Yes, really. The Super Robot Wars
heroes are -much to their personal disgust- acquainted with time and interdimensional travel. Several characters from the original series have several versions of them (such like Kouji Kabuto
or Ryoma Nagare
), or have crossed into other dimensions (Show Zama
, again Ryoma Nagare
). Kouji Kabuto
himself has been stuck into a Groundhog Peggy Sue
situation in one of their series (and bits of official material hint the Gundam
universe itself and all Yoshiyuki Tomino
series form a gigantic Ground Hog Peggy Sue
So they accidentally landed in the post-Third Impact, original timeline we saw in the flashbacks episodes, they easily deduced what had happened (the cruxified MP Evas and Rei's giant head would be a deadly giveaway to Shinji, Asuka and Rei) and they decided fixing it. So Kouji, Tetsuya, Duke, the Getter team, Hiroshi, Akira, the Combattler team, the Voltes team, Kazuya, Sanshiro, the Zambot team, Banjo, Amuro, Char, Camille, Juudau, Hikaru, Noriko, Guy, the counterparts of Shinji, Asuka and Rei of the Super Robot Wars universe... tracked someone -Kaworu or whoever he answered to- powerful enough to correct things (there are several possible ways how they could have managed this: Shin Getter Robo is a hugely powerful sentient mecha is quite willing acting on its own (much like Mazinkaiser) and is powered by a sentient form of energy controls and manipulates evolution (the Getter rays), and how it was seen in Super Robot Wars Alpha, Instrumentality is NOT the direction the Getter rays want humanity going towards; Ideon and Raideen are sentient, divine mechas, and Rei is partially Lilith) and they kicked its butt to convince it into giving that dimension a new chance.
Then Kaworu agreed to send the Ikaris back in time (something he was going to do anyways), and he did so when Shinji and Asuka wished for a better life for their daughter. He never mentioned all of this to Shinji why he did wish not trouble him with tales of people from other world (and because he did not want to admit alternate Asuka had threatened him with grievous bodily harm if he ever approached Shinji).
Shinji and Asuka traveling back in time was the Plan B.
Whoever was behind the Angels attacks did not intend to exterminate the humankind or merging all human souls in a single being, but testing them (a trial SEELE caused and set off when they awoke Adam). When the Children failed on saving humankind, the plan changed to let Shinji and Asuka survive for a while on that lonely world to show them the consequences of their failure and what The End of the World as We Know It
really means, and then sending them back in time properly motivated to prevent Instrumentality. If they won this time around, they would have their daughter back, and a chance for a normal like
At some point of the crossover they will travel to the original and Rebuild universes. Butts will get much ass-kicking, Gendo
and even Yui
will get a reckoning, each Canon Shinji will get his red-haired girl
and each Canon Asuka will get her not-so-wimpy-now Shinji
Probably in Avalon
, since its ruler is such a fanboy of their parents. And they got along wonderfully.
