I'll make this quick. There's a user who goes out of their way to respond to every post about complex multiversal Super Dragon Ball Heroes to redirect people to their SDBH cosmology debunk post, and I wanted to respond to it. To be clear, I don't care what you buy for Archie or SDBH or DC, Marvel, SCP or anything. You can consider SDBH wall level, it doesn't matter. I just felt compelled to make this post because the user in question is acting like a bit of an obnoxious jerk about it while their debunk post has a few glaring flaws.

The Afterlife is a higher dimensional realm according to the guidebook: Not really? All I could really get by translating this text is that it is higher than heaven and beyond human understanding. Regardless, the Afterlife at no point shows any higher dimensional properties (which the Chaos Force from Archie Sonic does, being incomprehensible and being seen differently depending on the observer), the Afterlife is just treated as being another realm, so even if the scan did claim it to be higher dimensional, it would be in conflict what is shown in the actual story, and the actual story obviously takes precedence. Before anyone brings it up, the exact same thing applies to the Kaioshin Realm. Nothing here really qualifies as higher dimensional.

I find something problematic almost imediately. I don't know whether this user did it on purpose, but they used fake text to debunk the afterlife guidebook scan. For whatever reason, the text they translated left out the characters pertaining to dimensions. This is the actual guidebook raw text on the afterlife: 天よりも高く、人間界からは窺い知ることができない次元を超越した天の国神々はこの地から世界のすべてを見おろしている.
Now here's the actual, official, English translation for it: "Higher than the sky, a dimensionally transcendental heavenly country that cannot be perceived from the human realm. From this land, the gods look down upon the entire world." Toriyama stated in an interview that it's normally inaccesible to living beings, and this is backed up by guidebooks. It is impossible to reach the afterlife from the living world through conventional means, and it's impossible to reach the Kaioshin realm from the afterlife through conventional means. The living world is also described relative to the afterlife as the temporal world (of or relating to the dimension of time, as distinguished from space). The narrator states that other world and the living universe are seperated by time and space. The idea of dimensions above time isn't foreign to Dragon Ball, seeing as Jiren was stated to have power transcending time (before you suggest that maybe it meant he could just resist time hax, I made another post responding to that). So yeah, I don't exactly see how the afterlife is 'treated like any other realm.' In addition, the Kaioshin realm actually encompasses heaven (the afterlife), so I don't see how "the same thing applies to the Kaioshin realm."
You could say "but dimension could be a synonym for a realm or universe" in response to the first afterlife scan, but the word "dimension" is far less flexible in Chinese/Japanese than it is in English, and Chinese/Japanese use the characters 世界 (world) or 領域 (realm) when naming alternate universes. The word used to describe the afterlife's transcendental properties was 次元, which refers to dimensions of math/physics in spatial contexts (次元解析=Dimensional analysis, 次元正則化=Dimensional Regularization, 三次元 =3 Dimensional, 高次元 =Higher Dimension, etc.). The only time 次元 is used to name an alternative universe is in abstract reference to a higher plane of existence, like how the higher planes of existence are described in Journey To The West. Oddly enough, not only is Dragon Ball lore directy inspired by Asian mythos like JTTW specifically, but the afterlife is described with fairly abstract language as a higher plane of existence itself.
That's it for canon stuff. Now, the overwhelming majority of people already accept that the SDBH multiverse has anywhere from countably infinite timelines to several sets of infinite timelines, so I have nothing to prove there. But before moving on, I wanted to link a blog post arguing that SDBH has uncountably infinite sets of infinite timelines based on many-worlds interpretation (a concept not only described in canon dragon ball, but named directly in an article on Toriyama/Toei's official dragon ball site where an astrophysics professor and long-time dragon ball fan was brought in to explain the mechanics of time travel in dragon ball). There's a very widespread misconception that all the dragon ball forums and youtubers perpetuate where canon dragon ball has only several sets of timelines based on the few time rings, which represent timelines. In reality, green time rings represent timelines created through time tampering, silver time rings represent naturally branched timelines, and the time rings exist in groups of several inside boxes from an endless room of time ring boxes that each supreme kai has.

