After the events of Wings of Liberty and after HotS - Plot advances!
At the end of HotS Kerrigan is reunited with Jim Raynor and then suddenly both runs into Tassadar!
Tassadar is like "I have come back from the dead to help".
Both Raynor and Kerrigan are glad.
Cue LotV - Tassadar, Raynor, and Kerrigan contacts Zeratul and help.
Tassadar came back strong, he is able to breath in space and fly/move faster than light. He can shoot energy beams of destruction able to destroy planets!
In fact Tassadar is apparently 50x stronger than Kerrigan! Yep that Kerrigan that can destroy BCs with her mind? Pfft Tassadar can do the same except destroy planets and breath in space. Tassadar said he trained and practice nearly non-stop under 10,000x gravity (gravity comparable to Earth) until he is this strong!
And they fight hybrids, try to reunite the Protoss... basically Tassadar is owning it up and doing all the work while Zeratul, Raynor, and Kerrigan all sit back and party. All is going well.
*Cue the gang of heroes collecting <insert plot relic>. Raynor orders his henchmen to collect the plot relic.
However a blast comes out of no where and kills all their henchmen.
It turns out the blast came from Tassadar!
*Raynor, Zeratul, Kerrigan all look in shock and all crap their pants (for those who have pants anyway)*.
Raynor: Tassadar Why? HOW COULD YOU KILL OUR HENCHMEN!
*Another Tassadar shows up (what there's two Tassadars now?*Tassadar (Actually "Fake Tassadar") comes and says "Wait! The blast wasn't from me. In fact I have something I need to tell you guys..."
Real Tassadar (who will now be referred to as Evil Tassadar) states "el oh el! Yes that "Tassadar" who accompanies you is a phony. I'm the real Tassadar and I am evil! Blarharharharhar. Blarharharara."
Fake Tassadar - Yes I am not Tassadar. I was a Protoss who was awed by Tassadar's accomplishments. He saved everyone! I felt Protoss... the Universe needed him again. So I became Tassadar! I performed surgery to look like him.. to sound like him.. to even think like him. In fact I am Tassadar... but I am really not. I am merely someone who tried to impersonate and mimic that heroic Tassadar who saved us all.
But I am surprised, how could this be. Tassadar what have you done!? To find out that someone who I looked up to be a ruthless murderer. WHY!!!!!!!!!!!
Evil Tassadar: Blarharharhar. I will explain:
They all find out that the Real Tassadar did not really sacrifice himself to destroy the Overmind. No he consumed the Overmind from the inside, absorbing its knowledge and therefore growing stronger! Everything was all a farce. He never wanted to save anyone. He wanted power. POWER!
In fact Tassadar (the real and evil one) is now 300x stronger than Kerrigan and can destroy planets easily.
Raynor: Oh noes what do we do? Run away? No we can't outrun Tassadar. Oh noes oh noes oh noes guys what do we do?
Fake Tassadar has a plan. He will sacrifice himself but he needs someone like say Zeratul, to help. Zeratul agrees with it and they both combine into a super mega Archon.
Fassatul (
Fake T
assadar + Zera
tul) proves to be a match for evil Tassadar.
However Evil Tassadar reveals he was only using 50% of his full power all along. He powers up and kills Fassatul.As Fassatul lay dying, Raynor picks him up in his arm and a scene similar to this plays out:Fassatul: Raynor... your son will bring the universe to ruin. Your son will save the universe!
*Fassatul dies*.
Raynor: No FASSATUL! This can't be happening! WHAT AM I FIGHTING FOR!
Legacy of The Void ends with Fake Tassadar and Zeratul dead. The dominion gone. Raynor and Kerrigan powerless against evil Tassadar or the Hybrids.
The end... or is it?
*Legacy of the Void ends here*.
*Cue fourth expansion pack "Rise of the Reapers".In the fourth expansion pack you play as Duran (a reaper) and Dark Voice (who is revealed also be a Reaper.) Both are just subordinates commanded by a the Reaper leader in another universe.
No not those Terran units but reapers are robots from another world or universe or something. Basically they're the masterminds behind the Hybrids all along (and not some rogue Xel'Naga but evil robots from another universe!).
You don't know much about the Reapers or where they come from but all you know is they have destroyed countless other universes before (in the SC1 multiverse, which acts more like planets rather than parallel dimensions) and they want this one too! Also they have masterminded the plan of creating hybrids and are using them plus a small amount of Reapers to take out this universe!
Goal of expansion pack
estroy everything. Take out Evil Tassadar. Play as Reaper/Hybrids*.At the end of the expansion you face off against Evil Tassadar. However your army of reapers and hybrids aren't enough against Evil Tassadar.
So Duran decides to call for backup as this is only "5% of the Reaper's full potential".
However one of the hybrids has actually hit an ancient temple which stands conspicuously in the middle of space!
Cue something similar to this happens (replace "Masari" with "Xel'Naga" ). Also cue Evil Tassadar and the Reaper/Hybrids crapping their pants:
That's right the Xel'Naga are back with a humongous ship (basically the size of a planet). Turns out the "few" Xel'Naga who survived were tired of being pacifists and decided to focus on weapons and other stuff to get revenge against the Overmind and all others who defied them in the past and who currently defy them still!
Seeing this, Evil Tassadar and the Reaper/Hybrid combo all focus their blasts on the Xel'Naga ship but absolutely nothing happens because the Xel'Naga are too badass.
*Rise of the Reapers story ends here.*Cue fifth expansion pack - "Xel'Naga strikes back" (also lacking "of" in the title because that's how the Xel'Naga roll).
In the fifth expansion you play as the Xel'Naga to face off against Evil Tassadar and the hybrids. Xel'Naga plays unique compared to the other three races:
1. None of their units/structures cost anything, It's all free. "It was said the Xel'Naga could create energy from nothing!".
2. They have heroes similar to WC3.
3. They're overpowered.
The final expansion pack ends with the remaining Xel'Naga facing off against Evil Tassadar. Tassadar powers up to his full power but dies. The Xel'Naga too have fallen.*Cue above MGS-like scene with Raynor (again). Raynor holds Tassadar in his arms.
Tassadar: I was jealous of you and Kerrigan and Fenix. Why was I not invited to your party that day!!!? Forgive me Raynor...
*Evil Tassadar dies*.Raynor: TASSADAR! No this can't be happening, not again. WHAT AM I FIGHTING FOR!!!
SC2 ends with a cliff hanger. The reapers/hybrids are still out there. Raynor, and Kerrigan are basically powerless to do anything.
The Xel'naga, Tassadar, Fake Tassadar, and Zeratul are all gone. What will become of them?
Actually I lied cue last (the 6th) expansion pack for SC2:
The "United Earth Directorate Strikes Back".
The UED returns with a vengeance with their high powered Tachyon lasers of doom. They'll show everyone how it's done.
