ExE is Higher dimension ( twit by author)

I see no valid proof about that unless you bring evidence

 

[Humanitus_Primevilus888]

This is not true

So you’re saying that Low 4-C x 4 = 2-C? Cuz if it is then that’s called shit ass scaling

And the fact that she lost a large “portion” of her “infinite”power she became “finite” which is her low 4-C self like since when a character who just lost a finite portion of their infinite power turn someone into a finite being like isn’t it infinity - finite = infinity?

"Ophis is not at 50% of her power; she has lost her infinite power and become finite. This is due to the Dragon Slayer's poison. Currently, her rating is around Low 4-C. However, based on Ddraig's statement about world destruction, I believe her actual rating is Low 2-C, as Ddraig's statement likely refers to destroying an entire world, not just a planet."

This is just pure assumption like how can Ophis, who’s is like 3-4 times stronger than heavenly dragon be low 2-C so base on calculations, a heavenly dragon is High 3-B and what’s funny is that when it took multiple( at least 10 to 14) 4-C to 4-A beings to take down 2 heavenly dragon and the fact is that 14 solar system is only equivalent to like 1/10,000,000 of a average galaxy(3-C).

Even If its cause by dragon slayers poison that absorbs infinite-1 of Ophis power, she will still have infinite power nevertheless. Not to Mention it impossible to for a finite character to get reduced into a finite being by a power created by a finite being in a first place

 

[Dark_Soul20189]

Question is, what does it have to do with canon DxD? Max they can possibly scale to is the dimensional gap, which has nothing to do with the other worlds. Every world has its own dimensional gap.

He is basically saying, "Since the game is primarily based on the anime/LN, so the information there can be used for the games, that must mean that the games are canon to the "canon story" LN and anime."

See the issue with this kinda thought?

You miss understand this part I am not saying ophis is low 2-C in his prime but the two heavenly Dragon are low 2-C before their death

Since weekend ophis claim that she is Still twice strong as two heavenly Dragons she get low 2-C

and what’s funny is that when it took multiple( at least 10 to 14) 4-C to 4-A beings to take down 2 heavenly dragon and the fact is that 14 solar system is only equivalent to like 1/10,000,000 of a average galaxy(3-C).

Woo Is you know how they killed even thoughts it's not mentioned sides from that their body being destroyed in great war

Who destroyed, why destroyed, what weapon used nothing is mention

Even If its cause by dragon slayers poison that absorbs infinite-1 of Ophis power, she will still have infinite power nevertheless. Not to Mention it impossible to for a finite character to get reduced into a finite being by a power created by a finite being in a first place

No argument, since nothing mentioned about this how this work only thing we can do it Self-Conceptualized

If the Heavenly Dragons were truly capable of destroying a world/universe (Low 2-C), then how do you explain them being taken down by 4-C beings? Either their supposed world/universe destroying power is an outlier, exaggerated, or it doesn’t apply in actual combat. If they were Low 2-C in attack potency and durability, then nothing below that tier should have been able to harm them, let alone defeat them. If they were beaten by 4-C or 4-A beings, then their so-called ‘universe/world destruction’ statement is hyperbolic, misinterpreted, or only refers to something less than an actual space-time continuum destruction. Do you have concrete evidence showing that they can erase or collapse an entire space-time continuum at once? Because if not, their Low 2-C scaling is extremely vague at best. From what I read In the novel there are no weapons or powers mentions that are used by the 3 factions or any other pantheon which I doubt they participate in the first place are capable of low 2-C Destructive prowess and as for on how their bodies was destroyed, is that there are no other than the 3 factions who participated the battle and destroyed them and don’t bring up the god of the Bible whose participation is to seal them in the sacred gear after they were killed

No argument, since nothing mentioned about this how this work only thing we can do it Self-Conceptualized

The issue is that if Ophis was truly infinite, then no finite force; whether a poison, weapon, or ability, should ever be able to reduce her to a finite state. The fact that she was weakened suggests one of two things: either her ‘infinity’ is not a literal infinite power, but rather a hyperbolic statement or a different kind of concept, or the poison itself has some form of conceptual or reality-altering property beyond simple numerical absorption. But if no details are given about how it works, then assuming it somehow ‘reduces infinity to finite’ without an explicit explanation is just self-contradictory, unless you have direct proof that Ophis’ infinity is infinite as claimed to be and not just a very large but finite amount of power?