The Crack of Time is separate from the dimension of time: Yes, but this doesn't automatically make it higher dimensional, it just means it qualifies as a timeless realm. This is certainly impressive, since it gives those who can move through it Immeasurable speed (Immeasurable speed is actually super consistent in Dragon Ball Heroes), but it does not make the cosmology higher dimensional. The Crack of Time is never directly mentioned to be higher dimensional or ever shown to have higher dimensional properties (which again, the Chaos Force does.)

Before getting into this, one thing I find interesting is that this user asserts that being timeless/unbound by time doesn't indicate transcending time as a dimension, when they said in another post that the phantom zone is outerversal because it was described as being "without dimensions" (as opposed to transcending dimensionality, which is the actual definition of outerversal). Anyhow, back to the crack of time's properties...
It's stated to be seperate from the dimension of time. The crack of time is further described as a space beyond time. Even following the complete destruction of SDBH's infinite multiverse, no damage to the crack of time was mentioned or demonstrated visually. Demigra stated that Chronoa and Mechikabura were sealed outside of time itself, and we see the seal in question (labyrinth of time) within the crack of time.
Most conventional time traveling mechanisms can't be used to traverse the crack of time. The crack of time contains the multiverse of infinite timelines in the form of small crystals. In all the SDBH media where the crack of time appears, infinite timelines appear finite and 3d. From the perspective of the crack of time, Fu's distorted artificial universe is smaller than an arm. This means creatures overall become larger than the aforementioned space-time continuums when entering the crack of time.
While within a timeline, even the highest beings in the cosmic hierarchy like the angels and gods couldn't affect the universe tree while it was located in the crack of time. For that reason, Super Shenron could only erase its roots but not the tree itself.
In ultra god mission, the narrator states that the gathering warriors have transcended time and space to reach the crack of time (超えた primarily denotes qualitative superiority). This is consistent with the official SDBH twitter page describing the tournament as super-dimensional. V-Jump magazine also describes this battle as super-dimensional. The battle is also described as hyper-dimensional. We know this place is the crack of time based on the description and the background of the place, which is the starry sky of the crack of time.
Now, let's talk bout the characters 超時空. 超 is a prefix meaning supehypeultra. As a verb, it means "to transcend," and it primarily denotes qualitative superiority. 時空 refers to "space-time" or "spatiotemporal." As an adjective, 超時空 translates as "super-dimensional" or "hyper-dimensional," and as a noun, it describes a "hyperspace." Now, what is a hyperspace? The term hyperspace originated in 19th century math texts in the context of higher-dimensional space, and is still used under that context by modern theoretical physicists. The folding model is a common explanation of the higher dimensional properties of a hyperspace, and it describes how the dimensional space below the hyperspace is distorted to converge distant points. Since the crack of time converges the infinite timelines as I explained above, it fits the folding model's definition of higher dimensional hyperspace.
Also, you can't argue that words like "beyond time and space" are too ambiguous when the crack of time's descriptors clearly denote qualititve superiorty, as I explained above.
Where are we so far?
Under conservative interpretations...

1. SDBH has anywhere from countably infinite timelines to several sets of infinite timelines.
2. The Crack Of Time transcends that infinite multiverse.

Here we have a low complex 5-D multiverse thus far.
Under liberal interpretations.

1. Every macrocosm in Dragon Ball is 5-D since the afterlife dimensionally transcends the rest of the lower realms, some of which exhibit characterists of 4-D space-times (I can expand on that, if you want). There are other arguments out there for 5-D macrocosms, but I'm using this one since it's the one I explained before.
2. Through many-worlds interpretation, SDBH has countably infinite sets of infinite timelines (as explained in the blog I linked before) with multiverses of 5-D macrocosms that amount to a 6-D multiverse.
3. The Crack Of Time transcends that infinite multiverse.

Here we have a complex 7-D multiverse thus far.

Demigra is stated to transcend time and space: No, he is not. It is said that he "is at the end of the adventure beyond time and space." The "beyond time and space" is not referring to him, but to the adventure itself, which means this is clearly just more flowery language as a way to say Demigra is the final boss of a time travel game.

