1st Round: First, unlock -all- other secret characters in the game. Then go to the Story Mode on highest difficulty and win every match without losing a partner and finishing off at least one of the other fighters with a move the drains a whole Super Bar. When you defeat the final boss Epsilon will appear (even if you have him in your team) before the post battle point wrap up and the following occurs:
Epsilon: "You're pretty good. This calls for a special surprise!" (Epsilon pulls something out of his armor but we can't see what it is) "I summon the ultimate cliche, hidden, nigh-unbeatable, final boss character!"
Epsilon throws the object into the air and suddenly it sparks with an intense light. The light glows and grows and and steadily form into a humanoid figure. It begin to fall to the ground, leaving streamers of incandescent energy that slowly peel from its body like silk from a cocoon. When he lands Omega Epsilon is fully formed. (Begin the "Dark Fact Theme")
Epsilon: "What? This isn't the one I wanted..."
Omega Epsilon: "She's here. I can follow her anywhere."
Epsilon: "Who the heck are you!?"
Omega Epsilon: (turns, noticing Epsilon for the first time) "You are... me? No..."
Epsilon: "Must be some avatar I never got around to fleshing out..."
Omega Epsilon: "You. You're the missing piece I've been looking for!" (suddenly Omega Epsilon draws his sword and runs Epsilon through, Epsilon gasps in pain) "With your soul, I will finally be complete!"
Epsilon: "No..."
Bright multicolored motes of light begin to o emerge from Epsilon and float into his Omega counterpart, at this point the winning team looks aghast and makes some reaction of dismay.
Omega Epsilon: (discards Epsilon's corpse) "Now, nothing can stop me." (he flexes his fingers) "I will remake existence in my image!"
At this point both of the players team members are on screen, both pose and shout out the equivalent of "Over our dead bodies!" with different variations for each.
Examples:
Epsilon: "Damn you! -I- was the destined to be the final villain of this drama!"
Dan: After Omega Epsilon kills him, Dan will run to GMCA Epsilon's side and try futilely to shake him awake. Realizing Epsilon is dead, Dan will lay his body down gently, and remain on his knees with a black expression on his face while his partner does their intro. He'll then stand slowly and silently take his stance, all the while glaring at Omega Epsilon with a dangerous look in his eyes. If his partner is Akane, he'll put his hand on her shoulder and say quietly: "Ikuze, Akane-san." before taking his stance.
Yun: In addition to the team members the KSP come on screen. Yun, I and Ch'oe are dumbstruck. Noe is celebrating Epsilon's demise.
Yun: "Chònggu, SHUT UP!"
Noe looks confused.
Noe: "But, Epsilon is dead. Isn't that what you wanted? Isn't that what you've been trying to do since we got here, take out Epsilon?"
Yun: (nods) "Yeah, I wanted to take him out. I wanted to beat him senseless, maybe even cripple him. But I never wanted to kill him. I don't care what he did in the past, he didn't deserve to die." (he motions for the KSP to leave the area) "This is gonna get ugly, guys. Go back to Korea."
Noe: "But..."
Yun: "This is gonna be messy. If I'm gonna die, I want you three [Note: he says "four" if Keori is his partner] to go on without me."
Noe nods and he and I turn to leave. Ch'oe puts his hand on Yun's shoulder.
Ch'oe: "Good luck, Ch'òlsu."
If Keori is Yun's partner she says something about being his partner and she's not going to abandon him even if he asks her to. He smiles and nods. She then does any intros she decides to add if any.
(V)ajin: (\/)ajin/Cyrus closes his eyes in thought and says "You remind me of someone." He then opens his eyes glares a Omega Epsilon and says "It doesn't matter though, because I will stop you."
Teotl: "So, what are you? Some kind of... astralvore?"
Omega Epsilon: "Label me if it makes you feel better."
Teotl: (to his wristcomm) "If my implant dies, nuke the joint. Everything you've got, Time On Target." (To OE) "Okay, little boy. Let's mamba."
Replica: (frowns) "Hmph. How... annoying."
Omega Epsilon: "Is that all you have to say?"
Replica: "Shush. You don't deserve my words."
Sean: The Cult of Guru Sean will be in the background as per one of his normal scenes as Omega Epsilon's entrance plays out.
Sean: (to the Cult) "...Go."
Kevin: "But, Guru Sean-"
Sean: (angrily) "GO!!! If there's anything left after this, you can come back should you still want to."
The Cult bows to him in unison, then vanishes in a flash of light. Sean turns back to Omega Epsilon.
Sean: (bitterly) "'Complete...' Could you really be any more lame of a DBZ ripoff? And you're just as meaningless, and empty, and awful as it was. I suppose stopping the universe from becoming like you is as good a thing to die for as any...." (He materializes the Silence Glaive.)
Omega Epsilon: (notices Glaive, smiles) "Oh, that thing again. When will they learn."
Reader: (looking slightly pale) "Bloody..." (starts to fumble in robes) "Maybe..."
Alyss: (looking even paler) "Won't work. It doesn't have a soul for a Morganti to eat. In fact... I think it's the other way around."
Reader: (waves, forming a portal a little behind them) "In which case... look after the cats and my place if-"
Alyss: "You think I'd just leave you?!"
Reader: "Alyss... you could die here. I mean, that... thing over there... It's not would, but SHOULD. If you stay..."
Alyss: "You're not going to do this alone, okay?" (in a much smaller voice) "And you're not going to leave me alone like this."
Reader: (collapses portal) "...thanks." (in very formal tones) "I, in turn, shall endeavor to prove myself worthy of such regard." (turning to face OE) "All right then, time to see if the previous practicals paid off..."
Kurt: (KM watches in shock as Omega Epsilon appears and casually kills Epsilon. When Omega Epsilon finishes making his speech, KM steps forward) "I have a problem with that."
(Feel free to come up with your own!)
At this point, if Akane is in the Team she steps forward.
Akane: "You bastard!" (an aura of power starts to form around her) "You ruined my life! I won't forgive you!"
Omega Epsilon: "So it -is- you. Haven't you learned you can't defeat me yet?"
Akane: "I don't care how powerful you are..." (clenches her fist and raises it up, suddenly her aura burst outs and creates a crater, rocks begin to float into the air around her) "Ryouga, Tenchi, Konatsu, Goku... my friends... my FAMILY! For them all... I will not lose this time!"
Omega Epsilon: "Heh. A nice speech. But I have no more need for you. This will be our final battle."
After Akane (or all the characters) have made their speeches Epsilon slashes with his sword in the air.
Omega Epsilon: "Enough words! You can not stop me, but you are welcome to try!" (he raises his sword) "Witness my true power. Omega Point!"
Suddenly the stage begins to tremble and shake. Then it seems to be pulled apart. It becomes clear that a massive black hole has suddenly sprung into existence nearby and is absorbing all reality around it. The players are left standing on a piece of floating rock, in the background the huge black hole pulses like a heart. Objects of all sizes, from people to galaxies, can be seen spiraling into oblivion behind them (the bigger they are, the slower they go). Omega Epsilon then smiles and drops into his Standard Form stance.
Omega Epsilon: "It's only a matter of time now."
(Begin "Termination" and the fight).
