Athena sounds like a good name.
And Harry should only be injured if the female clones are going to nurse him back to health. Including sponge bathing him. Hello Nurse!
As for the Harem it should be three to four galactic girls. As for Earth girls it depends on how much time will have past while he has been gone.
By the way with Kamino being an ocean world do they use submarines, or for that matter water ships. I know they hae those cool cities up on stilts but with their tech couldn't they build underwater.
Looking forward to Harry and Legions moving out after the civil war is over. Maybe carving out a pocket empire. Should be interesting to see hwo things are when Phantom Menace starts.

Right now, I don't know how many romances he should get. As for info about Kamino, here is a small peace of it's history:
it used to be a frozen world, but the ice melted and submerged all cities they have at the time including Derem City(their former capital). They genetically change themselves to get gills along with their nose/lungs to breath. So they are adept swimmers and don't use submarines except for cloning some of those flying creature from Naboo (also genetically altered) to be used as transportation in the air and under the sea.