An adventure which took place in the crack of time, which I already addressed. Let me further contextualize Demigra's power. It gave him control over all of time and space, which allowed him to warp the time vault/shrine, which is a realm connected to the 5-D crack of time. His fight against the future warrior in the crack of time also caused the realm to crumble.

Xenoverse is said to include extra-dimensional worlds: There is really no evidence that this is referring to a higher spatial dimension. It could just be referring to them being disconnected from time (which would be consistent with them being located in the Crack of Time), or it could also be referring to them simply being branching dimensions created due to time travel. This statement is too vague to assume a higher dimensional cosmology from it alone.

I already explained hyperspaces and the crack of time. Something I should add though, is that in the ocassions where Japanese people will use flowery language to describe something as otherworldy, they primarily use the phrase 別世界, which is not the phrase used in most of these "super-dimensional" descriptions.

Goku was stated in a card to have power that transcends dimensions: There is really no evidence that this is referring to spacial dimensions. It could very well just be referring to universes, or just a flowery way of saying Goku's power is on a whole other league when compared to the other fighters. Saying Goku is higher dimensional simply because of a one-off statement such as this is really pushing it.

I can't say much about this part, since I don't know what scan they're reffering to, but I get the feeling that the word used for dimension was 次元, which already refutes the "universes" part.
Edit: So I found the scan, and this was the text it contained: 次元を超越した最強パワー, which translates to "the strongest force that has transcended dimensions." 次元 refers to the physics concept of dimensions (or in some contexts, higher planes of reality), and 超越 refers exclusively to qualitative transcendence. I guess I can't form a conclusion on this? It could refer to the dimensions in the game, dimensions as a whole, it could mean "hyperdimensional (超次元)," or it could just exemplify his extreme power (which isn't remotely mutually exclusive with higher dimensional power). Nothing I can assert here.

Beat's World views Dragon Ball as fiction: Yes, but this doesn't automatically make it higher dimensional. It is a misconception that simply viewing something as fiction automatically makes it higher dimensional, as there are multiple examples of "real worlds" that aren't really treated any different from any other universes, such as in Marvel or in Dark Tower. Beat's world has no evidence of being higher dimensional and does not show higher dimensional properties, it is just a regular universe in which Dragon Ball happens to be a work of fiction. Even base form Sonic has come to the real world, twice. "Real world" really doesn't mean anything unless there is context to assume it is higher dimensional, which Beat's World does not have.

