[Metroid] Samus Aran's a bounty hunter right? What notable bounties has she brought in?
gpt
An infant metroid after being hired to exterminate the entire species on its homeworld.  Though the infant wasn't a bounty, the Federation researchers were happy to have it.

The rest of the extermination went pretty well, considering, though.

Further back she was hired to deal with the known pirate base on Zebes, but that occurred before the planet's destruction (rumor has it Aran played a not-to-small part in that, though it was no bounty when she went back a second time).

The Federation basically seems to treat her as a one-woman HTR Unit, which is fair, as she's got enough Chozo in her to be faster and stronger than most others, and that's before you even bring her power suit into the equation.  She's not going to be hired to bring in some small-time hacker, or a small-time gang harassing trade on lesser-used routes.  She's earned enough respect that they bring her in for things that tend to have a major impact.
