destruction weapeon to save to save by destorying is like cooking a weenier with a rocket engine. The five old shitheads were stupid enough to fall for Spandam's tricky metrod and yet they forgot that the ancient weapeon is too dangerous to handle. If the WG wants to get rid of pirates…THAT'S WHAT THE FUCK MARINES ARE FOR!!!!! ARE THESE GUY FUCKEN BRAINLESS!?!?!? Yet the WG should remamber they have Marines to do that job. I think the five old shithead have memory problems... I like to see Spandam go down the shithole before he gets the weapeon.