I see 2 red flags right off the bat.
First off, this user said in a recent debate that the limbo realm in DC is higher dimensional since it views the creation beneath it as fiction, so unless I'm strawmanning them, their reluctance to approve of that criterion seems rather inconsistent.
Secondly, while people tend to abuse reality-fiction transcendence to wank Popeye for punching his animator, wank Saitama for drawing his own manga, or wank Spongebob for walking outside his comic, reality-fiction transendence is a core aspect of the dimensional tiering system founded by Vs wiki. It's not just some toonforce/4th wall thing that arrived out of nowhere, it's always been a possible qualifier for a higher dimensional space.
Anyway, the idea that Beat's world is just another universe where dragon ball just happens to be a popular work of fiction comes from Beat being described a distant descendant of GT Goku, and Xeno Goku suggesting that Beat's world is essentially a future version of his own. There are other references to Beat's world being akin to the saved future of the Dragon Ball GT's world. As the Vs Wiki page on reality-fiction transcendence explains, this is only a disqualifier if the "real world" in question also fails to demonstrate any kind of transcendence, the fictional characters are treated like any other character, and the fictional characters can enter it without becoming "superior" in notable ways.
Demigra had to warp existence and transcend space (reffering to SDBH as a whole) to reach Beat's world. Frieza had to be imbued with dark energy to reach Beat's world, which is consistent with SDBH villains requiring dark energy to transcend time and space (only demon gods, supreme Kais of time, and others comparable in power can normally access the crack of time). The denizens of Beat's world view active SDBH world as an arcarde game and manga. Upon entering SDBH, the Great Saiyaman 3 from Beat's world said the mechanics and characters shouldn't feel so realistic. SDBH characters and players within the game world are described as avatars.
Under normal circumstances, characters can't traverse between Beat's world and SDBH without dimensional transfer technology. Reaching Beat's world is described as overcoming dimensional barriers. In victory mission, Beat was more shocked with the Shadow Dragons reaching his world than he was with them threatening the DBH multiverse, implying that affecting his world is especially impressive. You could argue that the dimensional transfer technology is just standard teleportation tech, but if that were so, there's no reason SDBH character can't reach it with their own space-time manipulation as opposed to gaining the power to transcend space. Let's look at the Vs Wiki page for reality-fiction transcendence.
Qualifier: The real world has to view the other world as a sort of fiction, where anything that occurs shouldn't affect them. From Beat's world, the entirety of SDBH is contained within the arcade game and other visual media, SDBH characters and mechanics are viewed as unrealistic, the arcade characters they manipulate are described as avatars, and the act of affecting Beat's world is considered a surprising phenomenon.
Disqualifier 1: The realities are portrayed like parallel universes or otherwise as having just a finite difference in scale or having a similar nature. Beat's world demonstrably has features that disniguish it from SDBH timelines, as explained above.
Disqualifier 2: The fictional characters being able to attack the real ones without being shown to somehow have transcended their fictional world or having special abilities that allow it. Already went over this.
Disqualifier 3: The characters from both realities are generally being portrayed as comparable in power. This point has some merit, but you have to contextualize it. This means within their respective realms, the real world is portrayed as having qualitative superiority over the fictional one (going back to the whole "they can't be portrayed as parallel worlds" thing). Think about Apokolips and the multiverse. When New Gods downsize themselves through boomtubes to fight the justice league as avatars, they're roughly comparable in power. When the justice league upscales themselves to the Apokolips to fight New Gods, they can go toe to toe. But in normal circumstances, when mortals are confined to their world and New Gods are confined to theirs, the New Gods demonstrate a far greater capacity to warp the lower multiverse. When SDBH characters are confined to their own world (no transcending space jazz), Beat's world denizens demonstrate a greater capacity to warp it via playing the game.

The Japan that oversees the Dragon Ball Heroes card game sees it as fiction: Same thing I said about Beat's world applies here. "Real world" doesn't mean anything.

I already went over fictional transcendence. This Japan is admittedly lacking on scans and information, but from what we have, it not only monitors Beat's world, but contains it in fictional media the same way SDBH is contained in the visual media of Beat's world.
That's basically it for the user's debunk post. There are other structures in the SDBH cosmology, but that's outside of this post's objective.
Closing rant: I haven't been on this sub as long as certain others, but I have to take a break for some months. Debating has just turned so toxic. Everyone is outerversal now, everyone has a vendetta for no good reason... take what you will from my post, consider SDBH pebble level if you want. I don't care about proving a point, as I blocked the user in question. One thing I have to say though is that it's weird how high a standard Dragon Ball is held to in certain debates. If this were any other verse, I wouldn't have to type paragraps at a time for individual structures in the cosmology. Arceus was stated to transcend Pokemon's infinite multiverse, and that's enough for most people to accept him as low complex. So many fictional verses have "real worlds" that are mentioned in passing, and that's enough for them to be +1 dimensional (or often outerversal). I might be wrong, but don't most of XDive's higher dimensional arguments hinge on the game's depiction of our "real world?" On another note, why's there so much hostility between Dragon Ball fans and Sonic fans here lately? To be honest, it's mostly driven by Dragon Ball fans. It's all so pointless. I spent over 12 hours making this post. I skipped dinner and breakfast, and only took some hours to nap... and all for some power scaling debate? Lol, I've become a mess. I should be worrying about my undiagnosed OCD and the fact that I might go homeless in 2 months. Imma turn off the notifications for this post. u/itownshend17 and u/LasyTaco, I'll miss you guys the most (though we probably don't know each other).
Hope I didn't leave any spelling errors or unclarified/unrefined points.
Just be nice for crying out loud.