Dragon are weak to dragons slayer like how issei destroy Vali bxb like paper and as dragons slayer poses by the angels during great wars maybe they used against two heavenly

also two heavenly Dragons are fighting each other continuously before they attack three faction so possibly they become weaker since they are not infinite there are many method that can kill Dragons in dxd

No argument since it's never stated how ophis infinite work and how poison of God works

Ophis has infinite power or power of infinity are continuously stated across many volume

 

[Burning_Full_Fingers]

But dxd has concept of different timelines crossover will be one of them ( in crossover two dxd world appear) and they explained like taking a different path destiny create new timeline

Yes, different timelines exist but it doesn’t scale to anything aside from Melvazoa’s immortality.

ExE is Higher dimension ( twit by author)

he said “higher dimensional breast gods”, which may or may not have been a joke tweet.

Season 5 when

Keep dreaming, much like the novel fans. Have no idea what’s going on with the series at this point.

 

[Dragongod224]

Yes true, but l am not the one who saying that any one scale to this level currently

he said “higher dimensional breast gods”, which may or may not have been a joke tweet.

True

 

[Burning_Full_Fingers]

Yes true, but l am not the one who saying that any one scale to this level currently

True

I don’t get why Masque thinks they scale to the timelines (?) then. We’ve argued about this before.

They should focus on the limits of what we’ve seen for the main timeline Draconic Deus; that is, the dimensional gap. There’s no proof one dimensional gap exists for every timeline.

Fantasia being translated is good for the storyline and maybe crossover profiles as well. But not canon DxD.

As for ExE, we’d have to wait for Ishibumi to continue the story which doesn’t seem like it’d happen anytime soon, unfortunately.

 

[Hasty12345]

It’s probably bad faith to be using language that portrays another user in a bad light when they’re not here to refute your points or defend themselves.

