Why the SA-X seems to assist Samus is unclear, but it is likely that the X saw two threats: one with only a few strands of Metroid DNA (Samus), and a full-blooded, incredibly powerful Metroid (the Omega Metroid). The SA-X then attacked the greater threat; if this is the case, then it probably intended to finish off Samus after the Omega Metroid was dealt with. It is possible, however, that Nintendo was recreating the ending of Super Metroid where the Metroid hatchling, after growing a relationship with Samus (its "adoptive mother"), sacrifices itself to save her from the final blow. The SA-X may have done the same thing. Less likely but still possible, after being defeated by Samus the SA-X grows to respect Samus as an admirable adversary and therefore protects her.
it is the speed run!!!!!!!!!!!!!!!!!!!!!!!! you get it when you kill serris in sector four. it is actualy called the speed booster and you ge it after killing the serris X in sector 4. look out for his charge.
Kill Ghor.
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.
he kills omega with the spirit bomb
You kill people
A-ha! Good question. Well, a Metroid is an alien (of course), which likes to latch onto peoples' faces and drain their life energy. You should search MetroidWiki, an then search in that website: Metroid Alien. a way to kill or stun them is to get into your morph ball when it attaches onto your face or use the ice beam.
Most likely.
Scan it, then shoot the weak spot.
Shoot all the tentacles off, then shoot the pupil over and over when it is floating.
go to the containment zone in the ice place, and kill the giant rock monster
yes he tries to kill all eggman robots
