Metroid Prime and Metroid Prime 2: Echoes

I recently bought Metroid Prime 3 for the Wii and was wondering is someone could fill in the back story from Metroid Prime and Metroid Prime 2. I haven't played them and don't plan on playing them. I got the gist of the story from Wikipedia and other sites, I've also played Metroid Zero Mission and Fusion, so I understand most of the story. I want a summary of the events that occurred in the first 2, NOT walkthroughs/opinions, reviews etc. So could someone please tell me the story?Thanks a lot!

well the saga of metroid is divided in two parts. the prime and the normal. the metroid fusion ocurs after the events of metroid 3(for super nintendo, ii think this is the best metroid ever),now the metroid zero mission is a ramake of the frist metroid(nes) but with more history about how sammmmus get the suit. finally the prime saga,well i think they just creat it to make the game a new gameplay beacuse the history dont have a good time line. actually metroid dont have a relly history is more like mission. i hope this will help you . ;D

Yeah I understand the timeline, but their is a story in 2 prime's. Something about the Tarvon IV and other things, that's what I want to know.

Hope this helps :)Prime 1:

Samus receives a distress signal in her new ship and travels to Tallon IV to stop the Space Pirates from exploiting a powerful radioactive substance known as Phazon. She discovers that the Chozo once settled on this planet, and their disappearance, as well as the emergence of Phazon, is due to a meteor impacting the planet decades ago. After ruining a Space Pirate mining operation and collecting the twelve Chozo Artifacts that allow access to the sealed impact crater, she confronts, and seemingly destroys, Metroid Prime, the apparent source of the planet's Phazon corruption.

Prime 2:

Samus is sent to investigate the planet Aether after a squad of GF Marines was lost there. Samus finds them all dead, killed by several creatures, mainly consisting of an evil race called the Ing. Upon meeting the only remaining member of Luminoth (the others were frozen in stasis chambers until the end of the game, where the last of the energy is replaced, and Dark Aether is destroyed), Samus learns Aether has been split into two dimensions by a meteor similar to the one that crashed on Tallon IV. Samus helps save Aether from the Ing, but encounters Metroid Prime once again, now called Dark Samus, a heavily mutated being who had copied Samus' genetic code and stolen her Phazon suit at the end of her Tallon IV adventure.

Spoiler (Prime 3) [highlight to read]:
Space Pirates shut down Galactic Federation computer systems and then engage in large scale combat in an attempt to further spread Phazon. Enormous Phazon-based seedships, known as Leviathans, impact planets and begin corrupting them with Phazon. Samus is charged with destroying the 'Phazon Seeds' and restoring functionality to the Federation's computer network. After purging three planets of Phazon (including the Space Pirate homeworld), the Federation locates the source of Phazon, planet Phaaze, which is made entirely of Phazon. As the Federation engages the Space Pirates in orbit, Samus enters the depths of the planet, and succeeds at finally destroying Dark Samus and Phazon once and for all.

Thanks, that helped a lot! I beat the game yesterday too!
