>If they were to use even more power than they did, they may possibly awaken the very catastrophe they sought to avoid within themselves
The Anti-Spirals are an advanced race with highly advanced technology, this technology grants them godlike power, which when used appears as red energy (not Spiral power). Through that technology they can manipulate the laws of physics and quantum mechanics, but they are not using Spiral power though.
>they might cause Gurren Lagann to progress to that state out of sheer necessity to overcome them.
My main statement was that the Anti-Spiral's lost due to PIS, The Anti-Spiral's fought Team Dai-Gurren on an equal footing, in the movie/s (which I know are not canon) it is even showed how when TTGL transformed into STTGL, Granzeboma transformed into Super Granzeboma, which to me still seems awfully like what would've occured, had TTGL done so in the original series.
Hypothetically speaking, if TTGL got stronger and stronger in order to defeat the Anti-Spiral, the Anti-Spiral could've done so as well in order to match them every time, but he could've also become 1000x bigger and stronger in order to create an attack 1000x stronger than the big bang as to disintegrate TTGL/STTGL.
>well, team dai-gurren managed to overcome the impossible before
The technology of the Anti-Spiral's is so advanced that they can also manipulate probability with/through it.
>Second, Gurren Lagann is shown on multiple occasions to have the power to break through dimensional walls and has the capability to attack every point in space and time at once with a missile barrage. If the Anti-Spirals fought them on those kinds of terms instead of remaining within a single pocket dimension, the results throughout the universe would be cataclysmic
The Anti-Spiral's fought them on the same plane ("You came all the way here to the space between the 10th dimension & 11th dimension so that we could finish you?") in a space that had, whilst different, still somewhat similar physical laws surrounding it. They appeared in a shape similar to them with the Granzeboma in order to truly fight them on an even playing field ("You are being oddly considerate, TOO considerate one may say. Why would you employ such elaborate, indirect methods? If you fought with all your might, exterminating us Spiral races, would be a trival matter''), as to induce ultimate and absolute despair upon them if they were to be defeated.
Other than that it is heavily implied that he was omnipresent in his universe/s.
The Anti-Spiral let's the Spiral races live, he just doesn't want them to advance too much because then they will use far too much of it (Kamina and the like are drunk on it), because through that all life will cease to exist, which he wants to perserve, because he cares, which clearly shows that he was far more intelligent and more thoughtful throughout the series up until the end, where Simon finally understood why he did what he did.
He/they could be considered as some abstract kind of Ubermensch.
The Anti-Spiral may or may not have survived the Spiral Nemesis, we don't know, but he cared more about the well being of the universe as a whole, like a guardian.
All in all, he should've won, and lost through literal PIS. I wish they would've just made him weaker as a whole so that his loss would've made sense, but through all the statements (and some feats), it's clear that he is far stronger, smarter and superior to any Spiral race.
