first boss in metroid prime is parasite queen
As it is the first area in the game, the path is very linear. Simply get in, beat the boss, and get out.
yes
the final boss in metroid prime is (kinda obvious) metroid prime. BUT! once you kill metroid prime, you have to fight his soul. I believe the only way to harm metroid primes soul is with the phazon beam. He is very hard to beat if you're not an experienced player.
phantoon
shoot at the blue spots then shoot the core at the top of it / just shoot kandem until his dead
The Omega Metroid.
Dunno. It's a giant alien ghost thing...... maybe it just likes messing with ships?

You get an octolith each time you beat a boss however, If one of the hunters kill you they will take one of your acquired octoliths and you will have to get it back.
You get it after defeating the first boss before destroying the first leviathon seed on the first planet.
I am not spoiling the story but I will say this: when you beat the last sequential boss you can return to the bottle ship for 100 percent completion. When you return you can go under characters and see an extended bio for the marines.
