I agree with poor quality profile of the characters in Gurren Laggan. The plan was that if I could, I would voluntarily help explain and provide evidence regarding the abilities that were there. For now I will explain here along with the evidence.
Power Null Justification.
At first they were a spirals people. However, they defected and called themselves the "Anti Spiral". They defected because of the reason that Spiral power can create Apocalypse (Spiral Nemesis) so that the
Anti Spirals lock and eliminate the evolution of their own Spiral power.
Spiral Power is the force which binds together lifeforms and the universe. By
negating their own spiral power, they need to live outside the universe which is why they created their own Universe on 10th - 11th D scale. That's why it is included in "Power Nullification" because Anti Spirals negate and eliminate the evolution of their own Spiral power.
Translate for
this:
"The universe was a closed universe. How many years were reassembled there? Of course, it doesn't make sense to count the time that has passed by in this space. Until known, there will be enemies who have been frozen. Time began to flow again with that information. The isolated universe, which was created solely for the purpose of eradicating the Spirals, are a major element that make up the universe."
It's a separate term that exists in the TTGL verse, where those with Spiral powers can create their own objects using their energy to "drill" as weapons. Example?
Simon.
Does this need to be questioned again? FTL is obvious because the size of the planes from Gurren Laggan and Anti Spiral have reached the
planetonics upto
galactic stage and also have warp transport that moves on a scale much faster than light. So it makes sense to include it. But you can also remove it since FTL is not an ability rather a speed case.
That's bit off and sounds iffy. I agree if you want to remove it. It sounds like Space-Time manip at glance.
Dimensional Travel Negation Justifications.
Here's the scan. Just like how @GreatIskandar1405 said, Anti Spiral capable to negating Gurren Laggan Ships device that allow them to Dimensional Travel.
Spatial Manipulation, Portal Creation, BFR Justification.
Anti Spiral is the universe itself. Because he is the universe itself, it has been said time and again that the
Anti Spiral has complete control over his universe. Including controlling aspects of it's dimensions. As you can see here,
Anti Spiral can even rip the space to explain about Spiral Power. He also
make a portal to attacks Earth once via Nia.
Durability Negation and Probability Manipulation Justifications.
Here's the scans with the explanations. We know that the Probability Fluctuations possessed by the Anti Spiral can also be included in the Space-Time Manipulation because that ability is one with the existence of the Anti Spiral itself which is also the universe. And in the
Durability Negation session there is an explanation of the Space-Time Durability Negation that can match this Anti Spiral ability; Characters who have the ability to manipulate space and time, can easily bypass physical durability of objects. Conventional durability does not matter, because the matter is secondary in relation to space and time. For example, it's as easy to distort a material object by distorting a portion of the space in which it is located. Or even send the object (or part of it) back or forward in time. The effect on the object will be the same, whether it's a sheet of titanium or a piece of cardboard.
Which is clearly still included in the Durability Negation.
Immortality Justifications.
Type 1: Anti Spiral's realm which is the Anti Spiral itself were
timeless. Translation: "The universe was a closed universe. How many years were reassembled there? Of course, it doesn't make sense to count the time that has passed by in this space. Until known, there will be enemies who have been frozen. Time began to flow again with that information. The isolated universe, which was created solely for the purpose of eradicating the Spirals, are a major element that make up the universe."
Type 3: Scaling to Nia whose capable to
regenerate after getting tortured by Anti Spiral itself.
Nia is a part of the Anti Spiral. Translations for that scans:
"Nia's scream is the only sound that echoed in the empty room. The Anti-spiral's homeworld. The space between the tenth and eleventh dimensions. An empty space-time on this planet, separated from both time and space. Nia, trapped there, is now about to be completely analyzed by the Anti-Spiral's original form. "No matter how much you examine my body, you will never be able to defeat them now. He will come, you can be sure of that." Nia said, desperately trying to regenerate.
Type 8: Anti Spiral is the universe itself. Which means, he'll still exist if you not kill him along with his universe. That's why after Simon success to kill Anti Spiral, the Anti Spiral's universe explode.
Does this need to be questioned again? Anti Spiral obviously has Invulnerability because he can negate any possible attack around him. So the attack will not be able to injure him. At the same time, Anti Spiral is also the universe itself. How do you attack the universe with normal physical strength? Of course you can't.
