Why did CP9 get given animal fruits and an animal theme? What about the Admirals?

[Warmmedown]

Someone seeks them out for CP9. Was this Lucci or Spandam's choice? Or a group vote? Or is an order from the Gorosei or some other World Government employee?
I guess Admirals are given extremely powerful fruits? I guess they usually make a name for themselves in the marines first, before getting a fruit?

Probably an order from whoever Spandam's boss was.

The CP9 arc is pretty funny in retrospect. You have Robin who is basically the last living human who can decipher the poneglyphs, and instead of sending in the far superior CP0, you send in the weak CP9 for such an important mission.

Yeh, they spent ages trying to track her down too, I'm guessing, since she was undercover as Miss All Sunday. CP9 were ample strong enough initially even without DFs and did almost catch her successfully. The SHs got lucky with having the sea train and recruiting Franky. But if they knew Luffy was Garp's grandson, Dragon's son and that he had Nika Nika, they could've played it safer.

Tbf CP9 just happened to be in Water 7 though, as undercover shipwrights there to deal with the blueprints to Pluton/kill Cutty Flam. They just got lucky encountering Robin. So I guess that's the main reason. Aokiji could've also wanted to give Robin and Luffy a better chance of escaping, rather than getting CP0 involved.