Ask AI how powerful issei is


Whether Issei Hyoudou from High School DxD can destroy a multiverse depends on how we define "multiverse" and where we place him in his power progression, particularly based on the light novels (since the anime hasn’t caught up to his strongest feats yet). Let’s analyze this step-by-step based on his abilities and the DxD universe’s scale as of the latest developments (up to my knowledge in February 2025, reflecting the light novels through Volume 25+).
What’s a Multiverse in High School DxD Context?
In High School DxD, the "multiverse" isn’t explicitly defined as a collection of infinite universes like in Marvel or DC. Instead, it encompasses:
The human world and its parallel dimensions (e.g., Underworld, Heaven, Norse realms like Asgard).
Separate mythological systems (Greek, Norse, Hindu, etc.), each with their own gods and realms.
The Dimensional Gap, a chaotic void between worlds, home to entities like Great Red and Ophis.
Potential alternate timelines or pocket dimensions (hinted at but not fully explored).
So, "destroying a multiverse" in this context could mean obliterating all these interconnected realms or wiping out existence on a scale beyond a single universe. Let’s see if Issei’s power reaches that level.
Issei’s Strongest Forms and Feats
Diabolos Dragon (DxD) Form (Volume 21)
Power Source: Combines Boosted Gear’s infinite scaling, Ophis’s infinite dragon power, and his Pawn Evil Pieces.
Feats: Defeats Rizevim Livan Lucifer (a Super Devil), fights Apophis (a Dragon God), and generates energy that threatens entire regions of the Dimensional Gap.
Scale: Capable of destroying planets or large swaths of a dimension with sustained effort. His "Infinity Blaster" attack is described as having apocalyptic potential, but it’s still localized to a single realm or battlefield.
Multiverse Potential?: No explicit multiverse-level destruction here. He’s more at a planetary-to-dimensional scale, far below wiping out all realms.
AxA (Apocha x Apollyon) (Post-Volume 25)
Power Source: Merges Boosted Gear with Ryuuuteimaru (his familiar, now a massive dragon battleship) and draws on Great Red’s power (the Dragon of Dreams, who sustains the Dimensional Gap).
Feats: Described as having "world-destroying" capabilities. In Volume 25, it’s suggested AxA could potentially threaten the stability of the DxD world’s structure if fully unleashed. It’s still experimental, and Issei hasn’t mastered it.
Scale: The term "world" here likely refers to the entire DxD setting (human world, Underworld, Dimensional Gap, etc.), not infinite universes. Great Red’s power is tied to stabilizing the Dimensional Gap, so AxA might disrupt that, causing a cascading collapse of connected realms.
Multiverse Potential?: This is the closest Issei gets. If "multiverse" means all DxD realms, AxA might theoretically achieve it with refinement—but it’s unproven and speculative.
Comparison to Multiverse-Level Threats
Trihexa (666): The Beast of the Apocalypse is the benchmark for multiverse-level destruction in DxD. It’s stated that Trihexa could destroy all mythological realms and the human world if unchecked, requiring the combined might of gods, dragons, and devils (including Sirzechs and Ajuka in their prime) to seal it. Issei in DxD form helped fight its core, but he wasn’t the decisive factor—teamwork was.
Issei vs. Trihexa: Even in AxA, Issei hasn’t shown the raw destructive output to solo Trihexa, which suggests he’s below true multiverse-busting power.
Great Red and Ophis: These Dragon Gods are the pinnacle of power in DxD. Great Red sustains the Dimensional Gap, and full-power Ophis (before her nerf) was considered infinite. Destroying a multiverse would require surpassing them, which Issei hasn’t done yet—though AxA borrows their essence, hinting at potential parity.
Can He Destroy a Multiverse?
Current Feats (DxD Form): No. He’s at a planetary-to-dimensional level, capable of wiping out large regions or realms (e.g., the Underworld or Asgard), but not the entirety of the DxD multiverse.
Potential (AxA Form): Maybe, but it’s unconfirmed. AxA’s "world-destroying" label suggests it could destabilize the DxD world’s framework (all realms + Dimensional Gap), which might qualify as multiversal in a limited sense. However, this hinges on:
Mastering AxA fully (he hasn’t yet).
The DxD "multiverse" being smaller than infinite universes (it’s more like a single cosmology with multiple dimensions).
Even then, there’s no evidence he could destroy infinite realities like a true multiverse destroyer (e.g., Zeno from Dragon Ball Super).
Limitations:
Stamina: His strongest forms drain him quickly.
Control: AxA is unstable and risks collateral damage to allies.
Narrative Role: Issei’s story focuses on growth and protecting, not annihilation, so multiverse destruction isn’t his trajectory.

Conclusion
As of February 22, 2025 (reflecting light novel developments), Issei cannot definitively destroy a multiverse. In his DxD form, he’s a dimensional powerhouse but not multiversal. In AxA, he has theoretical potential to collapse the DxD world’s interconnected realms—maybe stretching to a "small multiverse" if you interpret it generously—but he’s not at the level of obliterating infinite universes or rivaling cosmic entities like Great Red or Trihexa solo. His power is insane, but multiverse-busting remains a step beyond his current reach.
Want me to speculate further on where his growth might take him, or compare him to another character?

Interconnected realms, dimensions isn't multiverse

Interconnected realms, dimensions isn't multiverse

Can you explain in detail

 

[BlackeJan]

Yeah I can’t wait to get the scaling fixed cause we got people scaling just cause they are in a certain rank when Issei is the main reason why that shouldn’t really matter

 

[Burning_Full_Fingers]

Yeah I can’t wait to get the scaling fixed cause we got people scaling just cause they are in a certain rank when Issei is the main reason why that shouldn’t really matter

It is accurate and the author still uses it as a benchmark. Issei and some others are the rare 1%.