Abstract Existence (Type 1) Justifications.
Anti Spiral is the universe itself. He is pure abstract. The real entity of Anti Spiral onpar with Simon's Gurren Laggan who become the
embodiment of thought. Translations for that scans: "Simon's greatest enemy is this universe itself. The greatest, strongest, and most fearsome enemy that attempts to eradicate all creatures with Spiral power. Even before Simon and his comrades, numerous Spiral warriors have challenged the Anti-Spiral and been buried. Its form has no discernible substance, has capability to lightly transcend time and space, affects the multiple-dimensions. It is truly an entity that can be called "the universe" itself."
Mind Manipulation Justifications.
The Extradimensional Labyrinth
is a trap to confine victim's consciousness into infinite possibilities by materializing the multiverse,
generated by the divergence of the time axis at the moment of perception instant to instant and replacing it with infinite universes, a trap developed by the Anti-Spiral solely to prevent the Spiral Power from being used by the Spirals.
Large Size Justifications.
You should remove Large Size type 7 and 8 for Anti Spiral. They are indeed Large Size type 10. Anti Spiral is the embodiment of the Universe itself, which in his universe exist a 11 Dimensional Sub-Multiverses;
"Ninja Batman is a so-called "time thing" in which Batman is transported to the Warring States period. In Japanese anime, there's a restriction that if you change the past, the present will change, and I think people tend to be very cautious when it comes to time-altered anime. You don't worry about that kind of thing, and you go out on a limb.
Nakashima: That's because it's American comics. The world setting of the multiverse, or a universe full of universes, permeates the readership of American comics. And now, the time-modifying stuff is going to be the multiverse stuff, right? There's a whole universe of all kinds of possibilities, so no matter what you do, you're like, "Oh, that universe!" (laughs). The interpretation of the multiverse has advanced so rapidly in the last few decades that when we were children, it was only 4 dimensional, but now it is said to be 11 dimensional. Our job is to tell lies, so we take those theories and twist them into something interesting."
Gravity Manipulation and Radiation Manipulation Justifications.
It clears that Anti Spiral as the Universe itself capable to manipulate the Gravity and the cosmic radiation/only radiation in his Universe. He even created a
special region for this. (the scans exist in there so I don't need to bring or explain it again).
Aye. Anti Spiral is an amalgamation of Anti Spiral races that defect the Spiral Power into one. And he also has Mind Manipulation via Extradimensional/Multidimensional Laybrinth.
Time Manipulation Justifications.
The homeworld of the Anti-Spiral has been separated from the rest of the space-time continuum, with an independent flow of time, and is made of non-euclidean matter. So it would still count as Time Manipulation because they are manipulates the timeflow of their universe independently than the outside world. Translate for that scans:
"It is a strange room. It is not even a room. It is a place separated from continuous time and space. It is surrounded by walls, but I couldn't tell if it is matter, or if it is fixed time, or if it is something else entirely. It doesn't radiate anything. It doesn't reflect anything. It is not interfered with by any time in the universe. It is an independent time flowing only in this room."
Immeasurable Lifting Strenght, Higher Dimensional Manipulation, Higher Dimensional Existence, Justifications.
First, they are fighting in a universe that is in a
10-11D membrane so it's weight is immeasurable if you comparing it to our 3-4D universe. They are shown to be able to
lift objects as large as galaxies from the Universe which is said to be 10 - 11 D which if lifted will be considered as Immeasurable Lifting Strength. And Anti Spiral is the Universe itself of it (which the scans I have show you again and again).
All previous abillity that Anti Spiral have will get scaled to Simon too.
Simon is able to manipulate the Spiral's power into the Anti Spiral's Universe. He materialized the spiraling power into it. And, we know that the Anti Spiral Universe is Higher Dimensional (10 - 11D scale). Simon's Super Tenggen Toppa Gurren Lagann is one with the existence of the Anti Spiral Universe energy which is on a scale of 10-11D,
STTGL is the embodiment of the thought where the Super Spiral Universe is realized and this Super Spiral Universe exists on a par with the Anti Spiral Universe. Simon is STTGL itself.
I won't go to rest. Simon will have notable Abillities from Anti Spiral so that will explain the rest.
