It also makes sense because in the original mythology, Vritra IS an Asura.
Then it starts entering Fridge Horror territory. Could it be that Vlitra used to be a Guardian General that used the Wrath mantra prior to Asura and lost himself to his wrath but never got out of it, and in the end becoming the Golden Spiders pawn?
Well, Vlitra is actually Gaia's Vengeance personified, and the Gohma were created by the Golden Spider in the first place. Nothing has ever stated what happened to the last possessor of the Wrath mantra. More than likely, that predecessor died in combat with the Gohma, as Kalrow is the oldest of the Seven Deities, and Augus, when unaffiliated with the Eight Guardian Generals, called them all weak. As far as I know, Asura has been the only known Demigod to take his powers to such a level.
When I was near the end of Asura's fight with Chakravartin, I was...mystified. All of a sudden, I was pressing Action Command buttons for Chakravartin, along with the buttons for Asura. It wasn't until about half a minute in that I realized...although I was pressing those buttons, I was not the one who was giving the commands. So I stopped...and the buttons kept on pressing themselves for Chakravartin. Then it hit me in a flash of brilliance: I was so consumed with trying to tear Chakravartin apart, that I forgot what he was, and what I was doing. I was fighting the Creator.
Who knew that the first boss fight in the game would foreshadow the last fight on the DLC? When Wyzen became Gongen Wyzen, he drew upon the Mantra Reactor, the Brahmastra's power source. During this stage of the battle, Gongen Wyzen calls Asura this: "The Destructor".
Why did Chakravartin lose to Asura when he is described as omnipotent? He is The Creator, he only sucks at destroying.
Speaking of Chakravartin, the self-styled "Spinner of All Mantra" and named by his debut episode as "the One Behind the Curtain". If you look closely, either in game or at his artwork, he has exactly 22 arms.The game, including all four main parts (and excluding the animated and Street Fighter DLC), has exactly 22 episodes. Chakravartin, the one behind the curtain, quite literally has a hand in everything that you do in this game
Why is Asura so much weaker than the Seven Deities until he gets really fucking pissed enough to trigger a burst and then knock them apart with a few punches? Because unlike everyone else in the Seven (save Augus, possibly) he never received a Mantra reactor when the Seven ascended. This isn't apparent until the DLC, where Yasha opens Asura's chest to reveal that he doesn't have a reactor, whereas Yasha does. That's why every battle Asura is involved in is an uphill struggle; until he gets angry enough that his Affinity for Wrath lets him draw on enough power to match his opponent, he's just not able to fight them evenly.
And the moment he does the first/only thing he does is kill The Creator. That is one hell of a power up.
Drawing on the above, how are Asura and Yasha able to defeat Deus despite his overwhelming power? Deus' Mantra Affinity is Pride. By constantly and continuously hitting him over and over, they keep wounding his pride and thus reducing how much Mantra he can pull. That's why Yasha has such a hard time against Deus in Episode 15.5, because Deus was still extremely powerful and thus Yasha's attacks did nothing, fueling his pride and making him even stronger.
When Asura completely loses it and becomes Wrath Asura, Yasha is able to get through to him, even though he has to beat the crap out of him to do it. Why? Because Yasha's Mantra affinity is Melancholy (read: Sadness). Rage is basically sadness at a much higher heat, so it makes sense that Yasha should be able to reach Asura in the state he's in; after all, they're both bitter over the state of the world and grieving for the same people.
Why do the Gohma have gold blood (and turn gold as their corpses disappear) despite their colors for everything else being black and red? Because they aren't actually the creations of Gaea — they're Chakravartin's, and his power is predominantly gold-colored when he uses it. As the Gohma die, the magic making them up returns to its original form.
Asura's personality becomes somewhat more balanced after having the Karma Fortress Mantra Reactor implanted because it exposes him to non-Wrath Mantra.
It seems funny to most people that as Asura is killing Kalrow he says "I tire of hearing about the world" when he is doing so much to protect it. That is until you realize he's not saying that he doesn't care about the world, but that he's tired of hearing the pathetic justifications that the demigods are using to explain away their cruelty to humanity.
When Asura and Yasha fight in Episode 21, Yasha is insanely powerful, despite ripping out his own Mantra Reactor and giving it to Asura. How did he become that powerful? His Mantra affinity is Melancholy. He's dying, and he knows it, so he's at his most melancholy in the entire game. It's no coincidence that when he's finally satisfied and smiling, that this is the moment he dies.
During a flashback, Asura is shown saying that he has no idea what to do when his daughter cries, except to punch the face of who or whatever is causing her to cry. At the end of the game, what is he doing? REPEATEDLY PUNCHING GOD IN THE FACE.
Fridge Sadness or Heartwarming, perhaps? During the opening of the final episode, Asura commandeers a Shinkoku battleship to soar into space to challenge Chakravartin. These battleships have been shown to require a sizable demigod crew, and Asura doesn't have his own unique craft or any known servants. In other words, it's implied that the leaderless remnants of the Shinkoku demigod armies are rallying behind Asura for one last defense of their beloved home - and consider Asura's battle strategy more or less entails catching Chakravartin's first attack head-on, they probably knew that it was a suicide mission, but did it anyways.
It seems strange that the world would be governed by eight mantras that are all largely negative emotions. Until you remember that in Hindu Mythology, the Asura race were the embodiment of all of negative emotions. It's the Devas, who are above the Asura, who get to embody positive emotions.
Asura and Augus both have blank white eyes. In Augus' case, it's because he's blind, unlike Asura, who can see perfectly. This doesn't make sense, until you realize that Asura, in a way, is also blind. To be precise, he's blinded by rage.
So, why do the humans not have subtitles to tell the player what they're saying? Because Asura doesn't know what they're saying. After 12,000 years, the language has changed to the point that he has no idea what they're saying, and neither does the player by extension.
According to some of Asura's lines to the Golden Spider this doesn't seem to be the first time he entered his Berserker form. Then what the hell drove him over the edge in the past?
If chapter 11.5 is any indication, that was the one other time he was driven over the edge with despair.
The Stinger at the end of the DLC hints at the return of Mantra. Does this mean Chakravartin was reborn as well?
Chakravartin says that everything that he has done (making the Gohma, giving the Gods the ideas for defeating it, etc.) was to choose his heir so that he can go on and find other worlds for his guidance. What if he has done it before, and Earth is merely the latest planet he's pulled his plan on?
We don't know that for sure, but we do hear him say that he has destroyed and reset the planet when the results don't satisfy him. Do we even want to imagine how many times he's done that? He's shown he'll do it as many times as he feels necessary and he has the patience to wait thousands of years. It's a terrifying thought.
Does this mean that there are others that are of similar power that decided to go on and find heirs so that they could continue the cycle?
